Yes, I am the Harbinger of Death

Eucliwood negates all of Kyoko's attacks and manages to transform herself into a masō-shōjo, which brings Ayumu to the conclusion that it was her who had absorbed Haruna's magic to the strength of her own. Taking the fight elsewhere, Eucliwood uses the power of her words to kill Kyoko over and over. However, Kyoko manages to stop this by tearing her eardrums and attacks Eucliwood with a powerful explosion which knocks her unconscious. Resolved to protect Eucliwood, Ayumu manages to get up close and negate Kyoko's magic, before killing her down to her last life, which he decides to spare. Dai-sensei appears to take Kyoko home to reeducate her, when another evil presence possesses Kyoko and escapes with her. Eucliwood mentions the presence was that of a zombie that she was forced to kill when it was consumed by malice.
