A female student, Kanon, visits the home of her shut-in classmate, Masahito. But when I press the intercom, no one answers. When she put the print in the mailbox and was about to leave, a man named Kita appeared. Kita says he is not from Masahito's family, but he calls Masahito a "bad kid". Kanon, feeling her anger at those words, ignores Kita's restraint and enters Masahito's room. As soon as Masahito, who was standing, saw Kanon's appearance, he laid down and devoured her body. And the fellows who were in her room also joined the act.
