I'm also pretty sick and tired of the short hair, outspoken, quiet girls getting female leads and the most air time. Hopefully Koko and the main character establishing a relationship in episode 1 will be a sign of ruin later on in the episodes. Maybe I've been reading too many incest h-manga's in /h/, but please don't let it end with Koko.
Well as the plot summary suggest, Yoshiyuki and the Asakura sisters are cousins to a certain extent. Yoshi is the make-believe child between Sakura and Juiinchi.

I'm a little annoyed that the magic tree continues to be the center plot device. Sakura above everyone else knows how much misery the tree can bring.
