This is a list of characters in the manga and anime series Buso Renkin.
The manga was written and drawn by Nobuhiro Watsuki, the creator of Rurouni Kenshin, with some story collaboration by Kaoru Kurosaki. It was serialized by Shueisha in the shōnen (aimed at teenage boys) manga magazine Weekly Shōnen Jump between 2003 issue 30 and 2005 issue 21/22. The story was completed in two extra chapters called "Buso Renkin Period" and "Buso Renkin After," which were published in the two issues of Jump the Revolution! in 2005 and 2006. The serial chapters were collected in ten bound volumes. The manga is licensed in North America by Viz Media, in France by Glénat, and in Germany by Tokyopop. The series was adapted as an anime television series by Xebec, which was initially broadcast in 26 episodes by TV Tokyo between 5 October 2006 and 29 March 2007. The series was also adapted as two drama CDs and a novel.
The series is about teenaged boy Kazuki Muto who is accidentally killed during a battle between alchemy warriors at his high school, and after being revived by alchemy becomes one of them. These warriors use numbered alchemial devices called Kakugane that, when activated, take on a unique Buso Renkin (武装錬金, Busō Renkin, lit. "Armament Alchemy") form based on the Kakugane's user. According to Watsuki's author notes in the manga, he based the designs of several characters on those of characters from Rurouni Kenshin.
