Chapter 4: Serafall? Saving a Nun?

"The Sitri Clan. The members of the clan, specializes on water-based magic. Except..." Izayoi was cut off as a pink blur ran passed by him with speed that a Ultimate-Class Devils would have, while he stood still on his spot, as he wasn't phased or affected by the sheer speed of the person itself. When the pink blur ran passed him, he had the time to catch a quick glimpse on the person's face, which he knows pretty well from Sirzech teachings of the Four Great Satans. And he knows that this person was one of them.

"Her..." Izayoi said finishing his sentence, as he saw the pink blur was going straight to the castle before him.

"SO-TAN!" A girlish scream rang out from the castle, as Izayoi raised an eyebrow at the scream. Knowing that it would belong to the person who ran straight to the castle, just a few seconds earlier. Even if the castle was really big and had a massive garden, he could still hear that girl's voice clearly.

"I feel this is going to be fun." Izayoi said as he picked up a pebble from the ground and throws it near the guards, that were guarding the main entrance of the castle. As the pebble hit the ground, causing an explosion to occur, Izayoi vanished out of sight, leaving the guards to scatter around for any enemy attacks.

Izayoi appear in the smoke, caused by the explosion he created, as he looked up in front of the castle doors. "Let's take a look in the castle, shall we?" Izayoi said to himself, with a smirk as he then vanished from sight.

Sitri Household

Izayoi appeared inside the castle, as he look around the castle. The castle of the Sitri Clan was as big as the Gremory's while inside the Gremory castle was decorated mostly with red, from what he heard from Sirzech, the Sitri castle was mostly blue, even the maids and servants here were wearing a blue outfit with the symbol of the Sitri Clan on their chest.

Izayoi then casually walked inside a room, while the maids around the castle look on in curiosity. They were curious on who he is, as they didn't recognized him when he suddenly appeared. But some maids whispered to each other while they giggled, saying that he was a handsome man.

Izayoi looked around the room he was in, it was decorated in blue to signify the Sitri Clan. Izayoi then spotted a jacket hanging over a chair by the table. He then picked it up, and looked at it. It was a royal jacket made for the supposedly King of the Sitri Clan.

The jacket was long reaching till Izayoi's knees, and it was mostly blue, with a little of white along the sleeves. It has golden clips poking out from the high collar, three on each sides of the collar.

"Let's try this on, shall we? The Sitri Clan wouldn't mind if I borrowed this for a bit, right?" Izayoi said with a mischievous smirk, as he slowly put on the jacket. After he put it on, he folded the two sleeves till it reached his elbows. Izayoi then noticed a mirror on top of the desk, as he turns to look at his reflection.

"This doesn't look bad at all." Izayoi commented looking at his reflection, but he then noticed his spiky hair. He then put his hand on top of his forehead and dragged it till the back of his head. After that, he looked into the mirror and finding that his hair was slicked back all the way to the back of his head. He then grabbed a fistful of his hair and positioned it on front of his forehead, adding a little bit of charm to his appearance.

"I look good." Izayoi commented with a smirk, looking at his reflection again.

"Now, to look around the castle and maybe entertain some maids along the way..." Izayoi said with a smirk as he left the room.

Human World

"Where is Izayoi-kun?" Rias asked looking around among the member of the Occult Research Club.

"Izayoi-senpai? I didn't see him at school earlier." Kiba exclaimed.

"Me too." Koneko said while Issei nodded, he too didn't see Izayoi in school.

"I agree with them, Buchou. I didn't see him at school too." Akeno stated as Rias were an unsettling frown on her face.

"He said he'll come to the club today..." Rias said as Akeno look down, a frown appear on her face. Kiba and Koneko think for a while, trying to recall if they ever saw Izayoi today. Issei on the other hand, sit on his seat quietly.

"Buchou," Kiba voiced out as Rias looked at him.

"What is it?" Rias asked in curiosity.

"I've think I know where is Izayoi." Kiba said as Rias's eyes widen.

"Where is he, Kiba?" Rias asked.

"Well, this morning I've met a nun in the streets. She was apparently shock about something. She told me that someone instantly disappeared after they touched a red portal that appeared out of nowhere. She couldn't help but watched it as the person disappeared. She told me that person had blond hair and he wore a Kuoh Academy uniform." Kiba informed her as Rias narrows her eyes at the information.

"Nun? Asia?" Issei in a whisper, knowing who the nun is. "A red portal?" Rias asked as she thinks for a bit.

"Buchou?" Akeno asked.

"The one that have the ability to summon that supposedly teleportation portal would be me. And since Papa and Mama doesn't know him. Then the only one who could do that is..." Rias said as her widen at the realization.

