Medabots—powerful robots granted artificial intelligence through special "medals"—serve at the whims of their owner. They are more commonly used in "Robbatling," a popular combat sport where two medabots face off against one another. In its professional form, Medafighters use their Medabots to qualify for the World Tournament and fight amongst the elite to gain the title of champion.

Fortunately, however, Ikki manages to find a medal in the nearby river; but when Ikki places it into Metabee's head, the latter starts to exhibit strange behaviour. Short-tempered and rebellious, he refuses to obey Ikki's orders.

On a sunny afternoon in her Paris apartment, assassin-for-hire Mireille Bouquet receives a strange email from Kirika Yuumura, a young student from Japan, inviting her to "make a pilgrimage to the past" together. Initially thinking the email is nonsense, she changes her mind when it begins playing a song that she recognizes from her youth. Upon first meeting each other in person, the two are suddenly ambushed by gun-wielding men. While Mireille is capable of fending off the assault, she discovers that Kirika is quite adept in combat situations after she takes out several gunmen on her own. Despite her proficiency at killing, Kirika laments her inability to feel remorse for her victims. In addition, Kirika apparently has no memory of how she came to acquire the skills she possesses or even of her real identity. Sensing shared history between them, Mireille agrees to team up with Kirika, and together, they embark on a journey to uncover the mysteries of their pasts. Operating under the codename "Noir," the duo's fragile alliance is tested as they begin accepting jobs, each one bringing them closer to the truth of who they really are.
