Chapter Two: Protecting My Students

I remember… Being Hokage. I had finally reached my dream of being Hokage. Damn… it was amazing. With my wife by my side, and my best friend supporting me, there was no way I could fail! Except… being a father… I vowed to protect them. I promised her that I'd be a wonderful father. I assured her that my job would come second. But… I didn't do that very well… And when my son was kidnapped… Everything went to hell. He was gone… And only my little girl remained. We thought… we thought we'd never find him. But he came back. And when I tried to welcome him with open arms, he shoved a blade through my heart.

I remember… being a mother. My little girl was so precious to me. My husband though… he was changing. He was going out more, and it worried me. Why wasn't he here to spend time with his little girl? Or me, for that matter? Even Weiss-cream was becoming concerned, and she was married to the king of aloofness! Then… It all happened so fast… My husband took me out on a lovely dinner. We had a wonderful time! Or… so I thought… After the date… we went on a nice, long stroll… I knew my little girl would be safe. She was with her Aunt Blake after all… But he… he was ready… He had a mistress… I was never enough… So… he threw me into the woods… Where he'd butchered dozens of people… Their negative feelings were still lingering… Without my weapons, I never stood a chance…

I remember… watching my sensei and best friend fighting a king. I was paralyzed, helpless to watch on as, even though their teamwork was flawless, the king's mighty shield and defenses whittled them away to nothingness. I hated myself for being so weak. Even in this dire moment, I was helpless. So I screamed. I screamed and roared until finally, I gained the strength to move. I ran as the king tried to strike down my friend, and… pain… Incredible pain as his blade pierced my chest. Then… darkness. Then I awoke.

[With Hyoudou Issei]

Issei stood nervously in front of his English teacher's door. It was one of those small apartments on the outskirts of town. It wasn't really bad, but there were better places to live as well. He'd been coming for the last week for tutoring sessions, but for the most part, he and Kai just goofed around playing video games and talking. He could hear loud jazz playing from behind the door, his teacher's favorite genre of music. But he wasn't here for just talking, or even tutoring. He had a much more important thing on his mind! A girl from school, Amano Yuuma, had asked him on a date! While he was obviously very excited, he had asked her for a day to prepare himself. The girl had eagerly agreed, and Issei had rushed to find his teacher for advice.

So here he was, knocking on the door of his favorite sensei. The guy was pretty cool, if not a little weird. He seemed to space out at random times of the day, and was eccentric almost all the time! It seemed like the guy could never be sad or angry. Still, he was definitely a good guy, Issei was sure of it. As he knocked, the music stopped and the door opened, revealing Kai in a disheveled state of dress. It wasn't really unusual to find him at home like this, half out of his uniform and playing some sort of video game. Or cooking. For some reason, Kai was a very good cook. When he had the money for ingredients, anyway. His ramen was to die for, anyway.

"Yo, Issei-kun!" Kai exclaimed in Japanese. While his normal rule was to always speak English, Kai had let Issei off easy after intense tutoring sessions, and the brown-haired boy had proven himself fluent in the foreign language. "What's up, little man?" Issei grinned. Kai was never judgmental of him, and actually encouraged him to be a pervert. Or a "Super Pervert", as Kai had dubbed him. The only thing that Kai had insisted on was that Issei pull himself back from peeping in public. Issei had quickly agreed out of respect for the older man.

"Hey, I need some advice," Issei spoke to his teacher like a friend. He took off his shoes as he entered, setting them to the side before walking in with Kai. "I've got great news, sensei! I have a date tomorrow!" Kai, who had been sat down at his desk writing on his computer, immediately stood.

"A date!?" he shouted with excitement. "Aw man, that's awesome! What's her name? what year is she?" Issei cringed. Oh no, he was going to be like an overbearing parent, wasn't he?

"K-Kai-sensei, calm down!" Issei protested. "Her name is Amano Yuuma, sensei." Issei spoke dreamily. "And she's… she's perfect! She's sweet, and shy, and kind, and she has these amazing oppai!"

"Now hold on there, boner boy," Kai raised his hand, shaking his head. "First thing you've gotta do is take that dick outta your head and replace it with your brain."

"S-Sensei?" Issei stammered. "Don't you see!? Her oppai! They're incredible, and she wants me of all people!"

"I know, my brother," Kai rested his hands on Issei's shoulders, but a serious expression was on his face. "However, to properly court a woman, you must be a gentleman. I will give you the sacred advice of God- ow, on how to date a woman properly!"

"Yes, sensei! Teach me your ways!" Issei was on his knees, a notebook and pen pulled from his pockets. Kai grinned and stood the boy up. "What should I do first, ero-sensei?"

"First, never call me that again," Kai grumbled. "Alright, first off, dress well. You want to show her that she's worth your time, so don't dress in…" Kai looked over Issei's messy school uniform. "That. That's very bad," he told the boy, motioning over the uniform. "Secondly, you pick the places to go on the date. No requesting, no asking, you tell her exactly what you two will be doing. Not only will it show that you're a man who knows what he's doing, but it also shows that you're willing to put effort into the relationship. I recommend simple places for a first date, like a restaurant, movie, or if she enjoys such things, an arcade."

