Six sons, six different personalities
All part of one family,
each living along his own path.
Eldest son Yuya Takaki: A company employee who, unexpectedly, has all sorts of different identities. He spends a lot of time away on business trips, but his younger brothers are very fond of him. He especially dotes on the third son.
Second son Keito Okamoto: An English teacher, quiet, honest, gentle, and steady. He's a good older brother to his younger siblings, and the younger brother his eldest brother can count on. Because of his marriage, he and the family are locked in a cold war.
Third son Yuri Chinen: Lead singer of a band, though it's only an underground band. The little tyrant of the family, and a mischievous rascal.
Fourth son Yuugo Kochi: A delinquent high schooler with a brother complex. He adores the youngest in the family.
Fifth son Juri Tanaka: A child who went missing by accident when he was young. He's in the same class as the fourth son, and learns his true identity through a twist of fate.
Youngest son So Matsushima: A middle schooler who idolizes his third brother, but becomes a different person when he's out of his brother's sight. He likes roughhousing with his fourth brother, but knows how much his brother spoils him. He's good at cooking.
Second son's wife Yuto Nakajima: An obstetrics nurse with an unusual constitution. Though he is a man, he can give birth, and for this reason, his marriage to Okamoto is not accepted.
Third son's husband Ryosuke Yamada: The band's bassist, though he's actually good at playing the saxophone. He has a natural flair for acting and is utterly devoted.
Fifth son's wife Taiga Kyomoto: His father is a famous actor, and he's classmates with the fourth and fifth sons.
Youngest son's husband Shori Sato: The youngest's upperclassman, outstanding in both academics and character.
