The Empire Useless Youngest Prince

Rei Satoru had everything a brilliant man could ask for: a successful career, an exceptional eidetic memory, and a mind capable of turning knowledge into power.

Until exhaustion finally caught up with him.

After a fatal car accident, Rei expected nothingness.

Instead, he opened his eyes as Luxien Altair Orion, the nineteen-year-old youngest prince of the Grand Empire Orion.

And unfortunately...

Luxien is known as the Empire's Useless Youngest Prince.

Born with a fragile body and plagued by chronic illness, Luxien has spent most of his life confined to the secluded East Wing of the Imperial Palace. Unlike his powerful siblings, he possesses neither the strength nor the physical condition expected of an Imperial Prince.

Yet behind the rumors lies a truth Rei never expected:

Luxien possesses a perfect memory, preserving everything he has ever seen, heard, and read. Combined with Rei's experience, strategic mind, and determination, the supposedly useless prince suddenly possesses an extraordinary advantage.

Then Rei discovers something hidden within his soul.

A vast library.

An ancient Chronicle.

And a mysterious voice that calls him Guardian.

As Rei begins uncovering forgotten knowledge, ancient Covenants, political secrets, and mysteries buried within the Empire's history, his quiet second life quickly becomes anything but peaceful.

Because someone is already trying to kill the youngest prince.

And the more Rei learns about this world...

The more he begins to suspect that his arrival was never an accident.

The Empire's Useless Youngest Prince is a character-driven fantasy of imperial intrigue, ancient magic, kingdom-building, mythical creatures, family, and destiny, with a very slow-burn BL romance woven naturally into the journey.