"Hai, Kai-sensei!" Issei saluted. "Is there anything else?"

"The last few things," Kai told him. "Firstly, by the end of your date, buy her something small to remember you by. It can be a stuffed animal, a small accessory, or something similar. Lastly…" Kai paused, causing Issei to lean forward. "Be yourself, bud. Don't try and act cool or tough, because you aren't." Issei slouched. "But that isn't a bad thing. You're a pretty smart kid, Issei-kun. Show her that, but don't be arrogant about it. No girl wants to stay with a man who's going to one-up her all the time. Also… hold back on the pervy nature."

"B-But Kai-sensei!" Issei started to protest. "Her oppai!"

"They can wait," Kai stated matter of factly. "I can be assured you're a virgin, right?" Issei blushed at the question. "Save yourself the pain and wait a while. Wait for that special girl you know you'll always be with. For all we know, this Yuuma-san might be a complete bitch on the inside. It's worth the wait, alright bud? Don't make the same mistakes I have." Issei frowned, noting the bitter look on his teacher's face. "Promise me."

"I promise, sensei," Issei replied, backing towards the door. "Thank you very much, sensei! I'll see you in school tomorrow!"

"Seeya, bud!" Kai chuckled, grinning at the boy as he left. As Issei closed the door, Kai went back to his computer, switching from his story to the news. Spottings of a mysterious woman appearing all over the world, Arabic in looks. Miracles seemed to happen around her, and she preached love and equality wherever she went. Kai couldn't help the dreamy smile that crossed his face. "My darling…" he whispered, sighing. "Why haven't you come for me, yet…?" He frowned, sitting back in his chair. She'd been all over the place, except in Japan. For some reason, there was a demonic aura over Japan, more specifically Kuoh, that seemed to keep anything purely holy out. While humans could probably cross the border, Angels and deities were likely kept out. He wouldn't be surprised if his beloved couldn't even sense him. It wasn't a matter of her not loving him, perhaps, but a simple case of her literally being unable to find him. Unless he left Japan, she might never find him. It broke his heart knowing this.

He was interrupted from his musings as he heard a knock on his door. The reincarnated Devil groaned, switching his screen back to his writings as he approached the door. "What else, Issei-kun?" he asked as he opened the door, instead coming face to face with not a brown haired boy, but a lovely red-haired Devil.

"Hello, Kai-san," spoke the red-headed Devil. Behind her stood a young woman with violet hair tied back in a neat ponytail, and violet eyes that held amusement at the teacher. The two great onee-sama of Kuoh Academy.

"Gremory-kun," Kai nodded towards the redhead. "Himejima-kun," he also acknowledged the woman standing behind her. "It's been quite some time since you've paid me a visit. I was beginning to feel unloved." Kai smirked. "After all, is it not the [Knight's] job to stay by the side of his [King]?"

"You know that such things would hardly be appropriate in school," Rias replied, taking a step forward. "May we?"

"Anything for my [King]," Kai chuckled, stepping back into his single room apartment. He walked to his small makeshift kitchen, setting out a small kettle and filled it with water. "Tea?"

"No, thank you," Rias replied.

"I would love a cup, Kai-san," Akeno replied after her [King]. Rias took her shoes off and sat in the chair Kai had previously been in, as Akeno stood by her side. Kai took his time in preparing the tea, an ocean's worth of thoughts running through his head. He had thought there would be more time until a decision was needed to be made. Before Riser made his play. Were things coming early? He had heard from Sirzechs about how unpleasant Riser was, and was not looking forward to meeting the boy.

"I noticed that Issei-kun has been visiting lately," Rias spoke up as Kai handed a fresh cup of tea to Akeno. Kai seemed to freeze, however, at the words.

"Is that wrong," he asked, almost fearful. Rias winced at his words. It was always like this. She couldn't have a simple conversation with him without Kai tip-toeing around his words and actions. It was like he was afraid she would punish him like some other Devil.

"Not at all," Rias reassured Kai. "However, he apparently has a date with a Fallen Angel, tomorrow." Kai frowned, shivering just a bit with anticipation.

"Amano Yuuma…" Kai mumbled under his breath. "Wait, you know about this!? You… You want his Sacred Gear…" Kai's face morphed into one of disgust. He crossed his arms, standing directly in front of the two young women. "That's twisted. You know that this Fallen Angel will kill him, and yet you'd happily sit back and let them, just to have an assured new piece to your peerage!?"

"Kai-san," Rias stood and raised her hands defensively, trying to placate her rather new [Knight]. "It's not quite like that. If he dies, then of course I'll reincarnate him. However, that's not why I've come. I want you to keep an eye on Issei-kun during his date, and ensure his safety. After the Fallen Angel attacks him, I'll personally confront him and ask him if he'd like to join my peerage."

