Hearing the door at the verge of being smashed in, Obsidian Noir grumbled as he got dressed into his jeans and a black hoodie, having a slight suspicion what was going to happen.

Given that he made a good deal in selling a house and finally had some alone time after some...excitement, one could say that the day was going really well.

Too well, so the man could not say he was surprised at the noise in front of his house.

When equipped in proper clothing, he opened the door. The sight somewhat surprised him.

Somewhat, because he would expect Issei being here. He came every two days, though he looked way more panicked and serious than normal porn would warrant.

What surprised Obsidian however, were the two other students with the newly reincarnated devil.

The newcomers both wore the Kuoh high school uniform just like Issei. One was a blonde teenager with a face one might call handsome. Though that handsomeness was strained by the look of confusion pointed at the adult.

The other one was a petite, white haired girl, blankly staring at Obsidian. Lolicons would call her a dream coming true.

Luckily, he wasn't a lolicon. At least now. The past might have been different, but he didn't quite remember.

Both of them were devils themselves. If the man wouldn't know any better, he would think that he owned them a soul or two.

Not like he hadn't souls in masses, but that wasn't relevant.

The girl's eyes widened slightly as she sniffed the air and the Vietnamese sweated a bit nervously. After a while, the small girl frowned and Obsidian let out a mental sigh of relief.

It was a good decision to wash himself more thoroughly than usual.

"I need your help to save Asia!" Issei exclaimed suddenly and Obsidian closed his eyes as if he was in pain.

"Damn you Murphy..." He exhaled a lot of air before opening his tired eyes. "What happened? It's only been a day."

"Issei, who-"

The handsome one was interrupted when the wielder of Boosted Gear grabbed the Vietnamese hand with determination.

"I tell you while we go! She is in danger."

"Okay then." Sid cracked his neck after a slight pause, groaning a little, before putting up his hood, shadowing his face. "Let's go."

"Issei, I am not sure we should do this. Is he able to handle himself?" The blonde one asked uncertain and the small girl nodded, wondering the same.

"He can use Magic and is hella strong!" The pervert exclaimed proudly.

"I'm more average. But worst case scenario, I know people that can help us," the adult stated as he scratched the back of his neck awkwardly, not used to the praise. These words however, cheered the dragon user even more and he hugged him tightly.

"I love you, buddy! Thanks!"

"Yeah, love you too," Sid said as he patted Issei and returned the hug with a small smile.

While ignoring the weird looks he received from the two other teenagers.

Was Issei that bad at school?

With that exchange over, the quartet began to run towards the church a few blocks away. At first they traveled in silence, but then the adult extended his arms towards the two students he didn't know, without missing a step or looking at them.

"By the way, Obsidian Noir. Nice to meet more non crazy devils."

"Yuuto Kiba. Likewise...I guess," the handsome replied, shaking the hand in confusion.

"...Koneko Toujou." The little girl on the other hand didn't take the hand and instead bowed her body slightly before focusing back on running.

Without changing a single muscle in her face.

"Pleasure." The adult put his hand into his jean's pocket and pulled small package out. He presented it to Koneko. "Want a biscuit?"

After pausing for just a short moment, she took one and started to nibble on it. Then she raised her thumb and a small sparkle appeared in her eyes.

Approval.

The hooded man chuckled warmly.

Just like an adorable, not hyperactive cat.

"Alright, we are going right now. What happened?" Obsidian questioned when he caught up to Issei and turned his head to him, who flinched at the memories. Resignation on his face, he recounted the events for him.

About the stray devil hunt and the explanation of peerage pieces.

About how he encountered Freed Sellzen, who ambushed him at the summoning ground and only got saved by Asia, who served as a distraction until Rias and the others arrived.

And how he spend time with the nun the next time, promising to be her friend...Just to get ambushed again, this time by Yuuma Amano, whose real name was Raynare.

Just to get saved by Asia again.

Obsidian grunted impressed in face of all that information.

"Well shit, that is a lot..." Unamused, he frowned at the pervert. "Seriously though, you really got rusty. I mean...two times getting your ass kicked?"

