I've seen the Jinki anime but I have no idea who the girl between Shiba and Satsuki is. It's been awhile since I saw it though.

Also: void_inside, please use *some* tags. Even just swimsuit. There was nothing when you upped it.

From what I can see, that is Tsuzaki Shizuka when she was younger. Haven't seen that one yet, but even on here there are other examples of her younger self.

Thankfully that means no new tags needed, unless I'm mistaken.
