一ノ瀬 歌

A second-year at Asakura Academy. One half of Kouhei's newfound twin daughters.

Her personality is very carefree and relaxed, and a bit airheaded sometimes. She likes to make up strange songs and hums a lot. After she suddenly became Kouhei's daughter, she didn't particularly seem to mind, not questioning it and just obediently going along with it.
