The first time around, Kaizan Lovellon spent nearly thirty years swallowing his anger and enduring the prejudice aimed at him as an illegitimate son with barbarian blood.

It got him nowhere.

After the world fell apart and Kaizan was killed on the battlefield, he wakes up ten years in the past, right before entering the academy.

This time, he's done trying to be nice.

The obedient persona disappears almost immediately. Arrogant nobles get put in their place, his cursed engagement becomes a convenient source of expensive elixirs, and Kaizan starts making full use of the strength he spent his first life suppressing.

Unfortunately, the people around him aren't quite sure what to make of this new Kaizan.

His fiancée is confused. The empire's powerful figures are taking notice. And the man everyone once dismissed as a meek illegitimate son is rapidly becoming someone nobody can afford to ignore.
