She only remembers things up till spring of her 6th grade year, hence: she has the mentality of a grade school kidâ€¦ and forgets about her boyfriend, Kakurazaka Hikaru, a well-known exorcist as well. Mugiko and Kakurazaka will work together to exorcise spirits whenever they are hired, despite the little accident. Meanwhile though, Kakurazaka, known for being a perverted hothead, will try to regain Mugikoâ€™s memory backâ€¦ to be romantic with her once more!!