"See? I told you. But noooo, you just had to jerk off to porn," Ddraig complained, his voice sounding inside the heads of the two friends. Issei in turn glared first at his left hand and then back to Obsidian.

"Sorry I don't pick fights with super monsters left and right!" After the exclamation, he let out a deep sigh. "I guess I have to get back into Pre-you-know-what state, huh?"

"Yeah. In the past, you could have smelled those surprise attacks miles away, but now...geez. First thing you gotta do his getting your touch for it back. I'll send someone to watch over your training," the older man stated with a wry smile, shaking his head.

"But it's so boring!" The self-proclaimed harem king complained, causing Obsidian to frown.

"Do you want to have holes in your body again or not?"

"Ugh, fine..." Issei sulked. Seeing him acting like a child, the Vietnamese tilted his head slightly in order to listen the two other devils, slightly trailing behind.

Straining his ears, he got some bits.

"...t they are talking about?"

"...no idea."

No hearing anything interesting, he shrugged and focused back on running.

/

A while later and they arrived in an alley with a good view on the church. While Obsidian took watch, he listened to the planning going on behind him.

"The front door would be the quickest way to reach the sanctuary and through that the living quarters. That's where Asia probably is," Yuuto explained and the Vietnamese heard some paper unfolding from his back.

"Why do you have a blueprint from the building?" Issei asked flatly and the man chuckled amused.

Always had to focus on the small stuff.

"It's the basics when you assault an enemy base," the handsome devil said happily and even the Vietnamese could feel the sparkles behind him. Naturally, the unpopular boy made an annoyed noise.

This was his cue to turn his head around slightly as he leaned against the wall.

"Okay...how are we going to do this? Cardboard box stealth, Metal Gear Solid style? Or CS:GO P90 rush?"

At first he received blank looks, as the references went over their heads, making him sigh at their uncultured nature. But Issei quickly shook his head and yelled impatiently:

"The one that gets us the fastest in there!"

"P90 rush it is."

With those disappointed words, the quartet quickly ran towards the gate, which got swiftly broken by Yuuto with one of his swords. But as they neared the actual entrance, Obsidian abruptly stopped and groaned.

His senses told him that complications already arrived.

"What's wrong?" Koneko quietly asked him as the rest stopped.

"Fallen angels," the oldest of them replied dryly and began to crack his fingers. The small girl's eyes widened and sniffed the air. She immediately turned to Obsidian suspiciously. Not waiting for their shocked faces to disappear, he sternly glared at them.

"I'll handle the two of them." Before any objections could arrive, he send a look at Issei. "Go safe your girl." A small grin appeared on his face and a growl sounded in his voice. "Don't worry. Nobody will escape tonight."

There was still hesitation in their body language, as they send each other uncertain looks, but it is the wielder of Boosted Gear who gave him a hard slap on the shoulder.

"Alright, but don't you dare die!"

With those words, he rushed into the old building, followed by the two other students after they told him good luck. He snorted when they were gone and closed his eyes to focus. Still, a stray thought wandered in his head.

Amusing.
There weren't many things that could kill him.

Just as the trio left him, he could hear the sound of wings unfolding. Casually, Obsidian stretched his arms as he opened one eye to see into the sky.

Witnessing two beings with black wings. One was the definition of a blond, twin tailed, small gothic lolita, a sadistic grin on her face. The other was dressed in a very skimpy, red secretary outfit, showing off her big cleavage. She was the one who spike first, as she shoved some of her long blue her from her face.

Her voice was full of arrogance.

"Pfeh, a mere human trying to face us?"

"Sixty four," the hooded man counted bored as he began to stretch his legs as well.

"Foolish mortals like you should know their place. But it is fun to see you struggle in vain, hehe!" The smaller devil giggled, twirling a pink light spear around in her hand.

"One hundred ninety two," Obsidian counted again, finishing up his stretching with his arms. Then he shook his body, jumping on one stop in a rhythmic manner.

