An immortal companion of Yuta. She was raised by a group of old women that kept her captive and incapacitated in a hut. They were really mermaids that sought to eat Mana once she reached her adolescence to regain their youth. She travels with Yuta since, and possesses a large sense of loyalty and feelings towards him, but due to her somewhat naive and spoiled nature, she doesn't seem to truly realize that her emotions towards him are possibly love or just simple affection.

Asuta is Hazumu's best male buddy before and after the UFO crash, though his opinion of Hazumu changes somewhat due to his taking interest in Hazumu's new female form and feminine personality. Asuta is a good deal more manly than Hazumu ever was, and was trying to find Hazumu to give him some adult magazines (which Hazumu hates) on the night of the Mt. Kashima incident as an attempt to try to console him for getting turned down by Yasuna. Asuta has found himself more and more attracted to Hazumu after the transformation, leaving Hazumu completely oblivious of this fact. Eventually, Asuta resolves to simply being Hazumu's best male friend and sees that her main interest is indeed with Yasuna.
