ヘルミリア＝ヴァン＝ノクスローゼ

Having once ruled the Magical Kingdom of Ragnarök for a thousand years, she is the Demon King among Demon Kings (self-proclaimed). Feared throughout the ages under titles like "The Millennium King" and "The Immortal Rose" (self-proclaimed). Currently a second-year student at Kamui Academy. She skips classes and can’t even be bothered to properly participate in world-saving hero duties, spending most of her time lazing around playing games in her room. A problem child, a shut-in, and a slacker of a Demon King. She frequently clashes with Hinagiku, a living manifestation of justice. Ability: "Resplendent Twelve Apostles" The power to summon and command across worlds twelve Demon Kings who once served her. Essentially a summoning spell. Her favorite is the Dragon King Exus—she finds his black-and-white pattern adorable. [Translated from official website]
