what's this? what's with the altered name? It's my avvie in certain places to distinguish myself from other Eirin players. There's always a joke about the "Old Ladies" in Touhou bristling about cracks made about their age so it ended up with this. I wasn't able to get mokou and kaguya to look any younger though, but I suppose the slimmer you look compared to your normal self the younger it makes you.
