Kijima Hyouka

She is the younger twin sister of Mizusaki.

Her emotions are not very volatile, and her facial expressions rarely change drastically. She rarely voices her opinions, and people often say, "I don't know what she's thinking."

She was adopted by the Kijima family at a young age, and grew up separately from Mizusaki.

Her biological father is a painter, and perhaps influenced by him, she began to paint.
She is a member of the art club at school, and is often found staying up late to paint in silence.
