I Became a Cheat-Level Skill Thief

Once dismissed as a failure, Crash is betrayed by his companions and pushed to the brink of death. He gains one chance to return to the past, though he can never use the regression skill again. With knowledge of the future from this single do-over, Crash sets out to save the world from destruction and take revenge on those who trampled him in his previous life. He steals skills, refines them, and gathers more, awakening as a skill thief whose abilities surpass even cheat-level powers.
