I, who served as a Holy Knight—the most admired profession in the royal capital—was expelled from the Knights Order. To make matters worse, I learned of the relationship between my childhood friend, the Saintess Cecil, and the Prince.

Though filled with despair, that very night a special skill called "King of Heretics" manifested. This unique ability allows me to "appraise" heretics and gain their loyalty.

Utilizing my newly manifested skill, I gather comrades who admire me and will rise to become the boss of a dark guild. The Saintess Cecil seems to be searching for me, but I will simply forge my own path.
