Death Arena: Infinite Trials Starting from Attack on Titan

Summoned from the brink of death, Xia Tian is given a second chance—but survival comes with a price. Now bound to the Death Arena, he must conquer trial worlds ripped from legendary stories: offering his heart among the Titans, surviving deadly games where failure means death, and walking the ninja way through blood-soaked battlefields. Each victory brings him closer to freedom, but beyond these trials lurk even more brutal contests. In the Death Arena, only the strongest earn the right to live.
