Moroha is often the target of Shizuno's perverted antics, such as when she (purposely) shoves his head into her breasts, with each occasion making Satsuki jealous and leaving him uncomfortable with the situation, and from time to time, is randomly kissed by Shizuno as well. Their meeting started off by Moroha waking up a sleeping Shizuno (ironically, both of them fell asleep) who instantly kissed him after muttering Shu Saura, a past life of Moroha, who in the past, both were husband and wife. The two first met in the school's auditorium, following Mari's speech on what their role would be in the school. Shizuno is a classmate and friend of Moroha.
