Nero: It's a long story....

Flashback mode
"Why couldn't he see I had a point... Demons shouldn't have to kill humans, just for fun, in all honesty we should be friends with them, it benefit us more than us killing them for their blood..." I had just been banished from the demon realm at that time for defending humans from being killed. I am not a yokai, rather a demon or shinigami as you call them, but can still be picked up by a Yokai Watch. I had stumbled upon a human village where we'd normally stake out at. There was only one house that had it's lights on, which I went to. When I arrived, there was a mom reading her little girl a bedtime story, and the girl was cuddling a doll with her, which was Rontao. He didn't change much when I made him into a yokai, all he gained was a human eye. So when the girl was asleep and her mom had left, I entered the doll. When he first came alive, he was pretty excited about it but that changed the next day.

Her parents thought I was a spawn of Satan himself, even though that wasn't the case, and they wanted Rontao thrown out, but the girl wouldn't budge. Apparently he was her best friend and she wouldn't let them throw him out. When he finally got thrown out when his owner was at school , he was bitter towards me.

After that, he checked on his owner every night for a month. That is until one night... I had tagged along with him and he discovered that he'd been replaced.

His emotions were so out of control, I had to take him into Mt. Wildwood in order to protect you all. He felt so damaged, I did the unthinkable. I gave him his magic to turn people into dolls. I was the one who'd started the Mt. Wildwood demon. I thought he'd only use it on one person but I was wrong. He's captured at least 50 people so far, and half should be dead due to old age but his spell, or rather our spell halted their age. He would've gone farther, and if Xe had lost that battle between him, she would've been that last piece to his game. His former owner... I'm glad Komasan calmed him down and helped him channel his emotions healthier.... If you'll excuse me, I have to help Rontao with his shower.
