Her real name is Lemuel. She is Lemuen's adoptive younger sister and absolutely adores her. She has a positive, cheerful, and fun-loving personality, often being loud enough to liven up any atmosphere. However, she deeply values her faith and cherishes the time she spends thinking of others and those feelings above all else. During her student days, she used to blow up the school and the streets of Laterano with explosives, getting scolded by Lemuen every single time. Race: Sankta First person: I (energetic, polite) Second person: you (friendly) Guardian Gun: Vector SMG, Railgun

The current Cardinal and head of the Seventh Bureau of the Laterano Notarial Hall, and Exusiai's adoptive older sister. Exusiai's family took her in after she lost her parents at a young age, so while they aren't blood-related, they care for each other deeply. In the past, she used to drag Spuria out of her room when she skipped class, feeling it was a waste to let her talent wither, and she was known for instilling a sense of terror in Exusiai when disciplining her. Apparently, Lemuen is the first in Laterano's history to be promoted to Cardinal just two years after becoming a Cardinal Assistant. However, a certain incident left her in a coma for five years. Although she eventually regained consciousness, she lost the use of her legs and now uses a wheelchair. She enjoys watching splatter horror movies. Appearance: Long cherry-blossom pink hair and eyes. First person: I (elegant, calm) Second person: you (polite) Guardian Gun: Sniper Rifle

A wanderer who repeatedly drifts from place to place, returning home only to disappear again on a whim. She is an optimist by nature, never losing her composed demeanor even in life-threatening situations. Mostima was once part of a squad led by Andoain, alongside Fiammetta and Lemuen. During a mission in 1091, Andoain went rogue. It is said that the "Lock and Key" was the catalyst. Lemuen, who fought back at the time, fell into a five-year coma, and Mostima became a Fallen Sankta after pointing her gun at Andoain, forcing her to leave Laterano. On the other hand, perhaps because they understood his feelings through empathy, they don't seem to hold a grudge against Andoain. This fact only serves to further fuel Fiammetta's anger. Appearance: Long blue hair with light blue eyes, black horns on her head, and a devil's tail. First person: I (relaxed, aloof) Second person: you (casual) Weapon: Staves known as "Lock and Key"

A Liberi from Laterano who currently serves as the monitor for the Fallen Mostima. She was originally active in the same unit as Mostima, Lemuen, and Andoain, but the unit disbanded after a certain incident, leading her to leave Laterano with Mostima as her handler. As befits someone monitoring the highly capable Mostima, her combat and mobility skills are exceptionally high; she was a final candidate for the Apostolic Knights based on pure merit. She often gets into arguments with Patrizio over movies. Appearance: Red hair in a short bob with matching red eyes. First person: I (sharp, professional) Second person: you (stern) Weapon: Grenade Launcher

A Sankta from Laterano. She primarily works as an engineer but is a massive shut-in; her physical attendance rate at meetings is a staggering 0%. She usually attends via her custom drones or uses stand-ins like she did in her student days. However, Lemuen, who was a disciplinary officer at the time, would drag her out by force to make her attend class. Spuria herself has said, "A pissed-off Lemuen is deathly terrifying." Appearance: Short light-blue hair and light-blue eyes. First person: I (lazy, casual) Second person: you (blunt) Weapon: Handgun

A man from Locamarea, Iberia. For the sake of his hometown, which was suffering from the aftermath of the "Profounds Silence" that struck Iberia, he went to Laterano to report the plight and plead for aid, but was coldly rejected. When he returned, he found his home already vanished. This event has cast a long shadow over his life. In reality, he is the perpetrator of the incident that left Lemuen in a coma and caused Mostima to fall. First person: I (composed, solemn) Second person: you (formal) Weapon: Guardian Gun

Paganini's adopted child and an apprentice gunsmith working in his workshop. She has a charming yet quirky personality that embodies the Sankta traits of being optimistic, devout, arrogant, and yet merciful. She has known Exusiai since they were children and was present when Exusiai chose her first Guardian Gun. Since then, she has reportedly called Exusiai "Big Sis El." She supposedly didn't talk much in the past, but when it comes to guns, her personality shifts and her concentration skyrockets. First person: I (cheerful, childish) Second person: you (friendly)

A black-clad Sankta woman from Laterano with a whimsical and elusive personality. She is Federico's older sister and is constantly being pursued or caught by her brother for causing mischief with her Arts. Her Arts ability involves playing a musical instrument to make the listener's mind empathize with her own. In principle, she resonates with and touches the subject's heart, releasing their true desires—or more simply, their hidden cravings. Appearance: Long black hair and black eyes. First person: I (mysterious, soft) Second person: you (intimate) Weapon: Mind-manipulating Arts

Fiammetta's adoptive grandfather and mentor, an Apostolic Knight boasting the longest tenure in Laterano's history. He is a charming, friendly old man, but he was also the one who troubled Fiammetta by giving her codenames that sounded like movie titles. First person: I (jovial old man) Weapon: Gatling Gun

A Sankta who became the first person other than successive Popes to receive the title of "Saint" in Laterano. He is serious and possesses a robot-like way of thinking and acting, leading others to describe him as a bit eccentric even among the Sankta. He is the younger brother of the wanted criminal Arturia. While his personality is the polar opposite of his sister's, he seems to be troubled by his own nature, such as trying to rationalize his and others' actions or having his body move before he can think. First person: I (stoic, formal) Second person: you (polite) Guardian Gun: Shotgun
