Kokoro Katsura

**Height:** 122 cm (4’0”)

Kotonoha's younger sister. Unlike her shy older sister, she is very talkative, full of curiosity, and likes to tease Kotonoha around, but she actually worries about Kotonoha a lot. She often wants to play with Makoto during his visits at her house. Her first name means "heart" in Japanese.
