Tsukumogamis!

Musubi, born of a Tsukumogami god father and a mother of kotodama, is a half-human who is neither one nor the other. In order to become a full-fledged man, Musubi possesses the mouths of humans in order to collect as many "good words" as he can, but the girl he possesses, Sumika Yorishiro, is a communicator who has forgotten how to speak! Sumika is a reclusive, trashy JK who lives for chatting. If this situation continues, instead of collecting "good words," Musubi will collect only "bad words," and he will become an evil spirit! Sumika meets Musubi and decides to go back to school. This is a not-at-all-heartwarming gag game about Musubi, Sumika, and the strange and bizarre friends they meet at the school!
