Marcus, a simple boy, never asked life for anything but one thing:

To see his mother happy... and to protect his little sister from the clutches of life.

He spent his childhood moving between hard jobs, satisfied with little, and content with his small world...

Until the world decided it was time to make him suffer.

One day, he returned to find his home drenched in blood—

A mother who ended her life, and a sister killed without mercy.

At that moment... there was nothing left inside Marcus to break.

He turned into a demon walking the earth, and unleashed his madness, taking brutal revenge on everyone who caused it... and on everyone who stood by watching.

He did not distinguish between guilty and innocent, between child and elder... because everyone is equal in his eyes.

And so... his first life ended.

But it... was not the end, because the heavens did not decide that.

He opened his eyes again in another world—

Inside the Kamado family, as Tanjiro's twin brother.

Will this be a chance for redemption?

Or will it be one of the world's tricks to make him suffer again?
