His "classroom" connects the world's most elite "problematic beauties"! At the outset, the safe house "picks up" a young girl who's recently lost her sister and is filled with hatred. Faced with her murderous intent, Lin En gives her a single assignment: "Go back and face your anger!" As Shinobu Kocho unleashes bloodshed across the Demon Slayer world with this "assignment," Lin En uses his first reward, "Emotion Perception," to precisely tap into Yukino Yukinoshita's loneliness! → Homura Akemi: From "Desperate Girl of Reincarnation" to "Demon God Who Controls Time and Causation," rewriting fate and subverting the universe! → Misaka Mikoto: From "Sinful Princess of Electricity" to "Thunder Empress on the Path to Absolute Power," piercing the divine realm with lightning and reshaping the order of Academy City! Of course, there's also the occasional everyday pretty girl... This world is truly wonderful, but sometimes it's just too much...

A famous figure in history, the third friend of the Most Ancient King, the first prime minister of Mesopotamia, the man favored by the Greek gods, the king of giants in Northern Europe, the incarnation of God who awakened Solomon's humanity in Israel, assisted by Prince Camelot... The young but weathered-looking Lovi sat on the top of the Fuyuki Bridge, sighed, and looked at the scene in front of him: "Tell me, what went wrong here?" "Or, you kill me and let me ascend to the Throne of Heroes? Please!"

The hand holding the cigarette trembled slightly.
