Manatsu is a rich kid with an obsessive crush on the Kaiju—like, she's really into it. She goes to school with Kuroe, and the two end up becoming best friends, though Manatsu has no idea that the Kaiju she's so hung up on is actually Kuroe in disguise.
She's got this whole thing where she dresses up as a butterfly whenever the Kaiju appears, hoping it'll stomp her flat. Yeah, it's as weird as it sounds, and fans often note it's probably her strangest trait.
