Kohaku Kawashima

Kohaku Kawashima is a character of Sound! Euphonium series. She is the younger sister of Sapphire Kawashima. Like Sapphire Kawashima, Kohaku has messy and wavy chin-length gold-ish hair that has a piece of her hair pointing up with a blue polka dot ribbon on the right side, green-ish lime eyes, quite thick eyebrows, a cute and round-looking face and rosy cheeks.

Kohaku is a shy and timid girl who also tends to be childish and expressionless sometimes, but she is friendly and soft-spoken who has good manners, just like Sapphire Kawashima.
