begins 20 years after the strongest hero on Earth meets his demise. The world believes that the hero died and will never return. Little do they know that the hero has been trapped in a parallel dimension all this time and has finally found a way back to exact vengeance on those responsible for his fate.
Two decades later, strange phenomena begin occurring across the world – catastrophic disasters, monster sightings, and paranormal events.

The world descends into chaos as humanity struggles against threats beyond their control or comprehension.

After a fierce and destructive battle, the son manages to awaken the last vestiges of the hero’s former noble spirit. Confronted by the person he cherishes most, the hero recognizes how far he has fallen. In the end, the hero sacrifices himself to undo the damage he wrought, dying once more as humanity’s champion.
Overall, ‘Return of the Disaster-Class Hero’ is a poignant manga that explores how good intentions can pave the road to hell and how even a beacon of hope can be twisted by cruelty into a weapon of vengeance. At its heart, it is a story of redemption and sacrifice.
