Hayaryuu

Hayaryuu is the slash ship between Kamitani Hayato and Kashima Ryuuichi from the School Babysitters fandom.

Canon
When Kashima met Hayato for the first time, he thought that he was that type of person because he punched his little brother on the head, but then Kamitani tells Kashima that he have to go to see his little brother (Kotarou) because he felt alone without him. When Kotarou got sick, Kashima inmediately ran right to Hayato and asked him if he could guide him to the nearest hospital. Kamitani didn't think it twice, and he left his little brother in care of his mother and helped Kashima giving the right direction to the hospital. The next day, Kashima thanks Kamitani for helping him and then he went to class where he noticed that Hayato was there too. While he was introducing himself, he looked nervous, but after he saw Kamitani, he got calm and then gave a little smile to him and then finished his introduction.

Anime moments
When Kashima was heading to his classroom, he felt uncomfortable because the people surrounding him were giving him a stare and he thought that it was him that he was getting many weird stares. When he asks Kamitani if he had something in his face, he asked in response what was he doing with the kids tagging along behind him. Ryuuichi panicked and apologized to the people surrounding him and then asked Kamitani if he could help him taking the kids back to the Daycare center, which Kamitani accepts.

The next day when the kids with Usaida and Kashima were going to an excursion, Kamitani passed right where they were and then he asked Kashima if he could leave his little brother in his care, which Ryuuichi accepts and then he asked Kamitani if he forgived his little brother already (because he punched him again), he said that he didn't really liked him and then his little brother hears what he said and ran to another place of the excursion with Kotarou. Before Kamitani left the place, he told his little brother not to cause problems to Kashima and everybody else, showing that Kamitani cares about Kashima first than another people. After the excursion, both guys are showed up walking together back to their homes while carrying their brothers. When Kashima asks to Kamitani that if he was worried about his little brother, he said that his mother found him in the baseball team and then smacked him telling that he needed to be with his little brother. Kashima smiles while he said ''Even so, i'm glad. He was lonely without you, and Kamitani's little brother, which it was asleep, he said that he loves Kamitani and then he blushed a little while he replied; Idiot, i don't really hate you either''. Kashima laughs and said that Kamitani can blush too, which Kamitani complains and tells Kashima that his little brother (Kotarou) likes him too much, and we can see Ryuuichi complaining about that.
