The Unnoticed Strongest Job: Rule Breaker

After dying in a traffic accident, Hikaru finds himself in the afterlife, but instead of judgment, he receives an offer to be reincarnated into another world. His new ability is the "Soul Board," a skill tree system that allows him to enhance skills by spending points. However, this reincarnation comes with a condition: he must kill someone within an hour, or his soul will be destroyed. To survive, Hikaru focuses all his points on stealth skills, becoming an unparalleled master of concealment. This story follows a boy specializing in stealth as he uses his skill tree to become incredibly strong in a new world.
