Sumire 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 when entering Yuigaoka High, Sumire would enthusiastically take on the idea of becoming a school idol. She also has an online presence, amassing fans through her streaming broadcasts. Sumire lives at a shrine and often helps out as a maiden.
Being in the entertainment world for so long, Sumire believes her experience and knowledge of its workings is second to none. Although far from being a prima donna, Sumire nevertheless 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.
The shrine that Sumire is seen attending her duties resembles that of the real-life Onden Shrine in Shibuya. As established in Love Love! Days Vol. 13, the Onden Shrine is situated close to Yuigaoka High School.