"Sirzech." Rias said as Akeno eyes widen, and so is Kiba and Koneko.

"Impossible. How can Izayoi know Sirzech?" Akeno asked as Rias thinks for a bit.

"I don't know. But I think Izayoi is supposedly in the Underworld." Rias said as Akeno wore a frown on her face.

"What should we do, Buchou?" Akeno asked as Rias look down, thinking for a moment, while everyone watched on except Issei who sits on his chair, confused.

"We should ask Onii-sama." Rias said as Akeno nodded, agreeing with her choice in the matter. But then she realized something.

"Buchou," Akeno said getting Rias attention.

"The archduke sent us a message." Akeno said as Rias crossed her arms below her chest.

"The archduke?" Rias asked.

"Apparently, a stray demon is on the loose in this town." Akeno said as Rias narrows her eyes.

"Then, we'll have to delay our visit..." Rias said with gritted teeth, worried for Izayoi safety. Akeno put a comforted hand on her shoulder.

"Don't worry, we'll find him soon. You know Izayoi-kun, his power shouldn't be underestimated." Akeno said as Rias looked at her with a sad smile.

"Yeah. We'll find him soon." Rias said with determined eyes.

"I hope you're safe, Izayoi-kun." Rias said in thought.

Underworld

"Who is he? He's handsome!" A maid whispered to her friends, which were next to her. They were seeing the new dressed Izayoi, as he walked along the castle, while he looked around with a charming smile.

"Yeah. No kidding." One of the maids answered, agreeing with her.

Izayoi walked along the corridor of the castle, while he had a smirk on his face from hearing those comments about him. While he walked, he sensed the same energy from before, and he turns around to find that the person was running right towards him. Izayoi did the only think he could do, or he wanted to do it since he got here. He pretend to be curious, and when the pink blur was right in front of him, he caught her within his arms, stopping her from crashing into him.

"Hey, are you okay?" Izayoi asked as the girl in his arms, started to shake her head. "Yeah, I'm okay." She said as she look up towards Izayoi, a surprise look could be seen from her reaction. "You know you shouldn't running in these halls, you might hit someone or possibly hurt someone." Izayoi advised as the girl sheepishly smile, while scratching her cheek with her finger to hide her embarrassment.

Izayoi then let's go of her from his arms, while the girl realised that she had been inside his arm, blushed as she step back from him after he released her.

"What's your name, beautiful?" Izayoi said as the girl blushed, while he walk past her. The girl then walk a few step in front of her, and she suddenly fall to the ground, courtesy of the carpet. Izayoi was then greeted with a view of her white panties and her heart shaped butt. "This is really my lucky day." Izayoi said as he stare at the girl's panties longer. He then chuckle, and walked in front of her, kneeling down and held out his hand at her.

"Are you okay?" Izayoi asked again, as the girl took his hand and Izayoi pulled her up from the ground. "I'm okay." The girl stated as Izayoi smiled.

"Have we met before?" The girl asked with a raised eyebrow, as Izayoi shook his head.

"No, we haven't. And thus my question is being avoided." Izayoi said as the girl remembered that he asked her name, but she forgot about it.

"Oh, I'm sorry. I forgot. My name is Serafall Leviathan. How about you? What's your name?" Serafall asked as Izayoi smiled.

"My name is Sakamaki Izayoi." He said with a bow of his head, as Serafall raised her eyebrow never heard of his name before.

"Sakamaki Izayoi? I've never heard of that name before in the Underworld." Serafall said with a hand under her chin, thinking back on his name.

"Well, that's because Serafall-chan, you haven't heard of me before." Izayoi said as Serafall look up in front of her, seeing that Izyaoi disappeared out of sight.

"And I think I have overstayed my welcome in this castle." Izayoi's voice said as Serafall look around but she can not find him, but then she look behind her to see a glimpse of Izayoi's shadow leaving to the way of the exit.

Serafall narrows her eyes, "You will not leave here without answering some question, stranger." She said as she rush towards Izayoi.

Just as she rounded a corner, where she spotted Izayoi's shadow, she immediately spotted Izayoi walking leisurely along the halls.

"And if you don't answer the questions, then you will not leave without suffering a minor injury along the way." Serafall said as a ice wall suddenly appear in front of Izayoi.

"Ice, huh?" Izayoi stated himself as he then raised his hand, and curled it into a fist as he then punched the ice wall, which prompted it to explode into tiny pieces.

"What?" Serafall asked herself, shocked that Izayoi easily destroy the wall of ice.

"Shock? I've heard that a lot." Izayoi exclaimed turning around to face Serafall.

