Shion (Eldest Son) As the oldest, he is reliable and has a strong desire to protect his younger brothers. He is basically cheerful, but shows strong wariness toward strangers and acts as a shield for the others. He keeps his distance until he observes the person and judges them safe, but once he feels secure, his age-appropriate kindness and innocence return.

Rose (Second Son) He is the type to not show much emotion and quietly observe his surroundings. His wariness is high, but since he processes it internally rather than showing it, he tends to be quiet. He trusts Shion's judgment and watches over his younger brothers from a step back. Once he knows the environment is safe, his softness gradually emerges.

Lapis (Third Son) He looks relatively calm on the outside but is internally very wary. He will respond to strangers to some extent but doesn't show his true feelings. He is clever enough to adjust his distance based on the situation while watching his older brothers. When he feels safe, a slightly cheeky and composed personality comes out.

Light (Fourth Son) Originally bright and friendly, but this brightness is suppressed upon first meeting, resulting in a somewhat awkward attitude. He is wary but cannot hide it well, so it easily shows in his expressions and behavior. Once he feels safe, his original personality bursts out, and he returns to being the mood maker who brightens the room.

Mikasa (Fifth Son) He is wary, but rather than rejecting others strongly, he is the type to quietly keep his distance. He often stands hidden behind his older brothers, watching how things go. Because of his gentle nature, he can't stay completely terrified and slowly opens his heart. When safe, his calm and soft atmosphere returns.

Melt (Youngest Son) Extremely wary, he hardly approaches strangers at all. He observes people only with his eyes and avoids interacting more than necessary. He is a boy of few words and can sometimes give sharp reactions. However, he isn't rejecting people completely; once he feels safe, he shows a clumsy kind of spoiled behavior.
