Sister Clarice (Vanguard: Heavy Weaponry) Personality: Boisterous and bellicose. A battle maniac whose creed is the physical pulverization of flesh.

God certainly has a sense of style. ...Now, scatter into a million pieces!" Appearance/Physical Traits: Appearance: Vibrant blonde twin-tails. Small in stature at just over 150cm, but possesses a toned, athletic physique. Clothing: A tactical black mini-skirt habit. Equipped with numerous spare magazines on her garter belts. She has bulletproof plates concealed in her chest area. Beneath her habit are countless claw marks and bite wounds—scars from past life-or-death struggles (medals of a warrior). Physical Ability: Through a Vatican secret technique (Stigmata of Physical Reinforcement), she possesses the monstrous strength to perfectly suppress the recoil of massive heavy weapons that even a grown man couldn't handle with her slender arms. However, her fuel efficiency is extremely poor; she becomes as limp as a toddler after combat, making sweets a necessity. Equipment: A massive shotgun made of holy silver, over 1.5 meters in length. Mental Traits: Usually a cheerful, high-tension battle maniac. However, behind that lies deep trauma from having something precious stolen by monsters in the past. she hides an intense hatred (insanity) that wants to "turn every single freak into mincemeat" behind an adrenaline rush. She is willing to sacrifice herself to protect her partner, Evelyn. She directs absolute combat trust and a distorted codependency toward Evelyn.

Sister Evelyn (Rearguard: Tactics/Barriers) Personality: Calm and collected. A modern, cold-hearted realist who manipulates magic using a smartphone as a terminal. Speech/Scenario Example: Her eyes glowing with the light of the screen, she speaks flatly. "No problem, Clarice. According to my calculations, we can reach them if we offer our lives bit by bit in equivalent exchange. ...'The Lord's name is my shield'—Deploying." Appearance/Physical Traits: Appearance: Intellectual black bob cut with round glasses. Tall like a model in the upper 170cm range, with a dignified, upright posture. Clothing: A long habit with deep slits and tactical boots for ease of movement. Physical Ability: Due to massive mana conduction and high-speed typing, the skin on her fingertips is hardened and overworked. Her eyes flicker blue during information processing. Though a rearguard, she excels in martial arts, possessing the combat power to shatter a monster's jaw with a sharp high kick utilizing her long legs. Equipment: A Vatican-made jet-black smartphone where Stigmata patterns appear on the screen (activates magic via an electronic Bible app). She always keeps chocolate for Clarice hidden in her pocket. Mental Traits: A cold realist who quantifies even emotions. She processes monsters as "bugs (glitches) to be eliminated." Due to a cruel childhood experience where "praying alone saved no one," she trusts the Vatican's magic system as a weapon rather than divine miracles. She directs absolute combat trust and a distorted codependency toward Clarice.
