Will this Queen with mind-control powers incite good or evil?

Fumi Nishioka lives with Kyutaro Horikita and his family of "Sweepers," people who specialize in cleaning the minds of those overcome by negative energy and harmful spirits. Fumi has always displayed mysterious abilities, but will those powers be used for evil when she begins to truly awaken as a Queen?

Fumi watches in horror as her father Yanagi turns her friends into bugs—and they, in turn, devour her beloved Kyutaro right before her eyes. In this heart-wrenching finale, does evil take all? Or will Fumi find a way to fight back even while enduring inconceivable despair?
