After enduring relentless power harassment and a constant barrage of insults from the Imperial Princess Lysithea, the butler Alm finally decides to resign. Branded “incompetent” for years, he had in fact been the one single-handedly handling every impossible demand the princess threw his way, a masterful butler whose true abilities went completely unrecognized. Leaving the Empire behind, Alm is taken in by Princess Bridget of a neighboring kingdom, affectionately known as the Sunflower Princess. In this new land, free from constant abuse, Alm begins to reveal the extraordinary, out-of-the-ordinary skills he had long kept hidden. Whether solving impossible problems or protecting those under his care, his talents quickly prove to be far beyond ordinary. Determined to safeguard the princess who gave him a new home, and the place where he finally belongs, Alm steps forward once more. Thus begins the story of the world’s strongest butler, rising to protect his new master and carving out a future where his true worth can finally shine. https://www.cmoa.jp/title/293089/
