Add a short synopsis here.
Eucliwood Hellscythe decides to unleash her power as Ayumu notes that she's possibly the most powerful "masou shoujo" ever, and as a result has been attracting all the oddities that have converged on Ayumu's life. Yuu reveals that she has the power to kill someone just by having them hear her say "die." As Kyoko gained the power to add the lives of those she killed to her own, Yuu is forced to repeatedly kill her off, but at one point Kyoko breaks her own eardrums so she cannot hear her words and unleashes a gigantic blast of her own, knocking Yuu out of the fight.
The others rush in to help and Ayumu decides to transform into a masou shoujo again, taking Haruna's chainsaw and killing Kyoko again and again until she is down to her last life. But at the end, Ayumu decides to spare her. Dai-sensei suddenly shows up and thanks Ayumu for sparing Kyoko's life as she plans to leave with her. However, Kyoko stands up and speaks with a male voice before disappearing from the scene.
Back at the house, Yuu tells Ayumu that the voice came from another zombie she created before, but was then forced to destroy when he became evil.
