The eldest son. A free-spirited gambling addict. Basically an optimist who doesn't sweat the small stuff, but is correspondingly slovenly and tends to handle everything half-heartedly. He occasionally shows a big-brother side, but is fundamentally the most irresponsible of the six.

The second son. A self-proclaimed cool guy who is affected and narcissistic. He often strikes poses and acts tough, but is usually ignored by his brothers, making him the butt of the joke. He is actually kind and cares for his siblings, but his efforts often backfire.

The third son. The relatively sensible one and the straight man of the group. He thinks logically but has high pride; he tries to hide his otaku hobbies (especially his love for idols), but it's painfully obvious. He often acts serious but gets carried away easily.

The fourth son. Negative, sharp-tongued, and cynical. He usually speaks in a mumble and is bad at social interaction, but he actually cares for his brothers deep down. He loves cats and only opens his heart when he's with them. He has moments of sweetness, but his cold exterior is very strong.

The fifth son. Extremely high-tension and unpredictable. Bright and full of energy, he has abnormal athletic ability and often engages in surreal behavior. He seems like a free spirit who can't read the room, but he is actually capable of sensing others' feelings. He loves baseball.

The youngest son. Good at acting pampered, shrewd, and calculatedly cute. He uses his charm to navigate the world but is often cold and dry toward his older brothers. He is proud, understands that he is cute, and has a calculating side.
