Probably around 2008 I started reading a manga, forgot the name of it, and have never been able to find it since. I think about it every once in a while... 234k2g

Basically there's this kid who turns into a cannibal because there's this voice in their head telling them to. There is something about a cherry/plum blossom tree, and something about the more people they eat, the more petals it gains. Sorry, 7 y/o memories aren't that great...

Perhaps this rings a bell for anyone? Thanks for any help!

maybe its Kurozakuro?

Ah, yes! Thank you! 🙂