"And-What are you doing?" The busty one questioned annoyed, after realizing that the man in front of her was not even remotely scared. Bored, said man looked up at her, shoving his hands into his hood pockets.

"I have a mental list of stupid one liners I heard from evil guys. And I'm not impressed," he explained and his mouth corners twitched a little.

The two fallen look at each other in silence. After a while, they both nod at the same time.

"You know what? Fuck it, let's just kill him!"

"Agreed."

"Huh, twenty two."

This final count led to the two woman growl in frustration and both threw their light spears at him. They traveled at inhumane speeds towards the mortal who insulted them and kept insulting them by keeping his eyes closed. At the velocity the weapons were going, it was impossible for the man to dodge.

To his defense, he didn't dodge at all.

Instead, he softly sighed...and shot his arms up, just in time to catch the spears, as they were about to pierce his face and heart respectively. Their tips almost touched his hoodie.

Almost.

By now, a white light radiated from his body, sizzling against the spears. His usual brown eyes glowed in a small blue light.

The shock the two females expressed could be compared to a thunder running through their veins.

"You are not the first fallen I killed," the human stated coldly as he clenched his fists, crushing the holy weapons into non existence. "Also, I want you to meet a friend of mine. She doesn't like you ripping of her style..."

The two fallen angel instantly raised their guard, looking around in order to spot that 'friend'. Meanwhile, Obsidian raised his hand...and snapped his finger.

"Summon."

All of a sudden, another person appeared next to him out of nowhere.

There was no warning, no magic seals or similar that could have foretold the newcomer. One moment she was not there and in the next she was.

Sweat ran down on their faces, not comprehending what was happening at the moment. That meant a lot, given that most fallen are at least centuries old.

The new person was bizarre. A young, short black haired woman, one head smaller than Obsidian, saluted as she was dressed in a white shirt and a black skirt, an easy going smile on her face.

Overall, she looked like a school girl.

If it weren't for the black wings on her back.

Many would mistake her for a fallen, just like his opponents.

But Obsidian was fully aware that she was one hundred percent Japanese, ergo, not a fallen.

"Kazuko, reporting for duty!"

The man simply nodded at her and pointed at the two opponents in front of him, making the girl follow his fingers.

"Lettuce?" The left finger was raised at the lolita. "Or melons?" The right finger was raised at the busty one.

The girl at his side hummed in thought as she tapped her chin. In the end, her smile becomes more cold when she looked up to the right.

"Never had melons, so I take that!" A small giggle escaped her. "Can I play around with her~?"

"Sure. I was planning to use mine as training dummies anyway. Getting to move my body a bit," Obsidian stated relaxed as he shrugged.

These words shot off the battle.

Immediately, Kazuko took to the sky in super sonic speed as she made a strong gust with her wings. Slamming her right hand into the blue haired ones face, she began to drag the fallen woman away from the church. Obsidian only saw how her left hand moved under her clothing in the chest area and pulled out a bladed fan before she went out of sight.

One problem dealt with.

His attention turned back to the lolita, just in time to duck away from another light spear sent at him.

"T-this means nothing! I still have the advantage!" The fallen exclaimed with anger, charging up another holy weapon in her hand as she floated in the sky.

The man didn't deign her with a reply and instead exhaled slowly in a relaxed stance, with his hands back in his pockets.

Then he stomped on the ground, burrowing his right foot into the earth and shot his leg upwards. This action caused a small shockwave, which in return send masses of dirt up in the air. The corrupted being tried to dodge out of the way, but the scale of the substance sent at her was too big and it hit her square in the face. It didn't do any real damage, only slightly shoving her up in the air a little, but her senses were sullied.

Literally.

As she rubbed her eyes in pain and spat out dirt, Obsidian didn't miss the chance. He walked towards the forest in a quick pace, hugged one of the trees and lifted it with gritted teeth, ripping it out of the earth.

With the natural weapon in his arms, he jumped.

When the brown girl managed to open one eye, she was ready just in time to feel said tree smack her in the face, towards the ground.

After she spiraled down, a loud crash sounded on impact, followed by a soft thud from the man's more graceful landing.

