Read manhwa The Hero's Younger Brother Is a Deceased Person in the Academy online in English. Also known as The Little Brother Is the Academy's Hotshot, My Little Brother Is The Academy's Hotshot, and 용사 동생은 아카데미 고인물.

Rudd Denatos has spent his entire life overshadowed by his older brother Aesir, a legendary dragon slayer whose genius and strength define their family's legacy. When a catastrophic final battle with the dragon king claims both Aesir's life and countless others, Rudd is sent hurtling backward through time. He awakens as an academy cadet once more, but something is terribly wrong—his brother no longer exists in this past, erased as though he never was. Armed with memories of the future and desperate to prevent tragedy, Rudd assumes his brother's identity to fill the void left behind.

At the academy, Rudd must navigate a world where he's expected to be the prodigy his brother once was, all while secretly preparing for the inevitable return of the dragon king. As he masquerades as Aesir, earning admiration and respect through skills and knowledge beyond his peers, he grapples with unanswered questions about what happened to his brother and why he alone remembers a different timeline. The pressure mounts as the Seventh Dragon—the most powerful threat of all—draws ever closer, and Rudd realizes his greatest challenge may not be defeating dragons, but uncovering the truth hidden within the fractured fabric of time itself.

This series may appeal to readers who enjoy time-travel mysteries, action-packed fantasy adventures, academy settings with high stakes, and stories exploring identity and sacrifice.
