Hikari Kuroda  

, 黒田 光

Hikari Kuroda is a year one student in class three who stands out due to her distinctive squid rings hairstyle. Initially, she assumes that Makoto and Sekai are romantically involved, and has a tendency to judge him negatively based on this assumption. As time goes by, Hikari develops a closer relationship with Makoto herself. Despite being quite sociable, Hikari is the most immature member of the group, often whining and meddling in others' personal lives. Her family owns a renowned confectionery store and café, particularly famous for its lemon custard pie. Hikari is good friends with Sekai and harbors unrequited feelings for Taisuke Sawanaga.
