草萼水称

Kanon's younger brother. He loves him a bit too much. He's rude and harsh towards anyone that isn't his brother, and he's quick to get in a bad mood. He's especially hard against people who are close to Kanon. He might be a yandere. He can transform his arms into sharp wooden branches. Apparently he had a fight with Kanon in the past.
