Yuusha Kei ni Shosu: Choubatsu Yuusha 9004-tai Keimu Kiroku

In this world, heroism is not a noble calling but a severe punishment reserved exclusively for the most heinous criminals. Those condemned to bear the title of "hero" are stripped of their freedom and thrust onto the brutal front lines of battle, forced to fight as expendable soldiers in a relentless war. It is a cruel system designed to weaponize the worst of society, turning their sentences into a bloody struggle for survival where death in combat is merely an extension of their judgment. Among these penal warriors is the leader of the 9004th Punishment Hero Unit, a squad comprised entirely of convicted offenders fighting under the weight of their crimes. Their grim existence takes an unexpected turn when their commander encounters a mysterious goddess. Rather than condemning them further, she offers a pact that defies the very foundations of their reality. The contract forged between the disgraced hero and the divine being sets into motion a chain of events with the potential to fundamentally alter the fate of the world, transforming a tale of punishment into one of unprecedented consequence.
