Chiya Sakagami is a supporting character in the series of mini episodes and manga I've Had Enough of Being a Magical Girl. She is usually emotionless and speaks in mono-tone voice. She can see and hear Miton, and has the aptitude of a magical girl; however, the limitation in Miton’s capacity prevents her from really becoming one.
- She is Yuzuka Hanami’s friend who deems Yuzuka as “most important friend” and truly cares about her; for example, she is on guard against Miton for the good of Yuzuka.
- She is fascinated by Yuzaka’s status and figure as magical girl, like when she agreed with Mafuyu Shinoki about the cuteness of her magical swimsuit outfit with a blushy face.
- The opening of the second season shows how much she is close to Yuzuka, like when she lets her sleep on her lap, and grabbed her arm at the end of the opening, and connected hands with her pushing her cheek against hers.
- She knows that Miton is just trying to look out for Yuzuka yet she requested it to really save that for after Yuzuka considers it one of her friends.
