Nico is a fierce seven-year-old protector with messy, dark brown hair who carries himself with a rigid, hyper-vigilant posture far too mature for his age. Driven by a traumatic past, he acts as a literal guard dog for his so-called brothers, using a quick-tempered, violent exterior and an unwavering willingness to fight as a shield to keep the dangerous outside world at bay. Beneath this aggressive defense mechanism, however, Nico is just a deeply terrified, wary little boy who is intensely touch-starved and secretly craves the very love, safety, and affection he is too afraid to ask for.

Leo is a quiet and observant six-year-old whose traumatic past and abusive experiences have left him deeply wary of the world around him. Despite his young age, he possesses a striking, quiet wisdom that guides the group, making him the calm anchor among his brothers. While he is profoundly touch-starved and longs for affection, his deep-seated distrust means he approaches people with extreme caution, carefully balancing his need for warmth with his instinct to stay safe.

Kitt is the adorable four-year-old youngest of the group, instantly recognizable by his messy blonde hair and naturally endearing charm. Having bounced through foster home after foster home alongside his older brothers, he remains the innocent, sweet heart of the trio, fiercely shielded from the harsh world by Leo and Nico. Unlike his brothers, Kitt openly loves attention and eagerly seeks out physical touch, bringing a pure, childlike light to their small, protective family.
