Touko Ichimiya

Оригінальне ім’я: 一宮塔子

Taishi's tsundere younger sister, noted for having a peculiar marking under her right eye similar to the "bulging vein" image used to depict a person when angry. Staying true to this quirky trait, Tōhko is often in a bad mood and has a short temper. On the other hand, she seems to have a brother complex. Ever since learning about her older brother's interest in working as a public servant, Tōhko started learning more about the job, and by high school is knowledgeable enough to give surprise quizzes to employees every time she visits her brother's workplace. Her birthday is on Christmas Eve.
