Birthday: November 9

Temperamental and fastidious, Hikari Kuroda is a student in year one of class three, recognizable by her signature squid rings hairstyle. She initially believes that Makoto and Sekai are dating from the very start, and tends to negatively generalize him; later growing closer to him herself.

Though she is actually quite friendly and social, Hikari is the most childish of the cast; sporting an unduly knack for whining and prying into the affairs of others. Her family owns a confectionery store and café, famous for its lemon custard pie. Hikari is good friends with Sekai and has an unreciprocated crush on Taisuke Sawanaga.
