"So, you used a shiny rock…"

"Gem."

"Okay, a shiny gem that had a description that only you could read on it to summon me from my universe which somehow healed my injuries along with my death from turning myself into a small black hole."

"Yup."

"You have knowledge of many different universe which is how you knew about me."

"That's right."

"And this universe has all the mythologies as reality with you living in a town controlled by devils, who are nicer than they are portrayed as in the Bible, even though you are the descendant of a hero from Christianity."

"True story."

"And this mansion was given to you by the leader of fallen angels who fell from the heaven, not because teaching humans efficient ways to kill each other but because he had sex."

"More or less." I said and Yuki sighed with a defeated look.

"Kid, you got any idea how much money we could make if we used your life as an anime script?" She groaned.

Out of all the possible reactions that I was expecting, she somehow managed to outdo all of them.

"Anyway, you got any other of those gems?"

"Just one. Though the description on it tells me pretty much nothing about who it will summon so I am not exactly sure about using it?"

"What does it say?" She asked with a tilt of her head and I answered with some reluctance.

"…MILF."

"Seriously? Why the hell are you scared of a MILF?"

"Hey, mothers can be scary ass badasses too. And for all I know this could very well be Sukuna incarnated in a mother's body. Meaning I am not scared, I am cautious."

"Bah, to-may-toh to-mah-to, what did mine said anyway?"

"Special."

"Well, that is my grade and I am quite special." She said with a haughty laugh, looking very pleased with the revelation.

"I guess you are." I said with a smile which stopped her laughter immediately as she looked at me with shock before an impish smile appeared on her face.

"Hohoho, slow down kid. You haven't even bought me dinner yet." She said with a laugh. There was only one response to that.

I took a beef jerky out of my inventory and threw it at her face.

"There dinner." I said and walked upstairs, ignoring her howling laugh.

"So, how's the training going?" I asked Aika who was throwing what I assume to be curse magic at the targets we had put in the training room, or the second basement as it was before.

"Good, I think." She said as she hit another target, causing it to burst into flames unlike the last target that had blown up

"There are many different curses, but not all of them are exactly good in combat." She said with a shrug that did some nice movements around her chest area as she created another sphere of magic between her hands.

"Unfortunately the more combat oriented a curse is, harder it is to use them for me. Same for the more complicated curses as well." She said with a groan as she threw the magic sphere in her hands at another target, causing it to freeze.

"Meh, I think you are doing well. Especially if you consider the fact that you were a normal girl not even a week ago." I said with shrug of my shoulders. I might have a small prodigy in glasses here with me.

"Doesn't feel good enough." She said with a sigh.

"Are there any plans? Some sort of plot you have in order to seduce girls and maybe take over the world?"

"What would I even do with the world? No, we don't have any plans for the immediate future other than helping Rias out with her engagement issue. And simply training is enough for that." I said with a shrug. It's not like I was wrong, I might not know exactly where I stood when it came to power but I was quite sure that I was stronger than Riser but even if I wasn't, I could simply grind until I was. The dude's whole shtick was his regeneration, which was definitely an impressive power, but I had powers that could inflict great pain to devils and I was strong enough to be able to beat the guy over and over again until he surrendered.

"Can't believe one of the great sisters of Kuoh is a noble lady trying to get out of her arranged marriage, what kind of a cliche light novel shit is that?" Aika snorted and I chuckled, she had no idea.

"Still, what will we do then? I don't want to just keep training like this, it's not really productive." She said with a sigh and I had a half mind hitting her over the head for that last comment. The girl was getting more proficient in her magics at the pace of a shonen character and she thought that it wasn't productive? Apologize to all the hard working magicians without main character talent!

Not that I would say it but still.

"Hmm, then I guess it would be better to let you have some first hand experience in combat." I said while gripping my chin.

Question was whether I should have her go against a stray devil which I could made into a bonding experience with Rias' peerage or my own dungeons where she could go against a wide variety of enemies.

Or I could…

"Hey, how about you start testing some of your subtler curses on actual living being?"

…help her get revenge.
