"The Sword of the Spirit"

His fame continued to grow, and legends of his power spread beyond Japan's shores. Renji traveled to the islands of Okinawa, where the final blade of legend awaited him—the Tama-no-Ikutsushi, the Sword of the Eternal Waters. This blade was said to be a gift from the sea god, and whoever wielded it could summon the oceans and control the tides themselves.

To find it, Renji sailed into the heart of the ocean, where a hidden underwater temple rose from the depths. Beneath the waves, a great serpent—the guardian of the sea—waited. Renji dove into the depths, confronting the serpent in an ancient trial of water and spirit. The serpent tested his strength by summoning whirlpools, tidal waves, and storms from the depths.

Renji drew upon the combined power of his other blades, using the wind to calm the storms, the fire to banish the cold depths, and the earth to steady the sea. The serpent, recognizing Renji's mastery, yielded the Tama-no-Ikutsushi.

As Renji raised the sword above the water, the sea parted, revealing a world of beauty and power. With the sword, Renji could call the tides to rise, calm the oceans, or create a barrier of water so strong it could stop armies in their tracks.
