波摩

Hama is Misha's mind guardian. She lives in Misha's spiritual world, known as her "soulspace" or "Cosmosphere".

Hama will not open her heart to you at first because of some past memories. Lyner must solve the mystery to the memories and Misha's past to find out about Hama's true thoughts.

She appears as a little girl with cat ears on her head, dressed in Japanese robes, and holding an ocarina.

Hama was originally an ocarina that Lyner gave to Misha when they were children. Misha's strong feelings for the ocarina, which she named Hama, gave Hama a physical form in her soulspace./
