Cat God: Ohanami Ghostbusters

Overview

Yuzu suggests to partake in flower viewing, so Gonta, who still has a crush on Yuzu, vows to find the most superb spot for watching cherry blossoms - however, how is he to find an empty place on such a nice Sunday? Hasumi remembers a blooming cherry tree in the yard of an abandoned hospital... if only that tree was not possessed by mischievous ghost girl.
