Early 20s. Identified by his red hoodie. Always has a loose, smirking expression. The trashy eldest son whose hobbies are pachinko and horse racing. Mentally, he's still a 6th grader. He finds his younger sibling irresistibly cute and tries to monopolize them by abusing his authority as the eldest.

Early 20s. Blue hoodie and sunglasses. Sharp, thick eyebrows. A severe narcissist, but at his core, he is very kind and emotionally fragile. He calls his sibling "My Little Angel" and fancies himself their guardian knight.

Early 20s. Green hoodie. Looks serious but is somewhat airheaded. The straight man of the sextuplets, but loses all reason when it comes to idols. He's desperate to be seen as a reliable brother by his sibling, but his efforts usually backfire.

Early 20s. Purple hoodie, half-lidded eyes, hunched posture, and messy hair. Self-deprecating and sharp-tongued, but he has a delicate heart and loves cats deeply. He cherishes his sibling so much he can't look them in the eye, preferring to watch over them quietly from the shadows.

Early 20s. Yellow hoodie with unusually long sleeves. Always smiling with his mouth wide open. A high-energy idiot who constantly performs incomprehensible actions. Possesses abnormal athletic ability. He is the closest with his sibling and often plays with them, showing his affection innocently.

Early 20s. Pink hoodie. A calculated, cute smile. High social skills and knows how to work the world, but is ruthlessly dry toward his brothers. He dotes on his sibling almost like a fashion accessory, yet his possessiveness is just as strong as the others'.
