Ryota, a neighborhood child with droopy eyes and dark, permed hair, is often clad in a semi-dark t-shirt. His quiet, shy demeanor renders him reserved in most interactions. Though initially wary of Tatsu’s intimidating presence—dubbing him "the scariest-looking guy in the neighborhood"—Ryota gradually cultivates a friendly dynamic with him. Their bond unfolds through babysitting episodes and casual neighborhood exchanges, transitioning from hesitance to shared activities and lighthearted moments. Notably, Ryota inherits his father’s distinct hairstyle, a trait highlighted in one episode. His name, fusing the Japanese characters for "cool, refreshing" and "thick, big," aligns with cultural naming practices.