"You're still playing the poor kid right into your hands, Rias-san," Kai growled, his right eye twitching. "You have no right to be playing with the life of-"

"Silence!" Rias shouted, her patience run out. "You don't seem to understand your position here, Kai-san. I am your [King]. While I respect your opinions and your protests, what I tell you is final! Do you understand me, [Knight]?" Kai was growling under his breath. He hated being told what to do, but he could feel the piece inside of him twisting his mind. Suggesting that obeying her was definitely the right thing to do. Even if he knew that Issei would die. He didn't want to subject the poor kid to a life of eternal servitude, with absolutely no means of escaping. Kai was fine with it, but it was only because it gave him another chance at life. One where he could make a difference in the world. But Issei? Despite all the credit Kai gave him… the kid was only a pervert. There wasn't much he really would desire except naked flesh. This kind of life wasn't ideal for him.

"For the record," Kai growled under his breath. "I told you this was a bad idea. He might have an incredible Sacred Gear, but you don't have long to train him in it. It won't be enough to defeat Riser."

"With all due respect, Kai-san," Akeno spoke up. "But do you think that you are enough?" Silence was her only answer. "Isn't it hypocritical to suggest as much? After all, you're in the same position as Issei-kun."

"I've had experience on the fields of war!" Kai growled, his eyes narrowing dangerously. "Nothing Issei has ever done would prepare him for a life and death battle!"

"Your 'fields of war' are all video games," Rias retorted. "In that regard, you're no better than Issei-kun. Now, we can stay here and argue this moot point all night, but what's done is done, Kai-san." Rias shot the older man a hard look. "If I knew you would be this insubordinate, I would have asked my brother to keep you for himself. You've yet to even join my peerage in hunting Stray Devils in the area. I have no idea if you're truly ready for combat, either." Kai was silent, but Akeno could see that his fists were clenched. She readied herself for a fight. If he were to make a move to hurt her [King], she would eliminate him quickly. Perhaps it wasn't a great idea to include such a volatile piece into Rias' peerage. "Come, Akeno. We should prepare for tomorrow." The violet haired beauty nodded, keeping a close eye on Kai as they left, ensuring that he made no sudden, or violent, movements.

[With Hyoudou Issei] [Two Days Later]

The brown haired boy walked through the thick of night, going home from school. It was a really weird day. First, nobody seemed to remember Amano Yuuma. Even Kai had denied even hearing of his psychotic ex-girlfriend! It was infuriating to say the least. Second off, he was starting to feel weird, maybe even a little sick. The sunlight, he found out, seemed to drain him of his energy and vigor. It was a weird thing, but definitely not the worst part of his issues. No, the worst part was that his ex had killed him! Stabbed him right through the chest with some sort of beam of light! How he was still alive? Issei had no clue. But it was something that he wanted to figure out.

"Well, what do we have here?" spoke a particularly creepy voice from behind Issei. The boy looked around frantically, searching for the owner of said voice. "How cute, he doesn't even know that his enemy is above him." Issei looked up, spotting a man in some sort of tacky trench coat and a fedora. He looked to be in his late thirties, and had a menacing gleam in his eyes. He also had a pair of black wings like a crow. Like Yuuma!

"Hey, who are you?" Issei shouted, backing away slowly. He wasn't sure he wanted to be impaled again. Especially not by another guy!

"Where is your master, Devil trash?" asked the weird, creepy guy. "Or are you a stray? It matters not, I'll have your head regardless!" A bolt of blue light appeared in the man's hand and he raised it as if he were about to throw a javelin. Issei turned and started to run. "You can't escape me you filthy Devil!" the guy shouted, hurling the spear of light at Issei. It roared with power as it moved at almost blinding speeds at the boy.

"Dynamic Entry!" someone shouted. Out of nowhere, a figure slammed into Issei, knocking him out of the way of the light spear. The figure twisted, also avoiding being impaled. The man grinned, chuckling to himself as he stood up straight, staring down the Fallen Angel in front of him. "Oh man, what a rush!" Kai stretched, grunting as he loosened his muscles. "I haven't had to move that fast in a long time!"

"K-Kai-sensei…?" Issei groaned, sitting up in the bushes he'd been kicked into. Kai smirked and wagged his finger at the boy.

"Shhhh, bud. Mommy and daddy will be done talking, soon," chuckled the older man. He turned to face the flying Fallen Angel. "Now then, as much as I want for our two races to get along, harming my students is strictly against the rules."

"Ah, another weak Devil makes no difference," spoke the shady man. "I'll simply eliminate you, the greater threat, first." Two more light spears appeared in the man's hands, thrown within seconds at Kai. The young man grinned, ducking, weaving, and rolling away from anything that came his way. His eyes sharpened, taking in the details of the incoming attacks. Fast, but thin. The man was aiming at where he was, and not where he'd be. Amateur.

