Hashima Ichika

The anime-loving, chuuni little sister.

Reiji's precocious little sister. Determined to appear like a regular girl at school, she keeps her love for anime a secret from her friends. Ichika's a good kid at heart, despite her childish fascination with anything sexual.

Having always wanted a big sister to play with, she immediately warms to Arisu. They both love dressing up as magical girl characters, often cosplaying together. Ichika uses every excuse in the book to jump in the bath with Arisu, too.

Her family calls her "Icchan."
