Warui Ko no Tame no Wasuremono Techou(2009)

Warui Ko no Tame no Wasuremono Techou

A collection of short stories. Chapter 1: Sano tends to forget some things - a wallet, a pen. Little things. There are also things he doesn't forget - like making sure Ashihara is around to remind him when he "forgets" something. It's not deliberate. Really.
