An ever-righteous and sword-loving high schooler, Fujinomiya Soujirou is fatally stabbed by a robber during a home invasion. However, on the crossroads between life and death, "God" asks him if he wants to live a little longer. Clutching one of his prized swords, Soujirou agrees to a (cheatless) new life. Sent to another world, his only possessions are a talking sword "Hotarumaru" and the sword that took his life, "Sakura". He is also given the job title of "Cursed Sword Master", granting him the ability to bring out the "personality" of a sword. With a new realm of possibilities laid out before him, he sets forth on a journey to raise a harem of katanas, while begrudgingly hunting monsters and helping those in need.