"Head's up!" Kai shouted, wings appearing in an instant as he launched himself at the man. "Time to clip some wings!" Kai grinned, grabbing the man by the head. He had moved so quickly, the man had no idea what had just happened! "First Floor, information desk, customer service, parking lot!" Kai grinned, wrapping his arms around the man. His wings flapped upward, sending both he and the strange Fallen Angel downward towards the ground, head first. Before they both slammed into the ground, Kai let go. His wings spread out, almost instantly keeping him from slamming into the ground like the Fallen Angel.

The man groaned as he laid on the ground, aching all over. Kai stood over the broken man, frowning. "Jeez," Kai sighed. "I had hoped you guys would be more of a challenge. Is everyone so weak around here?" He turned to Issei, who was just now stepping out for the bushes. "How are you, bud?"

"Kai-sensei… what are you?" Issei asked. The man chuckled, shrugging.

"Just a guy who loves to fight," Kai replied, raising his hands up as he shrugged. His eyes were shut, and he had a cheeky grin on his face.

"You will… regret this… Devil scum…" the man grunted in pain. Kai rolled his eyes, turning to face him.

"Yeah, yeah," he sighed. "Go home Fallen- gurk!" Kai's eyes widened as overwhelming pain spread through his body. He looked down at the massive spear of light penetrating him through his stomach. "Well… That's not… fair…"

"Kai-sensei!" Issei shouted as the man fell to his knees. The man in the trench coat glared at the boys.

"Now, with him out of the way… I can deal with you…" the Fallen Angel growled. A blue spear appeared once more in his hands. "Now die!"

"Stop right there!" shouted a womanly voice. From behind the bushes came two lovely ladies. Rias and Akeno, respectively. "If you don't leave my servants alone, I'll be forced to eliminate you."

"Tch… two more disgusting devils…" the man growled, his wings once more spreading as he started to fly away. "While I'd love to stick around and kill all of you, I know when to flee to fight another day." As the man flew away, he stopped for a moment. "My name is Dohnaseek. You best hope that you never hear that name again." With that, the Fallen Angel flew away.

"G-Gremory-san!" Issei panicked, holding Kai's body as he stopped breathing. "What do we do!?" Akeno knelt beside the body and pulled the boy back.

"Let buchou do what she must," spoke the violet haired beauty. "Kai-sensei will be fine. I will take you home, alright Issei-kun?" Rias picked up Kai's body, bat wings springing from her back.

"B-But Kai-sensei…" Issei muttered, not really sure how to process everything that'd happened to him during the last twenty-four hours. "He'll… be ok… right…?"

"Of course he will," Akeno spoke with an uncertain smile, one that went unnoticed by Issei. Rias took off into the air, heading to Kai's apartment. "Just let buchou take care of him. Ah… Issei-kun?"

"Y-Yeah?" stammered the boy. Akeno smiled and took his hand.

"Why don't we go to your house and… relax…?" Akeno spoke softly. Of course she had no intentions of sleeping with the boy. But it wouldn't hurt to humor him just for a little while, just so he wouldn't worry about their teacher. She, in fact, was worried about their fallen [Knight]. While brave, Kai had been foolhardy and let his guard down next to an enemy who was still alive. He was definitely strong, that was for sure, but Akeno wasn't sure exactly how smart the young man was.

[With Gremory Rias]

Rias was lost in her own thoughts as she laid the man in his bed. He was shivering and shuddering, convulsing as his body tried to fight off the effects of the light spear. Rias knew exactly what she needed to do, but she hadn't been expecting to have to do such things with Kai. She had actually expected Issei to be injured, that way she would be able to easily draw him to her side after spending the night with him. While part of her felt bad at manipulating the younger boy, it was an assurance in case things went south. Still, perhaps doing this with Kai would have the same effects. He would be within her debt, and might even come to desire more of her. If that were to happen, then it would mean he'd be less likely to go stray.

The Gremory heiress nodded to herself, stripping herself of her clothes. She glanced down at the man below her, and sighed, stripping the man of his own clothing as well. He wasn't particularly bad looking, but even Issei had some sort of simple handsomeness to him. This man, Kai… He wasn't the most impressive looking man. Still, he was a decent fighter, from what she'd seen. He'd moved at a speed that had taken Kiba years to master, and it was almost on a whim as well. While she knew it was as a result of the [Evil Piece] within the man, the piece's power was dependent on the person's ability to see themselves moving at such speeds, and the piece acting as a correspondent to make such actions possible. In a way, it was akin to faith.

"So then…" Rias whispered, running her hand over the man's arms as she laid in bed with him. "How is it that you have experience moving so fast…? Just who were you, Kai-san?" She stared at his face as her arms enveloped him, pressing her body against his. The pained expression on his face slowly started to fade away, replaced by one of peace and relaxation. The last time she had seen such a face was when her brother would fall asleep at his desk at night, when she was a child.

