Psycho Mari

"Mari is a lonely girl. So lonely in fact that she is the only person in her household, one she never dares to leave. The only companion is the corpse of a little Teuthida who one day suddenly comes out of her toilet.

Unknown why he is there and how he got in the toilet, considering he is an Aquaphobic, Mari is forced to bring him back home as her new friend, Igor, wants to return. For the first time in her life, she must go to the outworld on a journey to help her new sidekick/friend."
