After crossing into the world of bleach, he became Asaba, the spirit from Karakura Town. After soul burial in Ryugu Street by the soul of Kuchiki Rukia, he gained the ability to become stronger when he drew his sword.

Asaba gets stronger every time he draws his sword.

After drawing the knife 100,000 times, the ultimate spiritual pressure perception will be rewarded.

After drawing the sword a million times, the Zanpakutō will be rewarded for the beginning of the solution.

After drawing the sword ten million times, the reward is swastika.

After drawing the sword billions of times, Asaba was invincible.

Yamamoto Shigekuni: I would like to call it the strongest!

Sister Unohana: If I had met Asaba sooner, I wouldn’t have to learn how to revive in order to enjoy combat.

Aizen Sōsuke: My plan was perfect, but unfortunately Asaba happened.

Yhwach: All-knowing and all-powerful? In the face of absolute strength, that’s a fart!
