**Background:** Sumire who lives with her parents and a little sister has always lived the life of a performer. Having been thrust into show business as a child, she intensely devoted her formative years to the craft of pleasing an audience. She avoided extracurricular activities in an attempt to balance such a life, but after entering Yuigaoka High, Sumire would enthusiastically take on the idea of becoming a school idol. Sumire lives at a shrine and often helps out as a maiden. She enjoys studying Japanese and Japanese history. <hr> **Personality**: Being in the entertainment world for so long, Sumire believes her experience and knowledge of its workings is second to none. Somewhat of a prima donna, Sumire assumes that most people already know her name. Somehow attached to the idea of her own stardom, Sumire dreams of becoming a famous school idol not just in Japan, but "across the galaxy." But Sumire also takes her more earthbound duty as a shrine maiden very seriously, warning those like Kanon to not aimlessly ask the gods to do everything for them, such as helping them become school idols. Instead, Sumire believes that they should do their best together without help from the gods and make their own wishes come true. Sumire was shown to be a confident character who was very self-assured. However, this was most likely a mask. Through a few episodes, we see Sumire always being chosen as second place. Her goal is to become world famous or something similar. However, she feels like she is always the second option and that is clearly shown in episode 10. She feels like she's the worst, so she always acts like she's the best. At the end of episode 10, we finally see Sumire embracing her emotions. Her favorite saying is, "Faith will move mountains," and her catchphrase is "Galaxy~!!!". <hr> **Appearance:** Sumire has a slim and tall figure with long legs, long hime cut blond hair, melon green eyes, and wears a red headband. She possesses the feminine beauty ideals of an all-round natural beauty.
