Koko Matsumoto

Koko Matsumoto is a secondary character in WATATEN!: An Angel Flew Down to Me and one of Miyako Hoshino's neighbors.

Biography
Koko was formerly in a club with Miyako back in high school, but the one issue being that Miyako hardly remembered her. Despite this, Koko had become obsessed with the young woman to the point that she mimicked the types of clothing that Miyako would make right down to the exact fabrics that were used to make them. She had also had the habit of taking her younger sister Yuu on walks close to Miyako's house, all but stating that she stalks her.

Koko shortly finds kinship with Hinata over their shared love for Miyako, becoming fire-forged friends as a result. Even though she was initially unsettled by her earlier because of her behavior, Miyako also comes to view Koko as a friend even trading contact information with her as well as giving her some of the baked goods that she would make for Hana and the others. In return, Koko would provide backup. In one episode when the main trio's mothers arrive to the Hoshino house to speak with Miyako, Koko speaks up in her defense when Miyako was initially worried that they would take her as some creep for coercing their daughters into wearing different cosplay outfits and taking pictures of them. In the final episode, Koko stages an orderly line when the students arrive after the end of the school play.
