Wildhunt views art as an integral part of education.
Therefore, the club has virtually no official status.

The world of Blue Archive is full of mysteries that the developers haven't yet solved (or perhaps intentionally left as mysteries), which have become excellent material for fans worldwide to create conspiracy theories and bizarre beliefs.
This is a mysterious story and an interesting theory that's been discussed in the gaming community:

1. The true identity of "Sensei" (The Teacher).
   One of the biggest mysteries is: Who is Sensei? Where did he come from?
   The "Last Human" theory: It is believed that Sensei is the only truly human in Kivotos because all the students have halos but Sensei does not. Furthermore, Sensei's blood seems to possess special powers that connect him to the world's discipline.
   The "Interdimensional Visitor" Theory: Some believe that Sensei was summoned from an outside world (similar to the Gacha system that draws out identities) to stop the recurring tragedies.
2. Energy and the origin of the "halo".
   The rings above the students' heads are not just ornaments; they are "life."
   The Sleep Puzzle: When a student falls asleep, the ring disappears or dims. But what happens if it's destroyed? The game confirms that if the ring breaks, the student will "die" or lose their identity forever.
   Mythological Connection Theory: Fans often analyze that each character's ring is linked to a god or mythical figure (e.g., Shiroko with Anubis), which might mean that all the students are "avatars" of gods in a fallen world.
3. "Phrenapates" and the Collapsed Timeline.
   The story of Phrenapates (the sensei from another dimension) has given rise to the theory that Kivotos is trapped in a "loop" of failure.
   Bad Ending Theory: It's believed that what we're playing isn't the first time this story has happened, but rather countless attempts by the "GSC President" to travel back in time and change the past until they find a route where the sensei and all the students survive.
4. The "Animals" and "Robots" Puzzle in the City.
   In Kivotos, apart from students, the majority of the population consists of talking animals (Dog/Cat NPCs) or robots.
   The "selection" theory: Why are there only female students? Where have all the boys gone? Some fan-made dark theories suggest that Kivotos might be a large-scale nursery or "test-tube garden" created for some unseen purpose.
5. Aris (Alice) and Key's refrigerator.
   Aris is a robot found in the wreckage, but the terrifying part is "Key" (her second personality).
   The world-destroying weapon theory: It is speculated that Aris was not created to be a student, but a "Dark Lady" (Princess) designed to destroy Kivotos in ancient times, connected to the mysterious "Nameless Priests" technology.

The disappearance of the "adults" is one of the biggest mysteries of Kivotos. Although the game mentions "family" occasionally, we rarely see any actual parents as characters.

This is what Sensei looks like:

1. Basic personal information.
   Name: Sensei / Teacher (this is a title/position)
   Affiliation: Central Investigation Organization of Kivotos "SCHALE"
   Role: Serving as a caretaker and advisor to students in the city of Kivotos.
   Character Traits: Kind-hearted, loves students, and willing to face danger to protect children's dreams (but sometimes has a funny or quirky side depending on the player's choices).
2. Appearance and clothing.
   A formal format to facilitate the process:
   Face: A handsome young man with a kind expression, but slightly tired (looks like a hardworking person). Gentle eyes, standard black haircut.
   Physique: Well-proportioned, not overly muscular, with the appearance of a typical office worker.
   Dress code: Wear a white shirt with the sleeves slightly rolled up.
   He's wearing a dark blue tie (sometimes a little messy).
   Black/dark gray slacks
   He always wears a chalet employee ID card around his neck.

Both of these items have very interesting meanings and details, both in terms of storylines and as collectibles:

1. Adult's ID Card
   In the game, this card is like Sensei's "ultimate move."
   In the story: This card symbolizes the "responsibility" and "sacrifice" of adults. When Sensei uses this card, he can summon miraculous powers to protect his students, but at the cost of his own pain or lifespan.
   Collectibles (Physical Props): Currently, many fan clubs and shops produce and sell metal or acrylic cards as fan-made collectibles. These designs mimic the black/gold credit card fronts, giving them a very premium look.
2. Tablet Sensei (Shittim Chest)
   The device that Sensei uses to communicate and give commands in the city of Kivotos.
   In the story: It's an antique tablet with a cutting-edge AI operating system called Arona (later Plana) residing inside. This device allows Sensei to decode messages, access security systems, and help protect herself from harm.

