|Love Interest||Numano Himemiko (lover)|
Kotarou Urashima (小太郎・裏嶋), one of the main supporting characters first shown in a flashback when Himemiko requested Nanami to help her to find a way to meet him again. Kotarou was shy around Himemiko when he first met her but, after getting to know her, grew fond of her and eventually fell in love with her.
After discovering Himemiko was a yokai, Kotarou rejected her for lying to him about her true identity. After clearing his thoughts and some persuasion from the Dragon King, he interrupted Himemiko's marriage to Nishiki, and Himemiko's true form emerges while they are escaping. Kotarou shows an amused expression (and almost lost his breath, as they were underwater) before telling Himemiko that he accepts her no matter what her appearance was. Afterward, they have a steady growing relationship after this and plan to go to Disneyland together.
Kotarou is technically a shy type of boy who doesn't blend well with other people, claiming his only good point was probably his skill in solving rubix cubes. He has low self-esteem, making him doubt that Himemiko actually loves him and that it might just be a cruel prank of some kind. However, after undergoing some obstacles in their love, he realizes Himemiko's love for him is true, and so is his love for her.
Himemiko is his lover, because of her, he tries to be stronger and move forward. He felt betrayed when he learned of Himemiko's secret of being yokai but the Dragon King advises that Himemiko was probably just afraid of hurting him and if he wanted to be trusted, he must become reliable and strong. He aims towards that attitude ever so slowly and after apologizing to Himemiko, their love gets stronger by the day.
He had meet Nanami and Tomoe when they were trying to found him so that him and Himemiko could meet again. His grateful towards Nanami for getting him and Himemiko together.
