When Kill Joe was alive he didn't love anyone because his heart was ful of despair.

But after he possesed Haru he became to fell in love by the young dragon little by little. That's why when someone hurts Haru or making him suffer he just end the life of the bad guy.

I guess Joe is kind of yandere, but Haru started to control him to behave good.

You see, I used to put Kill Joe inside that plush doll of his, but I thought would be interesting if he was kind of shadow symbiont. But the plush is still cute so~

Hope you guys like it.
