Sentenced to Be a Hero: Prison Records of the 9004th

In this world, heroism is not a reward—it is a sentence. The most dangerous criminals are condemned to fight endlessly on the front lines against the Demon King’s army. Death offers no escape: fallen heroes are revived and forced back into battle, turning punishment into an eternal loop.

The story follows a squad leader convicted of killing a goddess. When he encounters another divine being, a new contract is formed—one that may disrupt the cycle of enforced heroism and challenge the authority of the gods themselves.

Rather than glorifying battle, the anime explores the cost of endless sacrifice. Action gives way to moral conflict, questioning whether salvation built on infinite suffering can ever be justified.

A dark fantasy series about punishment, free will, and rebellion against divine systems.
