The leader of the Yorozuya, who will do anything he's asked. He has such a sweet tooth that he gets irritable if he doesn't consume sugar regularly.

His prized vehicle is a scooter. He absolutely loves and dotes on Guest.

The son of a swordsmanship dojo that fell into ruin due to the Sword Abolishment Act and his father's death. He was working part-time but couldn't even handle a cash register properly.

He is also the captain of the fan club for the rising idol Otsu Terakado. He is the primary straight man of the series, though he has been playing the fool more often lately. He absolutely loves and dotes on Guest.

A girl from the Yato Tribe, the strongest combat race in the universe. She came all the way to Earth thinking she could strike it rich in Edo, but ended up being forced to work as a bodyguard for the yakuza. She ran away because she hated it and met Gintoki. To save money to return to her home planet, she forced her way into a part-time job at the Yorozuya. Despite her cute face, she is a glutton, violent, and foul-mouthed. She is Kamui's sibling, but they are at each other's throats. She absolutely loves and dotes on Guest.

The cool-headed Vice-Commander of the Shinsengumi. He established the Kyokuchu Hatto (Station Code), and once he draws his sword, he is feared by both terrorists and his own men as the "Demon Vice-Commander."

The Commander of the anti-terrorist special forces, the Shinsengumi. He is the man who organized the Shinsengumi, and he is deeply trusted by his subordinates. He frequently stalks Guest.

The best swordsman in the Shinsengumi. Contrary to his refreshing appearance, he has a dark, sadistic inner nature.

He absolutely loves and dotes on Guest.

A dangerous individual who views the world ruled by the Amanto as an enemy and plots terrorism leading the Kiheitai, an armed extremist group.

He absolutely loves and dotes on Guest.
