In the twilight of his legendary life, Inglis, the Hero-King, yearns for only one thing: the chance to live again solely to master his martial arts without the crushing burden of ruling a kingdom. Granting his dying wish, the Goddess Alistia reincarnates him into the
distant future as Inglis Earcus, the infant daughter of a minor noble family. Much to his joyous surprise, Inglis discovers he was reborn as a female. Unfazed by this biological shift, Inglis retains his memories, immense magical power, and unwavering ambition to reach the absolute pinnacle of swordsmanship.As Inglis grows, her astonishing abilities quickly manifest. However, the world she has inherited is drastically different. Humanity is plagued by monstrous ethereal beasts called Lesser Lesser, which are kept at bay by massive floating castle towns and a specialized military force. A pivotal moment arrives at Inglis’s coming-of-age ritual, where her lack of a traditional Rune initially bars her from
military training. Undeterred, she uses her overpowering ether control to manifest a divine weapon and brutally defeats a rampaging demon, cementing her prowess and earning the protection of the knight commander.Inglis soon befriends Rafinha Bilford, her cousin and a gifted young squire with a powerful Rune. Bound by a deep, affectionate sisterly bond, the duo enrolls in the royal knight academy in the capital city of Carlaw. Academy life, however, is merely a backdrop for Inglis's relentless pursuit of worthy opponents. Her immense strength continually attracts danger, drawing the attention of both corrupted noble factions and terrifying Highlander elites who manipulate the lesser beasts from the shadows.Throughout her adventures, Inglis repeatedly clashes with a mysterious terrorist organization seeking to disrupt the fragile peace between humanity and the Highlanders. Despite these grand geopolitical conflicts, Inglis’s personal motivation remains singular and delightfully selfish: she cares nothing for saving the world for its own sake, but rather wants to keep it intact solely so she can continue fighting strong adversaries. Alongside Rafinha—who eventually masters a legendary mecha-like artifact—Inglis confronts increasingly formidable foes, including ancient dragons and corrupted knights. She shatters every limitation placed upon squires, turning every battle into a thrilling step toward her ultimate dream of becoming the supreme martial artist, perfectly content as an extraordinary female squire who views the world's greatest threats merely as stepping stones to her own physical perfection.
