"so i've been trying to find ways to make Saiko's mouth work for MMD using an already ported model, but i never knew inside her head were two hearts that never ever show up in-game, not in cut-scenes or when you play, is there any reason why they are here? i suppose that they would've appeared when Saiko sees you do something she likes, but that's just a guess, sorry if this spoils anything for future updates, just a curious find.

Saiko belongs to habupain and all those involved with the making of SNS"
