Bleach: Kenpachi Kicks the Soul King, and Aizen's Story Begins

He transmigrates into the world of Bleach and gets bound to a sign-in System. He thinks he can just check in every day and coast to victory, but the sign-in rewards are bizarre: a roasted sweet potato grilled by Captain-Commander Yamamoto himself, a... mysterious item from Retsu Unohana, and a bound volume of Seireitei Communication.

Where are the god-tier weapons? Where's the power to crush everyone in an instant?

Then he gets his monthly sign-in reward: the exclusive Reishi Affinity trait, which doubles his training speed. Even more absurdly, after he raises Sōsuke Aizen's trust level to the required threshold, he triggers a character sign-in and obtains the Heart of a God, which maxes out all his learning abilities to the limits of his current level!

At last, the perspective of a genius opens up to him.

But then there's a problem: his Zanpakuto refuses to answer him. While others meditate with their swords, he worships his. While others pray, he offers sacrifices to himself. After all that, his spiritual pressure skyrockets to Captain-level, and he shakes the men's dormitory into a ruin, leaving him with a bill for 390,000 kan.

Even more exciting, Yoruichi Shihōin chases him around to beat him up, Retsu Unohana watches him with a smile, and Aizen calls him brother every day.

All he wants is to keep a low profile and grow stronger. But this world just won't give him a break.