He raised himself slowly and dropped the tree. After he cleaned of the dirt from his hands, he put his right hand back into the hoodie pocket, while the other was at his side, clenched in a fist. And he waited in front of the fallen's body, head stuck inside the small crater.

A muffled scream of rage later and pure holy energy was released from her body as she ripped her head out of the earth.

Her aura cleaned off her entire body and her visage was distorted in pure vengeance, raw power sparking in her hand as her anger materialized two light spears at once.

"You...are...dead!"

Her roar actually shook the earth, scaring off the animals that didn't fly away yet.

Despite that, Obsidian stood there, impassively.

"I stopped counting that one after it passed the triple digits," he stated with a raised eyebrow.

This tore the final line of patience the fallen had left and cried out as she rushed at him, intending to ram the spears inside his bodies.

Switfly, she stabbed with her right spear, which he dodged with a head sway. Not discouraged by that, the fallen roared and tried to swing the other one towards his stomach.

Tried, because before she could finish the movement, his left fist burrowed itself into her stomach.

A power no normal human could have, made her spit out blood as her inner organs got squished by it and send her flying. With pained gasps, she looked at the man who softly blew on his fist and then rubbed them on his body to get her stench off it.

Anger bubbled up again and she intended to summon up another light spear.

Despite her intentions, Obsidian calmly walked over her, slowly revealing his right hand.

Holding a transparent, silvery dagger. It didn't look like it had any substance to it, its form slightly shifting like under water.

He was calm, because he already won. The face of fear and shock on her face told him that the girl realized that as well.

Frantically, she looked at her hands and moved them in panic.

Nothing happened.

"W-what did you do to me?! Why can't I use my light?!" She yelled, trying to back off, only to hit a wall.

"I disrupted the flow of your aura inside of you," the Vietnamese explained patiently as he eyes his personal weapon, after which he stared at her with a small grin. "Senjutsu 101."

"H-how can a mere human…?" She began to stutter, but stopped when she took a closer look at him. Eyes widened with realization and a shaky finger was pointed at him.

"Wait a minute...You aren't human! You are a hom-"

She never got to finish the sentence.

Having gotten close enough, Obsidian casually stabbed the knife into her throat, replacing her words with pained gargling as blood escaped her. In vain she grasped his hand, firmly holding the weapon.

But he did not let go. With a cold look, he observed her as her life force escaped her. Slowly, as her eyes became misty, he leaned in to her ear and whispered.

"That's rude. I'm as human as it gets."

With that said, he pulled the knife out and wiped off the blood on the clothes of the corpse. Hearing wings flutter behind him, he turned around calmly…

And backed off in disgust.

Kazuko was back, a wide grin on her face.

Holding a bloodied fallen in her right hand.

Bloodied being an understatement.

The previously good kept her was scattered all over her swelled and red beaten face. Her clothes barely existed on her body, as it is full with cuts and wide gashes, blood dripping from them to the ground.

And she was still breathing.

"Eww. Seriously? You couldn't just kill her?" Obsidian questioned, shaking his head in disgust.

"I thought you wanted to expand your collection," the girl giggled, sheepishly rubbing the back of her head.

"I already have-" He stopped his own irritation by closing his eyes and taking a deep breath. That done, he groaned. "This is such a pain...Fine." Quickly, he stabbed his dagger into the woman, who gasped in quiet pain, before slumping down as well after a while. "Going to deal with them later."

As he muttered that, he cleaned off the weapon, again, and turned to the only girl with bird wings that was not a corpse. She folded her hands behind her back and giggled for a moment before she leaned forward playfully.

"Anything else?"

"Nah, you can go now." After Obsidian waved her off, she saluted yet again and vanished as she appeared.

With no warning.

The man cracked his neck when she disappeared and let out a loud yawn.

Why did this always happen in the night?

Nonchalantly, after he was done with his neck, turned towards the forest...and bowed graciously, right arm moving into an L form in front of his chest.

"And how are you tonight, Miss Gremory, Miss Himejima?"
