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?

After sacrificing himself fully to his snake, Kyutaro narrowly avoids vanishing altogether. Now he’s taken on all the powers of his snake and knows the true location of the Casket! But will the Genbu Sweepers venture to open that door when Fumi’s life could be at stake?
