"Primordial Strength", this is not mere physical power, but is the waking echo of Beowulf's legend carved directly into Renji's existence.
When invoked, his body becomes a living saga, muscles surging with an ancient, merciless vitality that predates kingdoms and gods alike.
Every heartbeat sounds like a war drum from a forgotten age, every breath carries the weight of a hero who tore monsters apart with bare hands.
This strength allows him to completely asserts dominance, declaring him as a relic of an era where survival belonged only to those strong enough to seize it.
Under its influence, Renji's flesh hardens into something closer to myth than human.
His bones become unbreakable pillars, sinew coils with explosive force, and his grip holds the certainty of death itself.
Blades will shatter against his skin, impacts that would level buildings would barely slow his stride, and enemies feel an instinctive terror, as if their blood remembers Beowulf's name.
