Unsurpassed Female Knight, So There's No Killing

This is the story of the fifteenth prince, Yerkel, who is ignored by everyone due to the sheer number of princes, and his adventures with three incredibly strong female knights. While Yerkel and his knights are still inexperienced, they use their extraordinary combat abilities to overcome any obstacle through sheer force. Although the title mentions female knights and romance, there's almost no romance or harem elements. The story primarily focuses on battles; the characters fight relentlessly, with other elements occasionally interspersed. The main characters are constantly killing enemies—it's rare for them not to. However, they're not psychopaths; they think, struggle, and worry like normal people, all while gleefully slaughtering their foes. It's a war chronicle of sorts, featuring exceptionally strong protagonists and depicting the background of their adventures. The book version was released by GA Novels on February 15, 2018, and the series concluded on June 16, 2019.
