Fed Up With Being the Spoiled Queen's Genius Butler, I Ran Away and Built the World's Strongest Army manga volume 1 features story by Skyfarm and art by Reiga.

Leet isn't just any butler. His mistress, Princess Kilik, demands the impossible--and he delivers it, seven times before breakfast. But one day, Leet decides enough is enough, and he flees for a neighboring land where the talented rise up through the ranks instead of languishing in thankless, dead-end jobs. Under a new name, Lilt, he enrolls in a training and job placement program, and rapidly discovers that, easy as “wax on, wax off,” his butlering skills make him a valuable asset!
