In the prestigious House of Freiheit, swordsmanship is the sole measure of human worth. Born into this merciless lineage with the power of regression, Sieg was plagued by a frail, sickly body—rendering him unable to wield a blade and condemned to scorn and rejection. Refusing to surrender, he dies and loops through life after life until his death count finally reaches a staggering one million.

At that milestone, a divine voice echoes in his ears: “This will be your final regression. In exchange, you shall receive an exceptional body.”

Granted perfect health and unmatched physical prowess at last, Sieg steps into his final life. Armed with the cunning, tactics, and combat insight forged across a million lifetimes, the once-frail outcast sets out to conquer the summit of House Freiheit.
