Haruka Kanari

Kanata's younger sister. She doesn't look like her brother, but they seem to share the way of getting angry.
She neither loves nor hates her brother too much. But like the childhood friend, she doesn't really want to meet him at school.
Her brother is her brother, and she accepts him, but she wants him to calm down a little more. As for her mother, Kanari has long since given up on her.
She is good friends with Chii, and is somehow unilaterally treated as a good friend by Tokoyo.