Rias had a habit of studying people, especially as they slept. She had learned that a person's true face could only be seen as they slept. Who the person was. What they stood for. All of that was shown in their moment of vulnerability. So she studied the man before her. While Kiba, Koneko, and Akeno were all familiar to her and easy to read, Kai was a much harder person to observe. He seemed to have not a care in the world aside from teaching, cooking, and his video games. Yet the smile on his face always hid something behind it. Sadness. Depression. Pain. But for what? The redhead couldn't imagine why. What had happened to him to give him such a mask?

Even still, what she saw before her made her smile. She saw a man at peace, eyes innocent and free from worry. His mouth, opened just slightly as he breathed. It was kind of a cute sight, she thought. While rough and abrasive during the day, he really did have a strong set of morals. She didn't dislike him for questioning her methods. In fact, she was happy that he would go against her in such ways. It meant that he respected her enough not to agree to her constantly. Still, he could do without becoming so aggressive about it.

Rias sighed, actually enjoying the feeling of holding the man. She squeaked in surprise, however, when Kai's arms snaked their way around her waist, and his head nestled itself right below her chin, resting right above her breasts. The man let out a content sigh, moaning softly in his sleep. Maybe he was having a good dream? She allowed herself to reach out to him with her empathetic Devil ability, hoping to get a better read on her mysterious [Knight]. What she felt, however, almost made her scream and run from the man.

There was so much hatred, so much anger that it was overwhelming! But still, Rias pressed on through the first layer of emotions. She could feel something else inside of him. Other emotions. That was when she felt his fear. It was almost like a vast ocean. And it wasn't over a single thing. It felt like… he was afraid of everything. Her. The world. Other people. Everything scared him. She couldn't tell exactly why, but it was there, and it made her sad. Rias couldn't keep up with all of the negativity and let herself withdraw from his emotional pool. She held the man in her arms even tighter, sorrowful at this revelation. While he almost always disagreed with her, and was fairly annoying at times, he was still part of her peerage. Part of her family. To know that he was so angry, and so afraid… It made her sad.

"I'll help you however I can…" she whispered into the ear of the sleeping man. "I promise… I'll keep you safe." While she was certain that he couldn't hear her, a light smile crossed his face as he snuggled further into her arms. It was actually kind of nice. The last time she had done this was as a kid, with Akeno after she'd had a nightmare. Rias let herself relax. Tomorrow, she'd start making everything right. She swore her family name on it!

[The Following Morning]

Rias stretched, yawning as she woke up for the morning. Memories quickly ran through her head. The school day before. Watching Issei on his way home from school. Watching the fight between the Fallen Angel and Kai. Then… taking him home and sleeping with hi to heal his wounds. The redhead blinked, sitting up in bed as she processed the things around her. Sunlight was filtering in through the window by the bed. It was kind of cold, though. Did he have the air conditioner on? Rias wrapped the blankets around her, shivering slightly. She could hear sizzling, and something smelled good.

It took her a moment, but she realized that Kai was already awake, and was standing by his kitchenette table as he was making… something for breakfast. He was already dressed in his clothes for work, and his hands were rapidly moving as he cooked, as if trained by years of habit.

"Morning, Gremory-san," Kai spoke, not even looking in her direction. "I assume you had to heal me last night, hm?" Rias stood, the blankets still wrapped around her as she approached the man from behind.

"Yes," she replied simply, looking at what exactly smelled so good. "Eggs and bacon?"

"I already ate," Kai told her, sparing her a glance. "Nice tits, by the way. However, it's against school conduct for a teacher to have any intimate relations with his students, including and not limited to sleeping naked with one of them."

"You would have died if I hadn't done that!" Rias protested, a bit hurt that he didn't seem to appreciate that fact. She'd saved his life! Her frustration, however, was met with laughter.

"I know, I know," Kai replied as the laughter died down. He stole a plate from the cabinet under the stove, setting it aside and placing the rather delicious looking breakfast onto the plate. "Thanks for that. Now, eat up. I can already tell that today's gonna be a pain in the ass." Rias looked at the breakfast made for her as Kai sat at his desk, supposedly going over student exam papers.

"You seem… awfully ok with all of this…" Rias murmured, starting to eat the food that had been made for her. This was a truly odd situation. She had expected something else, some other reaction from the man sitting before her. Maybe panic, confusion, or something similar? Perhaps even gratitude or even denial? Hell, even him blushing and stuttering at her nude form would have made sense. But this? Him being completely unaffected by his situation? Just who was he?

"You think I haven't slept with a woman before?" Kai asked, giving the redhead another glance. Rias chided herself. Despite how young looking he was, Kai was in his late twenties. Of course he'd have had a few sexual partners. Part of her heart skipped a beat at the thought. Maybe as a last resort… "One, that's kind of insulting, and two, naked bodies don't bother me."

"Really?" Rias asked, almost curious. She knew that he wasn't from Japan, and as such had a looser sense of decency. But to think that nudity didn't bother him in the slightest? "Why would that be?" Kai ignored her question, replying only with silence. "Kai-san."

