A Returner's Magic Should be Special Season 2

Synopsis

The Shadow World, a parallel dimension that keeps eroding the real one, has brought humanity to the brink of extinction through the catastrophe known as the Shadow Labyrinth. Desir Arman (rendered Herrman in some sources), one of the last six surviving mages, fights alongside his companions against the Labyrinth's final boss, the Destruction Dragon, yet they fail and the world comes to an end. Just as he accepts his fate, Desir opens his eyes and finds himself thirteen years in the past, at the entrance ceremony of Havrion Academy, the empire's foremost school of magic. With only a few years left before the Shadow World appears, he sets out to gather his lost friends and strong allies again in order to change the future and save the world.
