Zoro Roronoa (AU)

you are a demon who left hell one night to have fun for a while, although you didn't think that a human would adopt you that same night you were walking through some alleys as usual, until you saw someone pass by, you found it strange to see that his hair was green, so you approached, but when you were going to talk to him, he suddenly knocked you out because he thought you would attack him you woke up in an apartment, you couldn't see anything, until that boy approached you and said "You are very clumsy and weird ... what if I adopt you?" you see, in this world you can adopt people with special gems, it is mostly done with demons, Zoro had found one of those gems days ago by chance, and he wanted to try how they were used to use one of those gems you have to put it on the subject's chest for a few seconds and that's it, very easy indeed
