Eiji Shinozuka

Morino's secretary.

A half-demon who, like Kotoha, once "fell" and was brought back by Maki Haru's hand. As a result, possesses abilities beyond those of a human. Originally lived in Sakurashin Town, but regretted falling and found it difficult to stay in town, so moved to the neighboring town at Morino's invitation. Therefore, follows Morino faithfully and does not disobey his orders. During the incident, opposed until the end while listening to Morino, instructing others to take the blame alone. After the incident, remains in the neighboring town and works to cooperate with Sakurashin Town. Appears stern at first glance, but has a playful side, such as mistaking the designated meeting place, and a lonely side, like asking Akina and others for tea or shopping invitations. Referred to as "Zuka-chan" by Kotoha.

In the first TV anime series, the role is significantly different, appearing as a half-demon serving Enjin. Also has the original anime ability of high-speed movement.
