Age: 38 Birthday: June 13 Zodiac: Gemini Height: 179 cm Weight: 67 kg Hasegawa used to be an official working for the Bakufu, but after an unfortunate incident with Amanto dignitary Prince Hata, whom he was assigned to serve and protect, his superior asked him to succumb to his shame and commit seppuku, hearing that he ran away from his quarters. He initially believed that humans should focus on appeasing the Amanto, but after his encounter with Gintoki, his mindset changed, which led to him punching Hata out, thus getting fired. Since then, he has been living a life of somewhat like a loser, getting fired almost every time he gets a new job, mostly due to the unfavourable look his sunglasses and goatee give him. No matter what, he refuses to remove his sunglasses because it's the only thing he had left to remind him of his successful past. Although he does exchange the sunglasses for a decent pair of half-moon spectacles at one point, he goes back to wearing them after he decides that he is going to live out his life in the best way he can. He is constantly seen working various part-time jobs. He is often referred to as "Madao", short for "marude damena ossan", which roughly translates into "totally useless middle-aged man". He and Gintoki are on good terms with one another and seem to spend most of their free time gambling. He often plays pachinko, but rarely ever wins. After losing his job for the Bakufu, he is seen doing odd jobs from time to time, like running a supermarket for a friend or driving a taxi at one time. He's currently estranged from his wife Hatsu, because of his jobless lifestyle, however they still keep in touch. It is revealed in episode 52 that he is 38 years old after he pees his pants.
Age: 20s Birthday: August 10 Zodiac: Leo Hair: Black (purple highlights) Eyes: Light Olive Green (bandage over left eye) Height: 170cm Weight: 60kg Occupation: Leader of the Kiheitai Hobbies: Smoking a pipe, Playing a shamisen A former comrade of Gintoki and Katsura and a major antagonist. He now leads a radical Joui faction called the Kiheitai and is known amongst the Shinsengumi as 'the most dangerous man in both the Joui faction and amongst the radicals'. He is easily recognizable through his bandaged left eye, his colorful kimono, his eerie smile, and the pipe he is often seen smoking. He, Gintoki, and Katsura studied in the same temple elementary school when they were children, and he fought with them against the Amanto invasion during the latter part of the Joui war. After the war ended, he vanished, and has since gained a dangerous reputation due to his assassination of many of the Bakufu's main officers and his planning of a large-scale coup d'etat. Before his first appearance in both the anime and the manga, he was mentioned to have fled Edo and to have been hiding in Kyoto, although it is unclear how long before this was. He now believes that the only way to save it is to destroy the "rotten" post-Joui war world. He is shown to like festivals, although this is mainly due to the opportunity they provide for a large-scale terrorist attack: he appears to have an attraction to ruin that is almost nihilistic. He also appears to have considerable insight due to his 'seeing through Itou's heart' and subsequently planting him in the Shinsengumi's ranks. It can be assumed that he is as skilled a swordsman as both Gintoki and Katsura, having fought alongside them as one of the 'heroes' of the Joui war. That aside, he appears to have at least considerable skill in playing the shamisen, and is shown at one point playing it with Bansai as they talk. He is based on the historical Takasugi Shinsaku.
Age: 32 Birthday: February 6 Height: 169 cm Weight: 58 kg Yamazaki is a spy, whose specialty is naturally gathering intelligence. Yamazaki is often caught by Hijikata playing badminton by himself, and he is subsequently beaten. He is often seen cosplaying as a badminton-playing version of Echizen Ryoma from The Prince of Tennis. In episode 62 he was caught saying "Mada mada dane", which is Ryoma Echizen's catchphrase. His role as a ninja is roughly based on Yamazaki Susumu, but is never really exercised besides one unsuccessful attempt to spy on Gintoki. Despite having a rivalry with Shinpachi, they most often see eye-to-eye out of their respective groups. Despite his lack of screen time, he came in 9th in the Gintama character popularity poll. But even with his popularity, Sorachi has clearly stated that he will never be on a cover of a Gintama volume. His name is based on the historical Yamazaki Susumu.
