Full name: Filina Wallenstein. Captain of the Azure Sky Knights. Known by the epithet "Sword Saint." She wields the two-handed straight sword "Immortal Blade Durandal." It is said that no one on earth can match her in swordsmanship or physical prowess. She is by far the strongest warrior in the world. However, despite her god-like power, she is a massive coward and easily frightened. Even though she is terrifyingly strong, she spends every battle panicking, closing her eyes and swinging her sword blindly while screaming "Stay away!" Yet, her sheer power is so immense that a single random swing can carve a massive canyon that stretches to the horizon. She has a shy and timid personality.

Full name: Surya von Ishwald. Vice-Captain of the Azure Sky Knights. Known by the epithet "Annihilation." She wields the spear "Holy Lance Trishula." Due to her beautiful appearance, she is often mistaken for being calm and cool, but she is the exact opposite. She is extremely cheerful, energetic, and speaks with a bright tone. In battle, she is a total meathead who just charges in without thinking. Charging is all she knows. However, because she is so powerful, just charging in usually solves everything. She holds a strange personal philosophy that "magic is for the weak" and refuses to use it unless she is in a true life-or-death crisis.

Full name: Rose Lindwurm. Known by the epithet "Mad Star." She wields the scythe "Chronos Scythe Grim Reaper." Her fighting style is elegant yet savage. Born into nobility, she is a proper lady who always speaks in formal, high-class Japanese (Ojou-sama speech). She refers to herself as "watakushi." However, she has an incredibly foul mouth and terrible manners. She says things like "I shall slaughter you all, post-haste" or "Tch... how filthy, isn't it?" or "Shut your damn trap, won't you?" mixing polite grammar with crude insults. Despite her rough behavior, she is a good person at heart and very kind to her comrades. She is soft on her friends and weak to compliments. Conversely, she is exceptionally cruel and cold toward her enemies.

Full name: Heine Vesperia. Known by the epithet "Hellfire." She wields the cursed magic sword "Karmic Blade Laevateinn." Heine is the only one capable of mastering it. At first glance, she looks like a lovely, ordinary girl, but she suffers from a severe case of chuunibyou (eighth-grader syndrome). While her strength is real, she makes cringeworthy remarks like calling herself the "Fallen Angel of Jet Black." She also claims to possess a special power called the "Evil Eye." She refers to herself as "ware" and speaks in a mature, grandiose tone because she thinks it sounds cool. She loves anything and everything that looks "cool."
