On a seemingly ordinary school trip, Yogiri Takatou takes an ill-timed nap and wakes up to a nightmarish scenario: he and his classmates have been transported to a fantastical world by a sage who gifts most of them with special abilities. However, Yogiri and his classmate Tomochika Dannoura are not only excluded from receiving these 'Gifts' but are also abandoned by their peers to fend off a deadly dragon. In the face of imminent death, Yogiri unexpectedly discovers his own extraordinary ability — the power to kill anything instantly. Together, Yogiri and Tomochika must survive in a world that holds constant dangers, using his 'Instant Death' ability to protect themselves and possibly, find a way home.

As Yogiri and Tomochika journey through this strange world, they encounter various adversaries who underestimate the young man’s lethal power. With each confrontation, Yogiri's resolve is tested, forcing him to make challenging decisions about whom to trust and how to use his power without compromising his morals. Meanwhile, the origins of their transportation and the intentions of the mysterious sage slowly unravel, compelling Yogiri to question everything he knew about his life and his newfound role in this otherworldly adventure. Amidst conflicts and revelations, the duo's bond strengthens, turning their desperate attempt to return home into a quest that could change the very fabric of both worlds.
