Munto

Ruler of the Magical Kingdom (one of several kingdoms in the sky). He deliberately falls to the dangerous Underworld in a desperate bid to contact Yumemi and save his people and the heavenly world. He is proud and stubborn to a fault, but also strong and courageous. In the 2nd OAV, like Yumemi who sees his past he sees hers in exchange, though both unwillingly and subconsciously. He grows closer to her in that sense and is even more hesitate to reach out for her help, afraid that if he did she would disappear in an instant, a theory that terrifies him so. It is Munto this time, who is hesitate and is unwilling. Munto truly does care deeply for Yumemi.
