The Silent Shinigami: Aizen’s Brother

Akira .

A prodigious freshman at the Spiritual Arts Academy, traveling through the world of Shinigami alongside his ambitious younger brother, Aizen Sōsuke, who is obsessed with surpassing him.

With a younger brother pressing him like a relentless rival, Akira constantly feels the weight of expectation and competition. Fortunately, his Zanpakutō, Reiatsu, and swordsmanship—his Zhanquan Zougui—are all exceptionally strong and self-sustaining, requiring no external aid.

【Your Zanpakutō wisdom soars beyond limits, allowing you to master Bankai independently without a tutor.】

【Your Kidō talent is prodigious, culminating in the creation of the forbidden Kidō technique: Fenghou Qimen.】

【Your innate perception of Hakuda is unparalleled; you devised your own forbidden Hakuda technique: Eight Inner Gates.】

【Your swordsmanship qualifications are extraordinary, forging your own unique kendo secrets: The Sword Opens the Gate of Heaven.】

【Your Reiatsu defies norms, enabling you to generate a personal energy source and shatter the conventional boundaries of Shinigami power.】

Yamamoto Genryūsai: I would call him the strongest Shinigami I have ever seen.

Kurosaki Ichigo: Standing before him, I can barely hold my ground…
