One night, Kazuki Muto jumps in to try to save what he thinks is a girl in distress from a monster and instead gets impaled through the heart. The girl, Tokiko, is actually an alchemic warrior. She implants the only other successful work of alchemy, to take the place of Kazuki's heart. The Kakugane resonates with his fighting spirit and forms a Busou Renkin so he can fight the Homunculus monsters who prey on humans. Kazuki joins with Tokiko to battle with the Homunculi!