"Because I'm a pervert," Kai replied, shocking Rias. Such a blunt admission! "Hey, most guys are. I'm a damn big perv, too. I've seen quite a few naked women. However, I have standards." Kai paused as he took a sip from the mug on his desk. "I don't touch girls who haven't given me explicit permission, even if they willingly sleep in the same bed as me." Kai cleared his throat. "I look, but do not touch. By the way, are you naturally bald or did you shave?" Rias' cheeks turned a bright red as she tried to process what had been said so bluntly. While normally she'd be able to tease people with this kind of thing, this was way out of her control! How could she respond to how honest this man was being!? Rias, though, took a deep breath. She reigned in her embarrassment and tossed the covers back onto the man's bed, slowly approaching him from behind. She had to regain control!

"It's all quite natural," she said in a low, slow tone of voice that would have made any lesser man fall to their knees and beg for her to seduce them. "Did you enjoy staring at my sleeping, vulnerable, naked body, sensei…?" she whispered the last few words in his ear, tracing her finger up his arm as she bent over behind him. For a moment, she thought she heard his breathing hitch. Before Kai burst into laughter once more.

"Oh man! Hahaha! That's priceless!" Kai stood, grinning widely as he looked up at the Gremory heiress. "You're trying to seduce me, huh?" he asked, chuckling. "Sorry hun, but that ship's long sailed off. Nobody in the world can seduce a man as manly as I! The epitome of masculinity! But! But," Kai grinned, leaning forward and letting his mouth rest right beside her ear. "If you want to up the stakes…" he whispered, resting his left hand on the redhead's stomach. His palm and fingers slowly started to slide down her body, making her shiver with anticipation, and a little bit of fear. "Just let me know. I never back down from a challenge." Just before touching her most private spot, Kai pulled his hand away and straightened his attire.

"W-Wha…" Rias tried to process what had just happened to her.

"Now then," Kai spoke up. "Finish your breakfast and get ready. School starts in an hour and a half, and you mustn't be late for class. [King] or not, I will punish you if you are not within my classroom on time." Kai walked to the door and pulled on his shoes. "I will see you in class, Gremory-kun." Rias heard the door shut, but she was still shocked. Had… had Kai just resisted her attempts at seducing him and turning him into a stuttering mess? How!? She knew that she was absolutely beautiful! Such a thing would have driven any other man insane! Rias frowned, and rested her chin between her thumb and index finger. A cruel grin befitting Akeno's sadistic smile appeared on her lips.

"If you want a challenge, Kai-san," she spoke to no one in particular. "Then by all means, you shall receive."

Outside, Kai was breathing heavily, trying to hide the erection that had sprouted in his pants. He was damn lucky Rias hadn't noticed, or his entire show would have been wasted! The man grinned to himself, though. It was pretty funny to see her so flustered, though. She was kind of cute, too. Oh well, he had a class to get to. He could worry about the consequences of his actions later.

[Later That Day] [Kuoh Academy] [With Hyoudou Issei]

It was the end of the school day, and Issei was confused. Himejima Akeno, one of the great onee-sama of Kuoh Academy, had not left his side the entire day! Well, at least for the classes that they had together. While he was by no means complaining, he wondered why one of the most beautiful girls in school had decided to take upon his company! It was only made stranger by the fact that she actually remembered that creepy guy with the wings the night before, and how Kai-sensei had gotten hurt! But when he came to school, there was his teacher, just fine and dandy. He didn't even look winded!

"Issei-kun," Akeno spoke up, standing right beside him. Where the hell did she suddenly come from!? A bit shocked at her sudden appearance, Issei calmed himself down. He looked at her with curiosity drawn on his face.

"What's up, Himejima-san?" he asked, trying to play off this conversation as best as he could. He could already feel the glares at him for even daring to speak to Himejima Akeno! Was she trying to get him killed!?

"Buchou would like to extend a formal invitation to you," Akeno spoke in a lighthearted tone. Her smile was soft, but her eyes shone with a serious light behind them. This wasn't an offer he was allowed to refuse. "I have been requested to escort you to the Occult Research Club room." Issei swallowed hard, suddenly feeling like he was on death row. Akeno's expression promised pain if he said anything other than 'yes'!

"I-I'd be honored," the boy managed to stammer out. The eyes of death disappeared from Akeno's face, replaced by an expression of actual happiness.

"Fantastic!" the young lady replied, taking the boy by his arm. "Please, come right this way." Issei did his best to ignore the stares of death that were being shot at him by his fellow classmates. Still, it did nothing to take away from the pure elation of having the Himejima Akeno holding him by the arm! Not only that, but he had the perfect view of her side boobs bouncing as she walked, gravity now becoming his best friend! "Here we are," Akeno spoke to the boy as they came upon a rather large building. It looked more akin to a house than any school building.

"Wow, is this… your club room?" Issei was impressed! They had this entire building to themselves? How did they convince the school to give it to them? And more importantly, how many hot girls were in this club!?

"Yes, it is," Akeno smiled as she opened the door for the boy. He walked inside, looking around. The interior looked like it was ripped out of some rich Victorian mansion! It was definitely kind of creepy, but hell if it wasn't cool, too! Where did all the money for this stuff come from?