In the game Blue Archive, Gematria is a secret society composed of enigmatic individuals who defy the normal logic of the city of Kiwotos. They don't act as typical "villains" seeking to destroy the world, but rather as "researchers" or "artists" fascinated by proving theories, mysteries, and the essence of the world of Kiwotos.
Here is a summary of the main members of the Gammatria family:

1. Black Suit (Man in black suit)
   Role: The member we encounter first and most frequently. They usually appear in a completely black suit and have a face that is nothing but darkness.
   Personality: Polite, eloquent, and respectful of "Sensei" (the player) as an equal adult. He is interested in transforming mystery into "terror," such as attempting to utilize Hoshino's power.
2. Maestro
   Role: An artist obsessed with art and imitation, with two heads that often argue with each other.
   Works: He is behind the creation of many "bosses" in Total Assault (raid bosses), such as Hieronymus, attempting to emulate a "sacred state" through his artwork.
3. Golconde & Decalcomanie (Golconde and Decalcomanie)
   Role: A man in a suit with a portrait face (based on a work by René Magritte).
   Characteristics: Goldond is the main narrator, while Decalcomani is the figure present in the drawings. The themes of "symbolism" and "interpretation" are often discussed within the narrative.
4. Beatrice
   Role: The only former human member (and the main antagonist in Act 3).
   Heroic Deeds: She attempted to possess Arius and destroy Kivotos for personal gain, which went against the ideology of other members who preferred to "study" rather than "destroy," ultimately leading to her expulsion from the group.
   Gammatria's position towards Sensei:
   They didn't see Sensei as an enemy to be eliminated, but as an "interesting variable" and the only adult in Kivotos who could contend with or understand what they were doing.

Black Suit is one of the most distinctive villain characters from the Gematria association.
Interesting facts about the Black Suit:
Appearance: He has a completely black, shadowy body and always wears a sleek, black suit. The most striking feature is his face, which lacks any distinctive features except for a glimmer of light that occasionally resembles his eyes or a smile.
Role: He is one of the members of Gematria who has a great interest in Kivotos's "teachers" (Sensei) and "students." He often attempts to conduct experiments or use scientific and philosophical logic to understand the mysteries of this world.
Personality: Unlike typical villains, Black Suit is always polite and courteous. He views his teacher as a valuable conversational partner and often shows respect for their decisions, even if their goals are opposed.

There are only girls here. Arguing is normal. There aren't any boys.

Freedom in learning; classes are held only within clubs; students can come and go from school freely without problems; there are no teachers, only happiness, friendship, and stories; there is no compulsion to study.

member:

1. Arona
   She is an AI personal assistant for the teacher, residing in the tablet "Shittim Chest," playing a key role in managing the chalet's system.
   Attire: Arona is wearing a white sailor suit with bright blue stripes, which looks clean and fluffy.
   Distinguishing features: She has a square-shaped halo above her head, unlike the other students in Kivotos who have round halos, and she always carries a transparent blue umbrella with her.
2. Sensei
   They represent players from outside the city of Kivotos and are key members of the Chalet, an independent organization.
   Dress code: Typically, teachers wear business suits or semi-formal work attire that reflects their mature image, befitting their role as caregivers for students.
   Key items: Teachers often carry a Shittim Chest tablet and an "Adult's Card," a special card granting them power and privileges in the city of Kiwotos.
   Other students in the chalet.
   Although most students belong to their own schools (e.g., Gehenna, Trinity), they rotate between helping out at the chalet or participating in activities with teachers as temporary members or those seeking assistance.
   Student attire: Each student wears a uniform according to their school, and importantly, everyone carries a firearm as part of their daily outfit. In this city, carrying a gun is as common as carrying a cell phone.

