Disclaimer: First Chapter
Story Start!

"So... Kuroka... the black cat... SS-class criminal of the Underworld... rogue devil... is innocent of any acted simply in the defense of her little sister?"

Serafall wasn't sure how to take that story, it was very believable simply because Kuroka knew of the existence of Super Devils. Nobody outside of those related to the 4 Satans knew about the existence, or was suppose to know at least, that there were Super Devils. Kuroka's knowledge of them, and the fact that two people related to her were trying to artificially create them gave some credibility to her story to say the least. Not to mention, if her story was true then she didn't technically do anything wrong. She had killed her master, but she had done so in order to defend her non-devil at the time sister. Low Class Devils had no real rights, but if Koneko had been a pure Nekoshou at the time, then she couldn't be treated as a slave by Kuroka's previous master. She was protected against experimentation, and it made the fact that they were going to behead the girl at one time all the worse.

Kuroka didn't go mad with power, meaning that Koneko would not have gone mad with power, which was the only reason they were planning on executing her in the first place.

"... I did kill my master, and I killed a lot of people, so I'm not inno... nya." Kuroka ended that sentence earlier than she wanted to. Serafall seemed conflicted between trusting Kuroka, since Naruto trusted her, and doing her job and killing the woman. Obviously, she didn't want to kill her, since she was more than likely innocent of her initial crime. Even the murders she committed after the fact could be considered self-defense, since she was a wanted criminal and people chased after her with the intention to kill her. "... Don't take me away from Naruto..." Kuroka's ears were lowered in worry.

Serafall clenched her teeth a little, unsure of how to treat this situation.

"... I'll talk with the others, tell them this story. Naruto is your new master now, and he's a Demon Slayer that we can't control. I don't know if we're even allowed to punish you anymore since you serve him... or if we would want to." Serafall didn't know anything about this. Usually, Rogue Devils stayed solo until they were tracked down and killed. Peerages were still rather recent, only being a couple hundred years old, and never once has a Rogue Devil actually allied themselves with a human as their servant. It would always be other Devils, since Fallen Angels and Angels would not take them, so they could always just demand the Rogue Devil being handed over. "Killing your master was in defense of blood... and I could possibly call your other kills self-defense. Until I talk with others, I'm going to give you a temporary pardon for your crimes... but you're not allowed in the Underworld anymore." Serafall could give her that much without talking to her fellow leaders.

Kuroka, so long as she didn't enter the Underworld, would not be hunted down anymore. She would be pardoned for her crimes on the basis that the others would agree with her, and Serafall did believe that she had at least one person who would believe the story.

"Naruto cares about her... please don't hurt her." Asia went over to Serafall, and pleaded for her sake.

"If I can't convince the others, then I'll personally ban Kuroka from the Underworld. I'll transform her death sentence into permanent banishment... but either way, you're no longer in danger of death around me." Serafall could promise that much. Even if Kuroka would still be considered a criminal, she wouldn't have to fear death from devils at least. Serafall made no promises from Fallen Angels or Angels, or even Exorcists that were allowed to hunt Kuroka down... but that was only because she was a rogue devil. Anyone was allowed to hunt those down for no reason. "Enough of this, how is Naru-tan doing!?" Serafall shouted with a worried look.

In an instant, she went from leader of the Underworld, to worried magical girl, the transformation was actually a little off putting for Kuroka. At the moment, the usual fun-maker of the group, was feeling a little extra bad at the moment. Her master had nearly been killed, and she had been unable to do anything to save his life. He was only alive because of Shizuku and Asia working together to save him from the poison.

"He'll be... okay..."

"I'm going to go see him!" Serafall got up and started to run towards Naruto's room. Asia wrapped her arms around her waist, and dug her heels into the carpet to try and stop the grown woman.

"He's resting, and being healed still! You can't ruin Shizuku-san's work right now!" Asia did everything she could to try and stop Serafall. The woman was too physically strong for her to stop though. Shizuku stated that she didn't want anyone in Naruto's room while she took care of the rest of the poison, and helped with the blood loss while she was at it. It was delicate work, and Serafall was anything but delicate when she was excited. "You're really strong!" Asia realized that she was just being dragged across the carpet, her efforts were doing nothing.

She was a physically fit girl... but still not a match for Serafall.

She broke into Naruto's room to check up on him, and they could see a knocked out Naruto with Shizuku... and Shizuku was butt naked save for panties, straddling his waist... which he was wearing boxers so sex wasn't happening. She had a cut on the palm of her head, and she was dripping blood into Naruto's open mouth. She was a little more pale than usual, which was odd considering she usually looked like a drowning victim. Naruto was getting more color back to his cheeks though, so whatever she was doing was working well enough.

Kuroka peeked into the room.

"... Really... you can't do this with clothes on?" Kuroka asked with a frown on her face.

"Idiot, my blood contains resistance against all poisons ya know. By infecting his body with my demon blood, his Demon Slayer blood will try to build immunities to fight my blood... and gain all of my immunities ya know." Shizuku was carefully controlling her own blood to soak in through his throat, but not reach his stomach. The process was going to take days, and while Naruto's life was in no more danger, he was still in critical condition thanks to how the poison had left his body.

