Demonic Freedom - DxD X Sister New Devil

"Well, for me to tell you that, we'll have to cut some kind of a deal..." Kazuki said with a smirk

"What do you want?" Akame asked, narrowing her eyes at Kazuki

"You see, if it was only you against her, you might have stood a chance against her, but she doesn't work alone anymore. She has joined a supernatural terrorist organization, led by one of the strongest beings in this world, the Ouroboros Dragon, Ophis, and as much of a skilled assassin you are, you won't be able to sneak into a building, full of much stronger supernatural beings than you.

And that's when my deal changes the situation. I will get you into a one vs one situation against the "Ice Queen", while also powering you up, as I'm sure Ophis already gave the "Ice Queen" one of her snakes, making her much stronger than before. And your part of the deal? It's pretty simple..." Kazuki said and took a red Knight chess piece out of a pocket dimension

"I'm sure you know what this is, right?"

"It's an evil piece, right? You want me to join your peerage?"

"Something like that. Not a bad deal, right? You'll get a power-up from reincarnating to a demon, and furthermore, as it's a special evil piece, you'll get another ability. If you worry about getting treated like a slave or anything like that, I can assure you that nothing of that sort will occur to you. So? What do you say?"

"I'll do it!" Akame said without any hesitation

"Are you sure you don't need time to think about it? While I won't treat you as a slave, you're still technically becoming my servant... not that I'm complaining though"

"I'm sure. I swore that I'll do anything to revenge my family, even if I have to become a devil..."

"Demon, not a devil. Now, if you're sure about your decision, you can go to your home, pack your stuff, and go to the mansion on the outskirts of the city. I probably won't be there when you get there, so ask my maids anything you want, and they'll answer..." Kazuki said and teleported away

Kazuki teleported to an apartment, where Lars was waiting for him.

"You're here. So what's going to happen now? Are we going to the Underworld, so you can cast that Master-Servant pact you wanted?" asked Lars

"You know I can't do that, so, unfortunately, we'll have to wait for the next full moon. But don't worry. I'll be keeping my eyes on you, so if you try anything funny, it'll be the last thing you'll try in your life. Now, I want to know who the next person they sending to get Mio?"

"From what I heard, it's Valga. He haven't arrived yet, but soon, he'll get here"

"You're saying his name, like I'm supposed to know him, but I don't. Do you think I know every random demon in the Underworld? I know you because you're strong enough for me to notice and because I heard about your donations to numerous orphanages, but I never heard of this Valga. Is he strong?"

"For your standards, he's weak, but for your sister and her friends, he's strong"

"Well, if that is the case, then there are no problems. Remember, one wrong move, and you're dead. I'll see you around!" Kazuki said and teleported to the mansion

When he arrived at the mansion, he approached Maya and told her that Akame will arrive soon and that they should answer all of her questions as they see fit. Then, he went up to the living room on the third floor and saw Kuroka lazing on the couch, laying down in a provocative pose. He approached her, and gave her a light flick to her forehead, using his finger, successfully waking her up.

"Get up, I need you to do something for me..." Kazuki said as Kuroka sat up slowly

"What do you need me to do nya~~?" Kuroka said in a sleepy tone

"I need you to infiltrate into the castle at Wildart city and teleport all of the contents of my warehouse to the second floor here. The warehouse is under the castle, and you get there through a special teleportation circle in my room"

"But why now nya~~?"

"Among other inventions of mine, the Individual Pieces are also there. If you want me to turn you to my servant, I obviously need the Individual Pieces. Will you do it?"

"I'll do it... it's not like you have anyone else who can do it nya~~"

"Good. It'll be better if you'll go during the night if you want a higher success chance, but I'm sure that a Senjutsu master as you, can easily do it during the day too. I expect to see all of the warehouse contents on the second floor tomorrow morning..." Kazuki said and teleported away

~~~ With Basara ~~~

It was another evening in the Toujou household, with Basara, Mio, and Maria all eating dinner together, after Mio told Maria what happened today at school. Basara didn't mention the talk he had with Kazuki on the roof, as he knew there was a reason why Kazuki didn't want anyone to know that he's alive.

"So Kazuki-Sama visited you at school today!? It's been a while since the last time I met Kazuki-Sama, though, I'm surprised he didn't come to meet you sooner. When the incident six months ago occurred, Kazuki-Sama wanted to come here himself and get you back to the Underworld, but Wilbert-Sama didn't allow him to, saying that you're safer in the human world. I was surprised when Kazuki-Sama agreed to send me to help you, as I was sure that he'll use the chance of Wilbert-Sama's death to bring you to the Underworld...

But, I never knew that Basara-San and Yuki-San both knew Kazuki-Sama!" Maria said

"What can I say? Yuki-Chan and Kurumi-Chan were so cute back then, that I couldn't help but often meet with them! Basara was only a bonus though" They heard a voice say from behind them, and it took them a few seconds to comprehend what they heard, before they turned towards the voice, to see Kazuki standing at the entrance to the dining room.

"I told you we'll see each other quite a lot, didn't I? Now, I assume you have some questions for me..." Kazuki said with a smirk