"Who are you?" Serafall questioned with narrow eyes.

"To answer your question, the name's Sakamaki Izayoi. And to shed a little bit of light to your confusion. Do you know Sirzech?" Izayoi suddenly asked as Serafall raised an eyebrow on his question.

"How do you know Sirzech?" She asked.

"Well, it was easy to defeat him. It wasn't that hard though to beat him, despite, he was a Ultimate Rank Class he was using his Power of Destruction nonetheless, but as I said it was kind of easy to beat him." Izayoi stated with a shrug, as Serafall widen her eyes, finally piecing out the pieces together, on how Izayoi knew Sirzech and how Sirzech had gotten those severe injuries. The person who had defeated Sirzech, was rumored to be extremely powerful, being able to defeat Sirzech with ease, without any injury as stated by Sirzech who told them, that the person left unscathed.

"So you must be the one..." Serafall asked as Izayoi smirked bowing his head.

"Yeah. I'm that person who defeated Sirzech." Izayoi said.

"Then, nice to meet you!" Serafall said suddenly as Izayoi raised an eyebrow at her.

"Why the sudden change of reaction? Sera-chan?" Izayoi said with a smirk, as Serafall's heart skip a beat.

"W-Well, Sirzech told me that this person wasn't to be played with or underestimated with. And I believe him for the most part, but I never known that you were..." Serafall said as she slowly walked over to him, while Izayoi raised an eyebrow at her unfinished sentence.

"That I'm what?" Izayoi asked, as suddenly Serafall hugged him, her breasts pushing against his chest.

"That you were so cute! And extremely handsome." Serafall said the last part in thought, as Izayoi kept his arms around her to stop them from falling to the ground by now, which thankfully they didn't. Izayoi then chuckles at her compliment of him being cute.

"What so funny?" Serafall asked with puffed out cheeks, looking up at him with big blue eyes.

"Nothing. But thanks for the compliment, but I never known that I was cute..." Izayoi said leaning his face towards Serafall, who could feel his breath against her, which send chills down her spine, and she like it.

Serafall then snaked her arms around Izayoi's neck, her childish demeanor vanished, as her eyes had that seductive glint on it. "Well, it has a little truth that your were cute, but I was actually hiding the real truth about what I think about you." Serafall said as Izayoi smirked.

"And why is that?" He asked.

Serafall then leans up towards Izayoi, leaning closer at him, as she stop just short distance from touching his lips.

"That the person who beat Sirzech would be extremely handsome..." Serafall said as she then peck Izayoi's lips with hers, and then she pulled back, her childish demeanor coming back, and she had a blush on her cheeks.

"I never thought that Leviathan would be so straight forward." Izayoi said with a sly smirk, as Serafall turn her head away from him to hide the heating blush on her cheeks.

"But I don't care." Izayoi said as Serafall turns to look him.

"Really?" She asked.

"No. I do care, but I don't mind cause I've been kissed by someone as beautiful as you." Izayoi said with a sly smile, as he then leans down at Serafall pecking her nose, as he look at Serafall, who had a visible pout on her face.

"Were you expecting something other than that, Sera-chan?" Izayoi asked as Serafall look at him, and blushed.

"No..." She said, as Izayoi smiled, thinking up a plan to make her happy.

"Well, if you want to get something you want, you have to first give me something in return." Izayoi proposed, as Serafall look at him, interested on his offer.

"Because I suddenly arrived here, due to a 'stupid friend' that I want to punch. So, I'm stuck here until I get to return to the Human World." Izayoi said as Serafall wore a smile on her face, feeling happy that he would stay here, but it was because he can't somehow, but she ignored it and continue to think about the offer he proposed.

"Well, how about a tour around the Sitri Clan?" Serafall asked as Izayoi thinks about it.

"Okay. I would like to take a tour around the Sitri Clan. But I want to meet a certain 'stupid friend' at one of our meeting place. He would have some explaining to do, before I have to beat him up again for doing this to me." Izayoi said as Serafall raised an eyebrow.

"Why?" Serafall asked as Izayoi sighed, bored that he would have to explain her all the details.

"Well, I'm a human, Sera-chan." Izayoi answered as he look at her reaction of his declaration. He saw that she had a confused look on her face, while she stared at him with her blue eyes. Who was he kidding? No mere humans could beat a devil easily, more or less even touch them if they decide to fight. And for his part, he was a human and he beat Sirzech, a Ultimate-Class Devil and he left unscathed, without any injuries.

"Human?" Serafall asked as Izayoi nodded.

"Yeah. I'm a human. I'm not even a devil. I'm just a normal human." Izayoi answered.