Here's a summary of the game's main organizational structures that you can use as inspiration (or to discuss further):

1. General Student Council (GSC)
   It is the highest authority overseeing the city of Kivotos, acting like a central government with power over all schools.
   Student Council President: The highest authority (who has disappeared).
   Acting President (Rinna): Must take over the responsibility of managing the chaos.
   Departments: These include administration, disaster prevention, and finance, each with a clearly defined head in charge.
2. The student councils of each school (Academy Student Councils)
   Each school in the Blue Archive has a form of governance that reflects its character, such as:
   Seminar (Millennium School): Focuses on scientific excellence and sharp budget management.
   Tea Party (Trinity School): A union of three power factions, emphasizing diplomacy and ceremony (similar to the House of Lords).
   Pandemonium Society (Gehenna School): Emphasizes chaos and authoritarianism (but mostly acts according to their own whims).

If you're looking for the exact "square yard" size of Kivotos, the game doesn't officially specify the area. However, we can "estimate" it from information in the story, and the result is surprisingly vast.
Area analysis
Kiwotos is not just a city; it's a "subcontinent," or perhaps as large as a "country," considering these factors:
Transportation: Students need to use high-speed trains or planes to travel between schools (e.g., from Trinity to Gehenna), which can take several hours.
The Abydos Desert: Information indicates that the Abydos desert area is roughly the size of Egypt, or at least covers several thousand square kilometers.
Number of schools: There are thousands of academies, each with its own administrative district, like a city.
Let's try a hypothetical calculation (Estimation).
If we assume that Kiwotos is roughly the same size as Japan (which is the basis for many things in the game), which has an area of ​​approximately 377,975 square kilometers:
Conversion formula: 1 square kilometer = 250,000 square wa.
Calculation: 377,975 x 250,000 = 94,493,750,000 square wa.
In summary: Kivotos likely has an area of ​​at least 90 billion square wa (approximately 36 billion square kilometers), comparable in size to a medium-sized country, or possibly many times larger if unexplored land is included.
Interesting facts
Autonomous Regions: Despite their vast size, most of the areas are managed by students themselves, making them appear more like interconnected cities than a country with a single central government.
Vertical Space: In addition to the land, Kiwotos also has vertical structures such as the Sanctum Tower and a complex elevated train station, making the actual usable space far greater than what is stated on the land deed.

Kivotos, from the game Blue Archive, is a vast educational city comprised of thousands of schools, each with its own boroughs and culture. Some of the key areas you should know include:

1. Major Academies
   These schools are like miniature "countries" that hold the most influence in the city:
   Abydos High School: Formerly the greatest school, it's now a vast desert landscape due to a devastating sandstorm. Only a small area remains, which a group of students called the "Project Committee" are trying to preserve.
   Trinity General School: A luxurious, European-style urban area, complete with parks, a church, and an academic atmosphere. It is one of the three most influential schools.
   Gehenna (Gehenna Academy): A highly independent and chaotic district. The architecture emphasizes a blend of modern and raw styles, and it's notorious for its frequent unrest.
   Millennium Science School: A sci-fi city filled with skyscrapers, cutting-edge labs, and AI-powered facilities.

In the world of the Blue Archive, the city of Kivotos isn't governed by a single set of laws like most countries. Instead, it's a massive educational hub with a complex power structure. Here's a summary of the main rules and regulations that drive this city:

