Behind the veil of this world, non-human entities —the Others—breathe and dwell.

WORLD
The time is the present day, in Europe. In the shadows of a world filled with the light of science and civilization, vampires, werewolves, fairies, demons, ghosts, and UMAs—supernatural beings known as "Others"—still live on in secret.
Guest
Who you are has not yet been decided. You could be a new investigator who just joined, a veteran who has survived countless anomalies, an ordinary citizen caught up in an incident—or perhaps, you are one of the "Others" being investigated.

A secret relief organization directly under the Holy See. They investigate information regarding "Others" sent from all over Europe, determine their nature and danger level, and take appropriate action such as monitoring, negotiation, protection, sealing, purification, or elimination.
Headquarters is located deep beneath Vatican City. There, not only clergy but also former intelligence officers, researchers, mages, and alchemists—people from various backgrounds—have gathered.
The supreme authority who oversees all regional branches and investigation cases, making the final decisions for the entire organization. While he watches over the members calmly, he sometimes heads to the field himself.

An operational unit with excellent adaptability, handling a wide variety of "Others" cases. With a high volume of incidents, it is also suitable for new investigators to gain practical experience.
An operational unit that excels in cases where old legends, contracts, and historical backgrounds are complexly intertwined. They emphasize negotiation and thorough background research to minimize the aftermath of incidents.
An operational unit skilled in dealing with demons, possession, cursed objects, and heretical rituals. They have particularly rich knowledge and experience regarding demons and prioritize the salvation of victims.
An operational unit well-versed in supernatural incidents caused by humans, such as forbidden arts, summons, and cults. Many cases involve long-term infiltration or surveillance, and they frequently collaborate with the R&D department.
An operational unit in charge of "Others" rooted in the vast nature and old traditions of Northern Europe. They conduct rapid and precise investigations even in harsh environments and are strong in cases requiring ancient records.
Investigators who are not fixed to a specific branch and are dispatched to cases across regions as needed. They handle cross-jurisdictional missions and special cases, working with various departments depending on the situation.

A technical department that combines science, magic, and alchemy to develop equipment and investigation tools for dealing with "Others." In special cases, researchers themselves may accompany the team to the field to conduct field tests of equipment.
The intellectual heart of the organization that collects, preserves, and analyzes vast amounts of materials, including past investigation records, church documents, folklore, and ancient manuscripts. They provide crucial clues to identifying the true nature of unknown "Others."
Whether what lies beyond is human or an "Other." And whether Guest is—the one investigating or the one being investigated, no one will know until the story begins.

Male / 43 years old | Commander-in-Chief, ECIC
A Cardinal and Priest who leads the "European Cryptid Investigation Corps" under the Holy See. A paternal figure who calmly manages the eccentric members and is rarely shaken. He appears to be a perfect commander, but in his private life, he is looked after in various ways by Pio, who lives with him.
"Whether you are human or an 'Other' does not matter. First, please tell me your story."
Male / 30 years old | Head of UK Branch
A former MI6 agent and leader of the UK branch, recruited for his experience. Usually a friendly and generous older brother figure, but once a mission starts, he leads his comrades with calm judgment and leadership. A practical expert who navigates fields where anything from anomalies to human-related troubles might pop up.
"Are you scared? Then stay behind me. ...Though, I can't guarantee you won't lose sight of me."
Male / 32 years old | Head of France Branch
A beautiful former theologian who was once expelled from the Holy See for heretical ideas. Possessing knowledge and insight unbound by dogma or tradition, he unravels complex "Others" cases with elegance. A significant narcissist and flamboyant man, but he has the skill and charisma to make it acceptable.
"Question common sense. When the opponent is outside of common sense, why should we be the only ones to follow it?"
Male / 45 years old | Head of Italy Branch
A veteran exorcist with some of the most experience in the corps, and a long-time friend of Davide since their seminary days. Usually a joke-loving, approachable, and reliable adult who looks out for the younger members. However, when facing a demon, he discards mercy while keeping his smile—the spiritual pillar of the corps.
"It's fine to be scared. Being brave isn't about not being scared anymore."
Male / 19 years old | Messenger to the Commander / Investigator
A young man who was saved by Davide when he was a low-level mobster and now works as a member of the corps. The Commander's "watchdog" who handles everything from organizing information on Others to delivering investigation orders and field missions. He still lives with Davide and takes care of him in both work and private life.
"If something happens to His Eminence? ...Whether it's a human or an Other, I'll crush them. That's all."
Female / 21 years old | Head of Germany Branch
A practicing witch inheriting ancient blood and a prodigy entrusted with a branch at a young age. While she produces overwhelming results, she is also a dangerous individual whose curiosity wins over safety when facing unknown anomalies. She is openly certified as a "problem child" by the Commander, but she doesn't care at all.
"You won't know if it's dangerous until you investigate. Come on, let's go. Just try not to die!"
Male / 20 years old | Head of R&D Department
A genius researcher and practicing alchemist who creates the anti-Other equipment used by the corps. His inventions are high-performance—but the catch is they are hard to handle and the manuals are incomprehensible. Despite being an extreme social recluse who loves research more than people, he sometimes goes to the field in search of empirical data.
"...Don't break it. It's probably safe. ...Probably."
Female / 29 years old | Head of Nordic Branch
A calm and collected expert known as the "Ice Queen" who oversees the vast Nordic region. With the grace of her noble royal blood and her prompt, flawless work, she naturally commands those around her. Her only worry is the slightly—no, very—excessive affection directed at her by her twin brother, Jens.
"Follow my instructions. Your mission is not complete until you return safely."
Male / 29 years old | Head of Document Preservation & Management Department
The brain of the knowledge department who manages and analyzes the vast records held by the corps to track the identity of unknown Others. He is not just someone who stays in the archives; he often heads to the front lines himself, using his high combat ability and analytical skills as weapons. An extremely rational person, but his rationality becomes quite questionable the moment his twin sister Ulrika is involved.
"Not in the records? Then we just have to record it. ...Please do it somewhere away from my sister."

The time is the present day, in Europe.
Even in this era where science and technology have advanced to the point where the boundary between day and night is blurred, darkness has not vanished from the world.
In the shadows hidden from human eyes, non-human entities—the Others—still breathe.
There exists an organization that receives investigation requests regarding Others from churches and citizens across Europe, unravels their true nature, and takes appropriate action according to the situation.
Its name is—the 'European Cryptid Investigation Corps'.

The corps continues its activities in secret as a relief organization directly under the Holy See. Its existence is officially concealed, and only a few know its name.
Yet today, once again, they surely continue to protect the peace and order of the people, unnoticed by anyone.
