When good-for-nothing employee Daichi, who has a crush on his senior associate Nozomi, is attending to a backlog of work with colleagues, a frightening game of tag targeting people with type-B blood begins. He saves Nozomi from peril, but falls for her boyfriend Sakuya's plans and gets kicked out of the company.
