The Strongest True Ancestor

A certain shut-in transmigrates into the world of Strike the Blood and accidentally devours the Original, Agulola, becoming the Fourth Primogenitor. Before he can even celebrate, Gaia lures him with promises of gain and spirits him away to the Nasuverse, where he becomes the eldest son of the Ryougi Family and fights to prevent the Land of Steel.

The Twenty-Seven Dead Apostle Ancestors, heroic spirits, and magi are all nothing more than stepping stones.

With an immortal body, he commands the Twelve Calamity Beasts and spreads the gospel of darkness across the anime multiverse.

Yet his true nature is...

"Once I buy German Orthopedics, I'll become a man who can enter and leave the Root whenever he wants!"

The protagonist isn't a self-sacrificing saint, so enjoy without worry.
