Hikari Kongou

Hikari is a top student in the gifted youth program. She is Kanau's younger sister. once she met Taihei she thought of him as "Onii-chan". Hikari has long white hair. She appears to have white eyelashes. She apparently has brown eyes. She usually wears her school's uniform of white with red and sleeves, due to her small physique, the sleeves extend further than her arms but nevertheless leaves them as they are. She wears diamond barrettes in her hair. When visiting the Doma residence, it's shown that she doesn't get along with Umaru as both fight for Taihei's attention, as a result Umaru and Hikari are not in good terms with each other. She appears to be shy and freezes sometimes. She loves bread. She finds Umaru's laziness very annoying. Hikari lives alongside her sister in a large apartment, during her childhood, Taihei would occasionally visit them and taught Hikari whilst there, over time, she grew fond of him and would frequently think about him even when he no longer visited her.
