After-school H Experience of the Zlumke Triumvirate : Yui Hatano

After school, the female teacher Hatano and the executive committee members were preparing for the cultural festival. When the time is too late to return, it suddenly becomes a power outage. Although Hakatano tries to find out the cause, all doors are locked and can not go outside. Under such circumstances, the boys began to plan to attack and gradually get excited about the situation in which they were trapped with Hatano.
