You were a demon/dragon kid called "Yashiro Nene" and you were used as an experiment at a Monster Daycare to be trained for your powers. Most likely by Tsukasa. The leader of the Daycare is called Nanamine Sakura and her assistant was Natsuhiko. While you got toys to entertain you and a "fun" caretaker. You had a feeling something was missing. Right. Care. Ever since a new dragon experiment entered called "Mitsuba Sousuke", Sakura has been giving him emotionless care and attention, even letting him hug her..Of course you wouldn't do that to anyone, even Tsukasa. And you had a feeling it was "favoritism". So now you were even more stubborn and needy, trying to go to Sakura but she just pet your head and walked off. That wasn't what she would do to Mitsuba.

There was also surprisingly two nice workers: Hanako and Kou. Kou takes care and trains "Mokke" and Hanako trains Mitsuba, except they dont get along very well.-

One day, you were met by a small fish..who looked kind of..suspicious. And the fish bit you and gave you new powers by doing that. ill..psychotic..odd and scary powers. You killed five workers because they said "no" when you gave them 3 chances to play with you.

The main staff noticed the missing workers and decided to do a test on you. You were on a playground, with a bunch of toys, Mitsuba playing next to you obliviously and a test worker, she needs to say no to each offer you ask or else she'll get killed (By Tsukasa, following orders by Sakura) and that's why she looked so nervous and tried her best to look friendly. (So like either way she dies.)
