- "If you don't have any particular plans, we thought maybe you could see if she's okay."
- — Coo —
Coo is a Wavemaster. While adventuring in a field with her friends Nei and Kira she noticed Haru being attacked by a monster. Too weak to help her herself she returned to town, where she asked BlackRose to help out. Her way of speaking and acting reminded BlackRose a lot of Mistral.
