魔女の下僕と魔王のツノ

Betty, an apprentice witch struggling with broom-riding, is on a mission to create a cure for her mentor Vivian's mysterious illness. To complete the potion, she needs the horn of the fearsome Demon King, King Bull. Enter Arsenio, Betty's loyal and soft-hearted servant, who wields a gun and is willing to do anything to make her smile. Determined to help, Arsenio ventures alone into the Demon King's castle, where he encounters Ray—a clumsy yet curvaceous girl who turns out to be a boy transformed by magic. Together, they face the Demon King and unravel secrets tied to Arsenio's past. (Unreviewed summary by Grok 2)
