Yobidasareta Satsurikusha

Tohno Hifumi is abruptly summoned to another world by a kingdom seeking a hero, but the summoners make a fatal miscalculation. Beneath his outward appearance lies a man who spent years using martial arts not to fight, but to suppress his deeply ingrained killer instincts. Furious at being kidnapped and dragged into an unfamiliar realm, Hifumi unleashes the very violence he had worked so hard to contain. In a swift and brutal display, he slaughters the knights sent to receive him and murders the King—the mastermind behind the summoning ritual—punishing them for their arrogance. Amidst the carnage, the Princess stands as the sole survivor capable of maintaining her sanity and acting rationally. Recognizing that any further resistance would only result in more senseless death, she makes the pragmatic decision to release Hifumi rather than provoke him further. With his restraints finally shattered, Hifumi embarks on what he considers a thoroughly enjoyable journey across this strange new world. No longer bound by the discipline he once forced upon himself, he travels freely, unrestrainedly killing anyone foolish enough to stand in his path.
