Oto

Kumi lives a hippie-like life in Tokyo's outskirts. One night while drunk she stumbles into an abandoned industrial site, except in addition to deserted factories, it is full of forests and greenery. She decides to move there, even further away from the civilization she had already left.

In consequence of his professional mistakes and declining career, Shuji and his family, the Sasaya’s, are forced to leave the wealthy suburb of Tokyo. The move is slow, long and heartbreaking, and the two Sasaya children, an old teenager and a young adult, unwittingly turn the grieving process into an exuberant and unpredictable farewell party!

In the ruined house, a member of the rock band breaks a seal to shut Melon the witch. And then Melon murders the members of the band one after another.
