Lydia Beginsgate

Lydia is a Hero who lived during the mythological era, serving as the most trusted ally of the Great Demon King Valfades before his reincarnation. Renowned for her extraordinary fighting ability, she carried a bold and carefree personality, though her habit of teasing young women revealed a more mischievous side. In the past, after falling under the influence of brainwashing, she met her end at Valfades' own hands, with her soul thereafter bound within a cursed magic sword. As one of the rare few who truly understood the solitude the Demon King bore, she shares a profound bond with the protagonist that transcends three thousand years.
