In a world devastated by sudden warp gates that bring demonic entities to wreak havoc, power defines everything. Guilds control society, raids are spectacles, and rank determines a person’s worth. Akira Tsukishiro was a nobody. A weak mage who died with full of regret and unfinished choices, he awakens to find himself back in his teenage body—given a chance to redo the life he wasted. The only proof of this miracle is a strange clock pendant, with a ability to briefly defy time itself, at a steep physical cost. Determined not to repeat his past, he trains relentlessly, avoids the paths that once broke him, and begins to move through the world in ways he never could before. Yet, something was unfathomably disturbing, the events of past change and he slowly loses something human. As he walks his path, the line between human, demon, and legend slowly blurs. This is a Regressor’s Guide to second chances, hidden consequences, and how far someone can descend to fix their life.
