Ryuuichi's younger brother who's quiet and bookish—the strong, silent type. He's genuinely attached to his older brother and pretty protective of him, which is sweet considering the age gap. What's notable about him is how mature he is for a toddler. He's caring and thoughtful in ways that feel almost unusual for his age, and he often ends up playing peacekeeper when things get chaotic in the nursery. Fans often note how he balances out the more energetic kids around him.
