Azusa Fujisaki

is a first-year student at Saint Ishiyama Academy. She is Kazuya Yamamura's friend and classmate and an easy-going, light-hearted girl who quickly gets on good terms with Kunieda and Oga, even rooting for them in their fight against the Six Knights.

Kazuya Yamamura
Kazuya is the childhood friend of Azusa. Both have a very close relationship of a sibling-like nature, but it is sometimes seen that Azusa has some sort of affection towards Kazuya, yet Kazuya is not completely shown to reciprocate those feelings as well.
