Welcome to the club.

The special product of this town is pumpkin.... Pumpkin and Halloween are used to liven up the town. Shunsuke's high school usually has a school festival at the end of October and his class plans to open a ghost house for the festival. There is an old house standing next to his apartment and it seems no one lives there. They decide to use this house as a ghost house. Shunsuke goes inside to look around and meets monsters.... He runs away but next day, a girl comes to his place with three followers. It seems that he met them before... actually, they are the ones he met at the old house! "We request for your cooperation!"

This story is about a young boy named Toono Shiki who, after experiencing a traumatic accident, wakes up in the hospital with the ability to see lines and cracks in every surface and being. These lines, when traced with any sharp or blunt edge, will be permanently cut. As he is forced to see these lines everywhere, Shiki is distraught until he meets a mage girl who gives him glasses that allow him to live a normal life. Years later, after living in a relative's home, the death of his father has him summoned back to the mansion he left years ago. There he must learn to live with his younger sister and two maid girls. One day Shiki's life takes a turn for the worse when, on the way to school, he meets a blonde woman and he's overcome with the urge to kill her.