"But you have powers that no normal humans possessed. I mean, you beat Sirzech easily." Serafall said as Izayoi sighed.

"I was born with it." Izayoi stated

"Are you really a human?" Serafall asked looking up at him.

"Yeah. I'm a human." Izayoi exclaimed as a smile appear on Serafall's lips, remembering the times with Izayoi, even if it were short. But it was fun for her. And she realized that she doesn't care about whether Izayoi was a human or a devil. She just wanted to be with him, and that is her choice in the matter, in spite of her father would question her soon, about her feelings for Izayoi. But she didn't care, as long as Izayoi is with her, and by the end of this day she will get a kiss from him.

"Then, I don't mind." Serafall answered as Izayoi raised an eyebrow.

Serafall then extend her hands out to Izayoi, and caress his cheeks in her hands. "I don't care if you're a human. But it's a shame that humans aren't as handsome as you." Serafall said as Izayoi smirked and grabbed her hands with his hands.

"Is that a compliment? Or an insult?" Izayoi asked as Serafall smiled.

"A compliment. But if humans are as handsome as you, I would still picked you regardless of them." Serafall stated as she let go of her hands from his cheeks, while Izayoi smiled.

"Then, how about we start this tour?" Izayoi asked as he turns away from her and walked ahead of her.

"But how will you return to your own world?" Serafall asked catching up to him.

"You can transport me back, right?" Izayoi asked with a smirk.

"What if I don't want to? What if I want you to stay here?" Serafall asked with a seductive smile, standing in front of Izayoi to stop him from walking. Izayoi look at her, as he put his right hand on her shoulder, and leans closer to her.

"Then, you don't get your gift you wanted." Izayoi exclaimed as Serafall remembered his offer.

"You're no fun..." Serafall stated with a pout.

"But you still get your gift you've wanted, when we're finished with the tour. And when you'll transport me back to the Human World." Izayoi said as Serafall suddenly smiled, wanting Izayoi to kiss her like she wanted.

"Then, what are we waiting for? Let's go!" Serafall exclaimed excitedly as she grabbed a hold of Izayoi's hand, and pulled him outside the castle, scaring the guards as they saw Serafall with a boy her age, as the two begin their tour around the territory of the Sitri Clan.

Everyone in the castle and outside the castle, wouldn't forget Serafall's smile on her face, as she dragged Izayoi all over the place to the interesting parts of the Sitri Clan's territory.

Gremory's Household

"Ugh.. Why am I getting the feeling that I'm going to be punch?" Sirzech asked himself as he then shrug, completely forgot that he summoned Izayoi to the Underworld for fun.

Human World

"What a strong murderous intent!" Issei comment feeling the strong intent from inside the church. He and Kiba were hiding behind two trees, while Koneko hid behind a bush.

"There must be lots of priests gathered." Kiba commented with a smile, as Issei turns at him with a smile.

"Really?! I'm so relieved you came with me!" Issei stated at him.

"We're a team, after all!" Kiba said with a smile, but then he narrowed his eyes. "And personally I'm not overly fond of fallen angles and priests. I despise them." Kiba mutters as Issei held a concern look.

"Kiba?" He asked.

Then, Koneko stood up, attracting Issei's attention, "Huh? Koneko-chan?" He asked as he look at Koneko who stood in front of the church's door.

"They must've noticed we're here anyway." Koneko informed him, as Issei and Kiba came up to her, as Koneko kicked open the door, allowing the three to look inside. The three step inside the church, while looking around the messed up place. Statues being destroyed, the cross which was held in front of them was destroyed also.

"This is terrible." Issei commented, as he, Koneko and Kiba were greeted by Freed, "Hey!Hey!Hey! We meet again!" He said walking over to stand in front of them. "I'm getting sentimetal." He commented.

"Freed!" Issei shouted.

"I never thought I'd meet the same demon twice. You know I'm super strong, so once I meet one of your kind he gets this treatment." Freed stated dragging his hand over his neck. "That's why I'm pissed." Freed said as he unsheathed his sword and gun.

"About you demon trash hurting my pride!" Freed said as he licked his gun.

"Where's Asia?" Issei asked.

"Oh, the junk sister who fell for a demon?" Freed said turning his head away from them.

"She's at the underground ritual site you can reach through that altar." He said.

"Underground, huh?" Kiba said.

"Well, if you can get past me, that is." Freed said turning to them.

Issei held up his hand in front of him, "Sacred Gear!" He said as a red gauntlet appear on his hand, while Kiba held his hand around his sword's handle.

"Well, come at me!" Freed provoked, as Kiba charged towards him, with Issei following behind him.

