Sakata Gintoki Shrine~ - MyAnimeList.net

Information

Sakata Gintoki is a samurai living in an era when samurai are no longer needed. To add to his troubles, oppressive aliens have moved in to invade. Gintoki lives with Kagura and Shinpachi, taking on odd jobs to make the world a better place...and to pay their rent. In the Joi war, he was known as the "White Devil" (Shiroyasha) due to his silver hair and white coat he wore in battle, which, combined with his impressive capabilities as a swordsman, made him famous among his comrades and struck fear into Amanto.
Gin has two major obsessions in life. His first is a sweet tooth that has him obsess with sugary, sweet foods such as parfait, ice cream, and cake. However, this is a problem in itself in that Gintoki has to control his sugar intake as the doctor has warned that he is on the verge of developing diabetes. His second obsession is reading the magazine Weekly Shōnen Jump. Gintoki will go to great lengths to get the latest Jump issue, to the point of reckless behavior leading to situations including an incident of memory-loss and a showdown with fellow Jump obsessee (and skilled ninja) Hattori Zenzo. His Jump obsession makes him easily dream of being like other Jump heroes, including wishing that he had a "Bankai" similar to the hero characters of Bleach.
