No.4 of the Muto-assassination team. Maruyama is a bishounen that is usually under the disguise of a fat, chubby ball, until Tokiko cut open the disguise with her valkyrie skirt. He was able to shrink Tokiko to 34CM in their first battle, then shrink her to nothing in their second battle, only to find Tokiko still has 4CM remaining, and went into his stomach. He was defeated as his guts were ripped out by Valkyrie skirt. His special ability is that he can draw a circle without using a compass. In the anime, he, Inukai, Chitose, Busujima and Shusui were sent to fight Victor, but lost against Victor&#039;s Buso renkin, Fatal Attraction, and was forced to reteat. He doesn&#039;t use his fat man disguise in the anime either.    (Source: Wikipedia)

The story begins when high school student Kazuki Muto is killed one night saving a mysterious girl from a monster, only to wake up in his school dorm, believing it to have been a dream. However, he soon finds out that dream wasn't a dream at all when a giant serpentine monster attacks him and his sister. Tokiko Tsumura, the girl he saved, explains that the monster is a homunculus. Kazuki had been attacked and killed by it when he was rescuing her. However, she, feeling responsible for him, revived him by placing a Kakugane medallion in his chest, serving as a replacement heart.<br><br>
The Kakugane, as Tokiko explains, is an alchemical device that, when activated, takes a certain form based on the Kakugane's user, forming a unique Buso Renkin. The Buso Renkin is the only thing that can destroy a homunculus monster. Using this, Kazuki creates his own Buso Renkin (the "Sunlight Heart", a huge lance). Along with Tokiko and her own Buso Renkin (the "Valkyrie Skirt", an execution scythe), Kazuki joins the fight against the homunculi and their master.