Underworld

"It's getting late." Izayoi commented looking up, seeing as the sky took on a dark color, meaning that it was night.

"And I have a bad feeling about this." Izayoi said as Serafall who still held his hand, look at him in confusion.

Izayoi then look at Serafall, "Sera, could you transport me back to the Human World?" Izayoi asked as Serafall's eyes widen, not expecting the day to end this quickly.

"But how about the gift I wanted?" Serafall asked as Izayoi smiled.

"You'll just have to wait. But I think it's time I got back home. Rias, is going to be worried about me." Izayoi said as Serafall raised an eyebrow.

"Rias? You mean Rias Gremory?" She asked as Izayoi nodded.

"Are you in her peerage?" She asked as Izayoi shakes his head.

"No. I don't want to enter in early. Or else I'll have to deliver boring deliveries for her." Izayoi said with a wave of his hand, as Serafall giggled.

"Well, it's okay. And I think I borrowed your time long enough." Serafall said as she held up her hand and aimed it at her right side.

"It's nice to meet you, Izayoi-kun." She said with a smile, as Izayoi nodded in agreement.

"It's nice to meet you, too. I have fun today. Even more that I had skip a whole day of school." Izayoi said with a grin, as Serafall smiled. She then look in front of where her hand was positioned, as a blue portal suddenly appear at her will.

"Nice portal." Izayoi commented looking at the blue intricate portal.

"Thanks. But where do you want to go?" Serafall asked as Izayoi thinks for a bit.

"Well, can you transport me to a certain person?" Izayoi asked as Serafall nodded.

"If you can remember her, of course. If you can touch the portal, and think about the person. And then the portal will transport you to him or her." Serafall informed him, as zayoi in understanding as he walked over to the portal. He slowly held out his hand to the portal, and touched it. He then began to start thinking about the nun he met in the morning in the Human World.

After few seconds, Izayoi pulled away his hand sensing that the portal would now transport him to the nun.

"Well, I guess this is it." Serafall said as Izayoi look at her, knowing that she didn't get the gift she wanted.

Izayoi then slowly walked over to her, "I'm not too sure about that." Izayoi commented as Serafall look up at him, and was surprised as a pair of lips were on hers. Serafall then slowly get over her shock, and she begin to kiss back, to which Izayoi held a smile under the kiss.

Slowly, the two pulled back on the kiss, "Have I gave you the gift?" Izayoi asked with a smirk, as Serafall look up at him and nodded.

"The best gift ever. I loved it." She said with a smile as Izayoi pat her head with his hand.

"I'm glad you love it. It was a fun time." Izayoi said as he turns away from her and begin to slowly move towards the portal that was waiting for him.

"Ja'ne, Sera-chan." Izayoi stated as he glance behind him, and offered her a smile, to which Serafall respond by waving her hand at him. Izayoi then touched the portal, as it suddenly glowed blue and suddenly he and the portal disappeared.

"Bye, Izayoi-kun..." Serafall mutters with a smile, as she put her hand on her lips.

Human World

"Asia!" Issei shouted as he run towards her, "Hyoudou-kun, wait!" Kiba said grabbing his arm before he ran, as a spear of light suddenly pierce the ground in front of them, as it then exploded, sending Issei and Kiba to the wall behind them.

"What are you doing to Asia?" Issei asked.

"I see! The fallen angel's objective was to..." Kiba said as Issei gasped, while Koneko glanced at Kiba.

With Rias and Akeno

"I see. so the fallen angel intends to take the nun's Sacred Gear." Rias explained as she look up at the three fallen angels above her.

Back with Issei...

"Take her Sacred Gear? What'll happen to Asia? That's..."

With Rias and Akeno

"Then, the owner's life will be..." Akeno said

"Asia is going to die?" Issei said with a shocked look.

"Your Twilight Healing is finally in my grasp." Raynare said holding her hands up to reach the two silver rings with a blue-green gem on each ring. Just as she went to take the pair of ring, she was interrupted as something or someone crash landed above her, as debris and smoke covered the area.

Issei held out both his hand to shield him from the sudden appearance of smoke, while Kiba shield himself with his sword. Koneko on the otherhand, stood still on her spot as she sees a silhouette in the smoke.

After the smoke resided, the three of them look on, as Raynare was suddenly on the ground, unconscious in a crater. "Did I miss anything?" A voice said as Kiba and Issei held shocked looks except Koneko who had a small smile on her face, as the three saw Izayoi standing on top of Raynare, while he grabbed the pair of rings in his hand.

"Hi. Looks like I have to save the nun." Izayoi said turning his head halfway to look at them, greeting them with a smile edged to his face.
