In Bleach, Shocking Shin'ō Academy

Yu Chen transmigrates into the world of Bleach and becomes a student at Shin'ō Academy, in the same class as Rukia.

On his first day, he shocks everyone.

He challenges Tōshirō, and poor little Tōshirō is nearly beaten into a breakdown.

From then on, the Gotei 13 is abuzz with rumors that someone capable of surpassing Captain-Commander Genryūsai Shigekuni Yamamoto has been born.

Aizen: “Impossible. Why is Kyōka Suigetsu ineffective? And why is even the power of the Hōgyoku so insignificant?”

Yhwach: “Why was the Sternritter wiped out in an instant? Why does The Almighty show me nothing but death?”

The Soul King?

Sorry, even the cornerstone of the world is powerless against Yu Chen.

Because I will be a being above all things.