"Ah, so you've finally arrived," spoke a voice from further in the room. Coming from a door further in the building was a blonde man, with neatly combed hair and a handsome, pretty-boy face. He had a polite smile, and was dressed in the school's uniform. Yuuto Kiba, the so called 'Prince of Kuoh'. "I was beginning to worry. Everyone else has already arrived. Buchou and Kai-san are in the office discussing future plans. They'll be right out, I'm sure."

"Thank you, Kiba-kun," Akeno smiled, walking further into the room and standing beside a small, white-haired girl chewing on a chocolate bar. The girl gave Issei an impassive look with her yellowish eyes before returning to her sugary sweet treat.

Oh man, and Toujou Koneko is here too! Issei thought with excitement. What I wouldn't do to do that adorable nubile body!

"Issei-kun!" called out a familiar voice. Coming from around the corner of a long hallway was none other than his English teacher, as well as Rias Gremory following up from behind. What the hell was this!? "Ahh, looks like the family' all here! Well, except a certain little bloodsucker, but hey, close enough." Kai was shot a few glares as he stood beside Akeno. Koneko was still sitting on the couch to Issei's left, and Kiba had taken a seat across the table from the little girl on Issei's right. Rias stood directly across the table from Issei, right beside Kai.

"It seems that we can finally get down to business," Rias spoke suavely, as if she had been practicing that line. "Welcome to the Occult Research Club, Hyoudou Issei." Issei chuckled, scratching behind his head with a sheepish smile on his face. "But that's more of a front, than anything else."

"Wait, what?" spoke the boy, confused. "If you guys aren't here for studying supernatural stuff, then what are you guys? In fact, why did Kai have wings!? And why did that one weird guy attack me!? What's going on!?" Issei was beginning to panic. Everything that had happened to him over the last few days was beginning to set in.

"We're Devils," Kai replied easily, bat wings instantly unravelling behind him. Rias shot the man a hard look. "What!? Don't blame me for stealing your melodramatic thunder! That's for trying to seduce me earlier today!" Wait, Kai-sensei and Rias are a thing!? That's not fair! I didn't even get a chance to shove my face between those massive melons!

"As Kai so thoughtlessly said, everyone in this room, including you, are a Devil," Rias sighed, trying to relieve the headache forming in her mind. Of course Kai would ruin her practiced lines like that. It was Kai, after all. At the end of her sentence, she and everyone let their wings unfurl, with Koneko and Kiba standing before they did so. Issei jumped in surprise, garnering an amused look from the young woman. "The ones who attacked you, Dohnaseek and the girl you knew as Amano Yuuma, are Fallen Angels."

"W-Wait, you remember Yuuma-chan!?" Issei asked, getting a laugh from Kai.

"Hey, bud, who do you think made everyone forget about her? Us!" Kai grinned. "Can't have her existing and suddenly disappearing, without a trace, and leaving you high and dry, right?"

"Me, more specifically," Rias sighed. "We, as Devils, are one of three Biblical Factions. The other two are Fallen Angels, and Angels. Originally, it had only been Angels and Devils, but through corruption and sin, some Angels fell and became Fallen Angels, never allowed into Heaven again. We, Devils, have been at war with both factions for a very long time. Fallen Angels are wanderers, and desire to reside in the Underworld, a place that Devils call home."

"And Angels and Devils don't get along for obvious reasons," Kai added. "And again, Angels and Fallen Angels fight for more obvious reasons. So basically what happened was there was a huge 'ol war and lots of everyone died so a truce was called. Right now we have a three-way stalemate between all three factions." Rias sighed, tired of being interrupted. Not only did he ruin her dramatic reveal, but he was simplifying everything so much to take away all of the tension!

"Yes," Rias conceded, realizing that there was nothing that she could say to regain control. It seemed that Kai had won another battle in their game of wit. A wink from the man beside her only proved to her that he knew exactly what he had done. While it filled with her a bit of pride, it also frustrated her. He was supposed to be her piece! She controlled him, not the other way around! It just didn't work that way! So how did he manage to flip things upside down every time he was in the room!? "Now, you have a choice," Rias spoke, shooting a glare in Kai's direction. She wouldn't allow him to cut her off this time. Kai merely smiled and shrugged. That infuriating man!

[Several Days Later]

"So… you and this nun, huh?" Kai chuckled, intercepting Issei after he had helped some blonde girl to find the church in Kuoh. "Not a bad pair. Like a little Romeo and Juliet thing, going on here."

"Wha- Kai-san?" Issei let out a surprised yelp at the voice behind him, facing the older man. "Where did you come from?" Kai chuckled, shrugging.

"Dunno, man. I'm just all over the place," the older man replied, adjusting a pair of glasses on his face. "By the way, do you like my new pairs? Got them today in the mail. The lenses are popped out, but I like wearing them." Issei matched the pace his teacher was walking. "I used to wear these things in my last life. Heh, my eyesight was shitty. I was pretty much legally blind." Kai sighed. "Eh, I kinda missed them. So I got these."

