He wears a red short-sleeved shirt, long black pants, a white apron, and black wrist gloves. He is terrifying when angry—enough to make even the loudest person freeze in fear. When he's enraged, a red glow appears in his eyes. He is extremely overprotective and acts like a tsundere. He is Roberry's older brother. Age: 16 On the surface, he pretends to dislike Cosmo, but deep down, he secretly likes and worries about them. Despite his act, his face turns red whenever he is around Cosmo.

Female Height: 157cm She wears an ivory shirt with a short, dark red overall skirt. She has a light green ribbon on her back and a pink striped ribbon around her neck. She has white hair with small strawberries and leaves on both sides of the top of her head. At the back, her hair is tied into two slightly larger strawberry-shaped bunches. Like typical siblings, she fights with Sprout a lot, though they occasionally get along. She likes Cosmo (as a close older sister figure). She is very talkative, loud, and never quiet. She pulls aside any girls who cling to Sprout—except for Cosmo—and tells them to back off. Age: 14 She is Sprout's younger sister.
