Yuka Moriyama, alias Bunny Laker, fled her destroyed homeworld of Blade Star to settle on Earth. Possessing a Super-Lake Crystal, she transforms into a superheroine alongside her teammates. As the youngest Laker, Yuka stands 156 cm tall, distinguished by her long pink twin tails and matching pink eyes, with measurements of 78 cm (bust), 57 cm (waist), and 83 cm (hips). On Earth, she lives as a school student and manages the soccer club where Akira Daidoji plays. Yuka harbors intense romantic feelings for Akira, visibly apparent to those around her. This openness sometimes attracts unwanted attention from other club members. Unlike her fellow Lakers, Yuka lacks specialized combat abilities or unique fighting techniques. Her role within the team centers around support and interpersonal bonds, particularly her persistent affection for Akira.
