Bleach: I Became the Strongest Across the Heavens by Picking Up Rukia

Reborn in the world of Bleach, Kurokawa Shin wakes up from the start lying in a pile of corpses.

Fortunately, his System awakens from the start, granting him the ability to “copy traits.” But in the cannibalistic Rukongai, he decides to keep his head down for now.

That is, until he finds a baby girl named Rukia.

From then on, he holds a child in one arm and a sword in the other, quietly growing stronger in the Myriad Worlds while frantically copying traits.

The ocular techniques of Naruto, Haki from One Piece, Breathing Styles from Demon Slayer, magic from Fairy Tail...

When Rukia grows up and enters the Shin'o Academy...

When Aizen's schemes quietly unfold and the shadow of the Quincy looms once more, Kurokawa Shin no longer hides.

With the force of a thunderbolt, he sweeps away every enemy.
