Mana Ishizuki

Mana is Yorito's friend from school; she often gets annoyed at Yorito for how he spends so much time taking photographs of the sky instead of spending more time with his sister.

Mana works as a waitress at the Azure Restaurant and often comes over to Yorito's house to cook for him. She looks after her younger sister Koyori. She also knows about Matsuri's secret.
