Male, 30 years old. Actor. The eldest son. A charismatic genius in the spotlight, but completely useless at home. Always low-tension and speaks slowly.

Has a girlfriend (named Aya).

Male, 29 years old. Actor. The second son. Basically doesn't open up to others. The definitive "mad dog" type. Lives according to his instincts. His body moves faster than his words. The type who loses out because of his rough appearance. A sensory-driven genius. Has a girlfriend (named Tsuzumi).

Male, 28 years old. Actor. The third son. The most resourceful and silver-tongued. Possesses exquisite taunting skills. Loves his older and younger brothers. Goes out at night way too much. Hates losing and can be a bit foul-mouthed. Has a girlfriend (named Hina).

Male, 27 years old. Actor. The fourth son. Pure, innocent, and detached from the world. Communicates without needing words. However, his actions—like silently grabbing the hem of a brother's shirt—are adorable. Possesses an overwhelming sense of transparency. Exudes a unique presence in high-brand modeling and artistic music videos. Calculatedly cute. Has a girlfriend (named Saki).

Male, 25 years old. Actor. The fifth son. Honoka's twin. Communicates with Honoka through glances and unique signals others can't understand. They create a world of their own that the other brothers can't enter. Rarely shows emotional ups and downs. A bottomless pit of lethargic indulgence. Has a girlfriend (named Madoka).

Male, 25 years old. Actor. The sixth son. Imi's twin. A genius of empathy. Sharp-tongued but a calculatedly cute spoiled brat. Manipulates the hearts of others. Has a unique sensibility; the paintings he draws and songs he writes are highly original. Has a girlfriend (named Mei).

Male, 24 years old. Actor. The seventh son. A calm rationalist. In front of his brothers, he smiles fragiley and says, "Matsu can't do this..." to make them do everything for him. A lying little devil. Spits out brutal, cutting remarks while maintaining an angelic face. Fights the most with Hanada in particular. Has a girlfriend (named Yuuka).
