Seike Yuu

"It's natural to worry. You're my family."

The heir of the Oto Jingu Shrine. He is bad-mouthed, but also serious and sincere. Due to his mother running away under the influence of a young man, he is not good with women.

He has special feelings for Kuro, who has been living with him since childhood. However, for some reason, everyone around him incorrectly thinks that he likes Mashiro, so he's troubled.



One of Kuro's love interests.
