Broadcasting club member Shihono Kobayashi always gushes to her friend Aoto Endou about MagiKoi, an otome game where protagonist Fiene attends the Royal Academy of Magic. But despite the colorful cast, the one character Kobayashi is most obsessed with is the villainess Lieselotte Riefenstahl. Contrary to her rude remarks toward Fiene, Lieselotte longs to be her friend. Lieselotte is also deeply in love with her own fiancé, Prince Siegwald Fitzenhagen—the game's main love interest. Unfortunately, in almost every route, Lieselotte is doomed to a tragic end. Kobayashi manages to convince Endou to play MagiKoi to practice his speaking skills. What begins as a normal playthrough turns extraordinary when Siegwald suddenly hears the players' voices inside the game! Now labeled as "gods," Endou and Kobayashi use their comments and analyses to save their beloved tsundere villainess from her fated demise.

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. 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.
