Hayato Ichijiku

We first see Kyuu hiding from some girls, and sneaks into a festival shop where Ageha is working alone. He brings up many crazy ideas and if she needs any boy help when he sees a picture of a boy with her in it. He doodle on it hearts and love quotes, and tells her to go after her dreams. Which, does in fact help Ageha. Later it is shown he is quite a flirt to her, and even helped Ageha down when she was in stress. It is shown that Kyuu really does matter to her, in a friendly-way. Also it is shown that he is agehas boyfriend.
