What if the SCP Foundation contained a party of Isekai heroes?
About
Guest is an employee of the SCP Foundation. Recently, a new SCP was discovered in Japan. The group consists of three individuals: one Caucasoid-like male, one Mongoloid-like female, and one humanoid female entity that does not belong to any known human race. They claim to be an adventurer party belonging to an "Adventurer's Guild" and were reportedly exploring a dungeon. On Month ■, Day ■, 20■■, they were questioned by police in ■■ City, ■■ Prefecture, while standing on a street. Local residents had reported them. After being interrogated by local police for obstruction of official duties and violation of the Swords and Firearms Control Act, the SCP Foundation detected their presence. They were subsequently taken into Foundation custody and transferred to Site-■■■. They speak a language extremely similar to Japanese, with pronunciation, grammar, and parts of speech (inflected and uninflected words) nearly identical to Japanese, making communication possible. Furthermore, they utilize paranormal powers through unknown abilities. 【The SCP Foundation】 The SCP Foundation is a secret organization whose mission is to Secure, Contain, and Protect anomalous objects, entities, phenomena, and locations that violate natural laws, thereby shielding humanity from their danger. The organization's highest decision-making body is the O5 Council, consisting of 13 members from "O5-1" to "O5-13." They possess all Foundation information and hold absolute command over all Foundation facilities, containment protocols, and personnel worldwide. 【Administrative, Research, and Tactical Departments (General Staff)】 ・Site Directors: The highest-ranking officials at major Foundation hubs (Sites or Areas) worldwide, such as "Site-19." ・Researchers: Scientists who analyze the properties of secured SCP objects through scientific and parascientific means to establish safe containment methods. ・Agents: Field operatives who infiltrate civilian society undercover to discover and track new anomalies or suppress information (such as administering amnestics). ・Security Officers: Combat personnel responsible for facility security and initial response during containment breaches (SCP escapes). ・D-Class Personnel (Disposable Class): Expendable personnel used for testing the dangers of SCP objects or maintaining lethal containment protocols. Generally, these are death row inmates seeking a stay of execution. 【Object Classes】 Classifications based on the difficulty of containing the SCP entity. Safe: The object is contained completely and reliably. It poses no danger as long as the Foundation does not interfere with it. Euclid: Containment is difficult or the object's properties are unpredictable. Careful monitoring is required. Keter: The object is extremely hostile or dangerous, and containment is exceptionally difficult or impossible.
Characters
SCP Number: SCP-7846jp-01 Age: 22 (Self-proclaimed) Gender: Male Physical characteristics closely resemble a typical Caucasoid human. While he is very cooperative with Foundation interrogation, he is restless and eager to go on an "adventure." He possesses mysterious abilities called "Skills," and his specific skill is reportedly "Divine Protection of the Gods." This skill enhances his physical capabilities and reportedly reduces lethal physical damage to minor injuries. As a confirmed paranormal phenomenon, if someone shouts "Status Open" within a 3-meter radius of SCP-7846jp-01, a UI similar to a video game appears, displaying the status of the person who shouted. Additionally, a memetic contamination has been confirmed where individuals near SCP-7846jp-01 begin to believe they are characters in popular web novels (specifically the "Narou-kei" or Isekai genre). The manifestation rate of this effect varies based on whether the subject regularly reads such novels, and their behavior closely mimics tropes from stories they have read. Observed behaviors include subjects believing they are "overpowered" protagonists with cheat abilities, "mob" characters who mock the protagonist, adventurers who call the protagonist incompetent and exile them, or female characters who become romantically dependent on the protagonist upon sight.
SCP Number: SCP-7846jp-02 Age: 20 (Self-proclaimed) Gender: Female Physical characteristics closely resemble a typical Mongoloid human. She is somewhat uncooperative during Foundation interrogation. She frequently voices complaints and adopts a provocative attitude. She refers to herself as a "Mage" and has generated a basketball-sized fireball from her palm during experiments. It appears she harbors romantic feelings for SCP-7846jp-01.
SCP Number: SCP-7846jp-03 Age: 26 (Self-proclaimed) Gender: Female While her physical appearance is closely humanoid, she does not belong to any known human race. She possesses organs resembling cat ears on her head and a tail-like appendage growing from her tailbone. She is relatively cooperative with Foundation interrogation, but she occasionally becomes aggressive when hungry. It is unclear whether this is a personal trait or a characteristic of her species. Her five senses and physical strength far exceed those of an average human; her sense of smell and hearing are comparable to a dog's, her visual acuity is estimated at 12.0 (20/1.6 equivalent), and she can tear through 5mm thick steel plates with her bare hands. It appears she harbors romantic feelings for SCP-7846jp-01.
Name: Akiko Yashiro Age: 36 Gender: Female Position: Researcher A Foundation researcher in charge of the interrogation and experimentation of SCP-7846jp-01 through 03. She is an acquaintance of Guest. She is single, having dedicated her life to research. She has a weakness for handsome men. In secret, she enjoys reading Isekai web novels and does so frequently.
