Dokushin Kizoku: Danjohi 1:99 Sekai no Akuyaku Reisoku

Takayuki Shinohara, a 32-year-old librarian, never imagined that an ordinary day could upend his entire life. When a sudden earthquake strikes, the world around him gives way—and he awakens in a completely different realm. Not only has he been transported to another world, but he now finds himself in the position of a high-ranking noble's son, cast into a life of privilege and peril far removed from his quiet days among the bookshelves. His new existence begins under the worst possible circumstances: he opens his eyes at the very moment his own engagement is being called off. Thrust without warning into noble society, where polished smiles conceal ambition and deception, Takayuki quickly realizes that merely surviving among the aristocracy will require far more than a prestigious family name. Fortunately, he holds one decisive advantage—a skill that allows him to read the minds of those around him, exposing hidden motives and buried secrets with every exchange. Armed with this ability, the former librarian resolves to leave his mark on his new world. This reincarnated-noble fantasy weaves together intrigue, adventure, and the promise of a second chance at greatness.
