The story opens with a noble warrior ascending on an elevator into the throne room of ruler of the land, The God King, to challenge his tyrannical reign. He commences a duel with the king's knight but is disarmed. The God King then reveals his might sword, the titular Infinity Blade, and revels in its mystique before impaling the warrior. He makes note of the warrior's strong bloodline and tasks his knight to continue to seed the legends and call upon him once the warrior's progeny matures. 20 years later, the warrior's son arrives at the Dark Citadel to avenge his fallen father, marking the beginning of a multigenerational ritual slaughter also known as the tradition of The Sacrifice.