"Why are you naked though?" Serafall asked the important question.

"I'm going to spend the next few days healing him... I'm doing it comfortable ya know." Shizuku felt comfortable fully naked, or in panties... but honestly she felt more comfortable with no panties on. Still, if she was going to be sitting on Naruto's abs for the next few days without rest, she was doing to get her fill of his body and stay comfortable doing it. She licked the blood off of her hand, before she stuck her tongue down Naruto's throat quickly. "... Now leave... don't worry cat, he's still suffering from blood loss and weak blood pressure... I couldn't fuck him if I wanted to ya know." Shizuku wouldn't be able to make Naruto hard if she tried, so his chastity was safe for the moment.

Serafall went over to the side of the best, and sat at the corner.

"Who did this... who is going to get a firm twinkling?" Serafall asked with revenge in her eyes.

"A very dangerous man, this poison is more advanced than anything you'll see in nature ya know." Shizuku had to fight off the poison, which infected blood cells and caused them to attack Naruto's own internal organs. It was a self-breeding poison as well, meaning once it got inside of the body, it started to multiply until it reached the limits of how much it could breed. The small amount remaining inside of Naruto had used up it's breeding ability, so it wasn't going to grow anymore, but Naruto's infected blood was still at war with itself. "... This poison was made to kill youkai with strong regenerative abilities... this poison has a blessed property that prevents the use of youki ya know. It also causes the very cells in the body to kill the body... Naruto being human actually slowed down the effects of the poison ya know." Shizuku explained with a wince, even her with her poison immunity couldn't help but feel like this would have caused her some damage.

This was a poison, made by a person who would have had to have slaughtered ayakashi, studied them, and then created the perfect poison to kill them with naught bu a scratch. That was dangerous, because this opponent only needed to scratch his opponent once with the right poison, and it didn't matter how strong they were. They would fall.

"I use poison... is there nothing I can do at all to help?" Kuroka asked as she looked down at Naruto. Her own magical specialties were partially based in illusions, flames, and poison. She hated the helpless feeling she had, being unable to do anything to help at all. Serafall actually looked at her in sympathy, since she understood what she would be going through.

Feeling helpless sucked.

"I work better when it's hot and moist, go buy a humidifier and turn the temp up to it's highest setting ya know. He also needs to sweat, since I'm cold blooded I can't help him with that ya know." Shizuku could rub herself against him all she wanted, but unless she was feeling super aroused, her body produced no heat on it's own. She was completely reliant on the heat around her. A hot, moist, space would give her a far more successful work environment to heal in. Asia nodded her head, and she grabbed Naruto's wallet from the dresser. "Not you... Kuroka, you do it... no cat ears or tail ya know. Asia can't read or speak Japanese ya know." Shizuku reminded Asia that she would be useless on her own.

She couldn't go and buy what they needed, so she watched as Kuroka took the wallet, and just obeyed Shizuku... yes, Kuroka was willing to obey Shizuku as she got rid of her cat ears and tails. She turned around and started to walk away from the scene, having what she needed to do. She was soon gone completely, something that Shizuku raised an eyebrow at.

Kuroka must really be desperate to help Naruto.

"I'll turn up the heat then." Asia spoke as she walked across the house to where the thermostat, and she cranked the heat all the way up. Not that she had much of an option but to follow Shizuku's orders, since her Twilight Healing could not grant people poison immunity. All she could do was heal injuries, and fix damage, her power wasn't a magical cure all. So, she came back into the room, and bragged the hem of her dress, pulling it off so that she was standing in her bra and panties. "... I... I have body heat... and I can heal his cells..." Asia walked across the room and got onto the bed, holding onto Naruto and activating her Sacred Gear. With one hand on his heart, and the other on his lower back, she pressed up against him to share her heat.

This was something that Shizuku couldn't do... this was something that she could do.

'... I should just turn him...' Serafall looked down at Naruto with an unsure look. She had the pieces, and she was powerful, she could turn him into her peerage member and strengthen his body enough to get him through this. Still, she knew he would resent her for the rest of his life if she did that, even if it was for her own good. She felt conflicted, since it was very rare she had somebody she wanted to turn. Her peerage was very small because of this fact. "... I can provide heat too..." Serafall decided against knocking the girls out, and turning Naruto. Instead, she simply stripped off her clothes and got into bed with Naruto, holding onto his other side.

Her healing abilities were very minor, but she could provide her own energy, and speed up Naruto's natural healing with it a little. With Shizuku providing him with blood, Asia healing his organs, and her strengthening his dwindling life force, they could help him heal far faster. She didn't have long before she had to go back to the Underworld, so she needed to do what she could for her friend in his time of need.

...

"Shizuku... what is your blood type..."

"Snake ya know." Shizuku didn't have human blood, she had snake-type blood. Naruto had Type-B blood, but her blood was fine for transferring to him, seeing as her blood had both a human element to it and a youkai element to it. Her blood was very trans-formative in nature, but unlike other creatures, her blood had a far higher water content, so it was a very diluted blood. "He'll be fine... ya know." Shizuku didn't sound sure of that statement, seeing as she had never done this to a Demon Slayer before.

Though, there was a possible side effect.

Better not mention it though.
