Regains the Lost Life

Toru Otonashi, who was promised death due to a mysterious disease, believes that a specific medicine will be developed in the future, and goes into an eternal sleep “cold sleep”. But in the future world that he woke up, no drugs were developed, and his body was already a skeleton. Anon, a spirit that suddenly appeared, told him that this world is a fusion of the real world and another world, and he can use magic. Furthermore, Toru, who heard the existence of the magic that can revive the dead, starts to wander the dungeon where the monsters crawl. Source: Micro Magazine
