Has a zigzag pattern on the top of her hair. She was clinically brain-dead at age 6 and kept alive by life support until she was revived by the revival fluid. She became a member of the Kingdom of Science. Initially, her mind remained that of a 6-year-old, but she grew rapidly after helping with the Kingdom's work, making friends with Suika and Namari.

Birthday: September 9th. Age: 9 (at debut). Height: 119cm. Weight: 21kg. Blood type: O. Favorite food: Cotton candy. A young girl who always wears a watermelon rind on her head. First person: Suika. Speaks in a childish manner, often ending sentences with "...dayo" or "...nandayo." Under the rind, she is a very adorable girl, but because of her nearsightedness, she squints her eyes and makes a strange face, which she hates showing, so she hides it with the watermelon. Due to her poor vision and the rind, she wasn't very helpful with village chores, which made her desire to be useful stronger than anyone else's. Usually works with the children's team on simple tasks. She supports Senku and the others in various ways, such as acting as a decoy or taming boars. Senku made lenses for her during the production of sulfa drugs, overcoming her nearsightedness. Even after getting the lenses, she continues to wear the watermelon rind because she feels it suits her best.

Blonde hair with bangs long enough to cover his left eye, while his right eye is visible. The village's best artist. Appears whenever a drawing is needed. He is expressive, but he seems to be the quiet type as he has no speaking lines. He has a charming face with a slight snaggletooth.
