The Slave of the "Black Knights" Is Recruited by the "White Adventurer's Guild" as a S Rank Adventurer

I worked like a slave in the chivalric order, where all the outcomes were exploited by my senior, but I was scouted by a pretty little girl who called herself a guildmaster.

Initially I accepted it half-jokingly, but after I was shown a great sum of advance payment, I decided to leave the chivalric order. When I went to the guild, even the title of S-rank was prepared.

—This is a success story of a man who has never had a good thing since he was born.