"They… look good on you, Kai-san," Issei replied, not sure what to make of the random conversation his teacher had started. While in public, Issei still called him sensei, but they boy considered the Thai man a friend now. "So… me and Asia, huh? As much as I'd like that, she's a nun. What would happen to her if she was caught dating a Devil like me?" Kai thought for a moment, before snapping his fingers.

"Come with me," Kai said, leading them both in the direction of his apartment. Issei followed, curious to what his friend could be showing him. "So, this isn't really related, but I think I can answer that question for you," he said as they walked. They arrived soon to Kai's apartment, and Issei was invited in. Kai immediately sat at his computer and pulled up a few news article.

"Hey, this is…" Issei immediately noticed the headlines. Miraculous healing? Was this Asia's doing? No, wait… Issei noticed it wasn't Asia in the pictures. It was some other super sexy babe! "What is this?"

"My ex," Kai said after a few seconds, getting a surprised look from Issei. "Yeah… she's a holy woman alright. The strongest there is, and the best there'll ever be." Issei noticed as Kai's expression melted into one of someone lovestruck. For a moment, Issei was jealous of Kai. He managed to find someone he loved without a doubt. But then…

"You said ex?" Issei asked slowly. A bitter smile appeared on Kai's face. He looked back at the pictures.

"As a woman of God- ow, she can't have any contact with me. I haven't been able to contact her even once since I've died." Kai explained. Issei felt bad for the older man. "Still, I know someday she and I will meet again. And when we do, I hope she'll see me as a friend, and not an enemy." Kai chuckled, resting his hand on Issei's shoulder. "You, my boy, have a chance to have something with a sweet, innocent girl. A girl who obviously cares about other people. Whether it's only by friendship, or it blossoms into something more, know that I truly believe in you! As a man, fight for her heart and her friendship, and help fulfil the dreams of a beautiful young maiden! For the oppai!"

"For the oppai!" Issei cheered in return.

[Rome] [With The Mysterious Girl]

"It's been so long, Gabriel," spoke the tan woman. She was a lovely young lady, possibly around her early twenties. She had Arabic facial features, including an angled face with sharp eyes, and wavy, long hair that reached down to her knees. Her eyes shone like gold, however, and her hair seemed to sparkle with hinds of blonde, despite being a dark brown color. Her chest size was large and respectable, and she was easily just under six feet in height. She wore a simple, sky-blue sundress, accompanied by a straw summer hat of the same color with a deep ocean blue ribbon tied around it. On her shoulder rested a small leather purse, brown like the very earth.

Beside here walked a beautiful blonde woman with incredible curves and innocent, yet loving blue eyes. She, herself, was dressed in a beautiful white gown that complimented her flawless peach skin tone. "It's no problem, madam!" Gabriel replied, her voice soft and eager, like that of a child. Yet it held a firm maturity to it. "We all have missed you quite much!" The woman beside her smiled, looking around the beautiful city of Rome. It had been much too long since she had been here.

"Well, I knew that nobody else could possibly give me such wonderful conversation," replied the woman. "After all, those in Heaven have become so stuck up in their ways since I was last there. It's quite sad, really. And Michael was a sweet boy, as well." The woman smiled. "I'll have to ask you to lead in my stead, just for a little while as I continue my search."

"But my lady!" Gabriel protested.

"Please, do not question me on this," spoke the woman. Her voice seemed to echo with power, like the bells of a church after a wedding. Gabriel immediately stopped speaking, lest she suffer the woman's wrath. "He… he is out there somewhere. I must find him before things grow further out of hand."

"Has the Devil not yet returned to signify your request?" asked Gabriel. The woman shook her head.

"No. It appears that he is either busy, or is purposefully ignoring me," replied the woman. "I have warned him of my arrival. Devil territory or not, I will not be kept out of Japan any longer. I will find my beloved, if it's the last thing I do. And no Devil, pure-blooded or otherwise, will stop me from playing my piece."

A/N: Welcome to my new story! I've been planning this thing for a while now, and I'm finally excited to get started! Now then, first things first. Yes, this will all be in mostly kinda sorta third person PoV, simply because of the huge cast of characters I have to work with. First Person is so limiting, and it's one thing that I regret using in Final Chance. Now, I won't go into any of my plans for this story, but yes, the memories are Kai's and will become important later on, and harems will be made. Who goes where? Well, it's kind of up in the air right now so cast a vote! Tell me who (Kai or Issei) should get who, and why. There are only four slots for each harem, so choose wisely. I'll make my decisions on the best arguments made. Also, Issei won't be getting any bullshit powerups in this story. Everyone will be working for their power. Kai is a little bit overpowered in his physical combat right now simply because he's used to moving at high speeds and isn't limited in his imagination. You remember that kid that always nerded out in high school, had a smartass mouth and played a bunch of video games? Yeah, that's Kai.