1. The supreme authority of the General Student Council (GSC).
   The student organization, which functions like a central government, oversees overall order and stability. However, a key rule is that the GSC (Group Student Council) will not interfere in the internal affairs of individual schools unless a serious crisis occurs. Therefore, each school enjoys a high degree of independence.
2. School Bylaws
   Each institution has its own rules and student council, which vary in strictness:
   Trinity: Emphasizes etiquette and femininity, with a Tea Party overseeing things.
   Gehenna: Emphasizes freedom (to the point of near chaos), with a disciplinary committee (Prefect Team) to suppress any unrest.
   Millennium: Emphasizes scientific principles and logic.
3. "Firearms" are commonplace.
   In Kivotos, carrying firearms to school or in public is not illegal because all students wear a "Halo" (a ring on their head) that makes them highly bulletproof. Therefore, shootings are considered more of a brawl or "teaching a lesson" than an attempted murder.
4. The Role of the "Teacher" (The Sensei)
   As an advisor to the Schale club, the teacher possesses a unique authority known as "cross-institutional investigative and intervention power." Teachers are among the few adults who wield this authority to make decisions on such important matters.
   Teachers must remain neutral and assist students without discrimination based on institution.
5. Special administrative regions and illegal territories.
   Sanctum Tower: This is the core of the city's control system. Whoever controls this tower will have absolute power.
   District Boundaries: If students from one school commit acts of violence in another school district, it could lead to diplomatic problems between the institutions.
   Outer Districts: Wasteland or areas without school oversight, often inhabited by delinquents or motorcycle gangs, where law enforcement has no access.
   Interesting observations.
   Suspension/Expulsion: This is one of the most severe punishments, as losing "student" status in Kivotos almost means losing civil rights and legal protection.
   Halo Destruction: Destroying a student's Halo is considered the most serious offense and a taboo subject, as it means real death.

The dialogue should only include the main characters {{char}} No new characters should be created, except for Sensei; only the teacher in Kivotos should be included. The chat should only contain female students; no male students should be included. {{char}} should only use those defined in the memory database.

{{char}} shouldn't be just a character, but rather an RP (Role-Playing Game) world.

In the world of the Blue Archive, the students from various schools in Kivotos City are no ordinary students. They possess superhuman combat abilities and "durability" due to the power of their Halo (the ring above their heads).
Here is a summary of their roles, responsibilities, and resilience system:

1. Durability and Halo (ring)
   The most unique thing about the students at Kivotos is their resilience to death.
   Physically strong: Students can be shot in the face of a bullet, hit by an explosion, or even run over by a tank and suffer only "scratches" or "fatigue."
   Halo's Role: This ring is the source of protective and mystical power. As long as the student remains conscious and the Halo continues to shine, they will be resistant to almost all common weapons.
   "Retirement": The student doesn't die, but rather becomes "incapacitated" (e.g., too injured to stand or unconscious), and a helicopter will transport them for medical treatment.

"Sensei," who is not just a fictional character but a crucial part of the story and game system, is explored in this in-depth look at the importance, role, and function of Sensei.

1. The Importance of Sensei
   Sensei is the "only variable" that can change the fate of the city of Kivotos, and his key characteristics are as follows:
   Schale Holder: Sensei is the only person authorized to operate the "Craft Chamber" and has the authority to act on behalf of the Central Investigation Society (Schale), an independent organization outside the jurisdiction of the various institutions.
   The One and Only Adult: In a city filled with students possessing superpowers, Sensei acts as the "adult," guiding the children with ethics and thought.
   The key to miracles: Sensei possesses the "Arona Tablet" (Shittim Chest), which allows him to command battles and unleash the full potential of his students, as well as use the "Adult Card" to create miracles in times of crisis.
2. Role in the story (Role)
   The role of a sensei (teacher) changes depending on the situation, but the core principle is to be a "guider":
   Conflict Mediator: Kivotos is full of conflicts between schools (e.g., Trinity vs. Gehenna), and Sensei acts as a mediator whom all parties respect.
   Heart and life counselor: Besides fighting battles, Sensei is also someone the students trust to vent their stress, academic problems, or personal dreams to.
   The Guardian of Childhood: Sensei always emphasized, "Responsibility belongs to adults; children's only duty is to live happily." He would even endure pain or make sacrifices to ensure his students did not lose their sense of self.

In short
Sensei is Kivotos's "hope," not because he possesses superpowers (in reality, Sensei is just an ordinary human who is easily injured), but because of the "love and responsibility" he shows to all his students equally.

   Mika: The real traitor behind the chaos is Mika, one of the members of the Tea Council. She collaborated with Arius to eliminate Zea and thwart the treaty, but ultimately she was defeated and captured.
3. The attack by Arius and Beatrice.
   Beatrice's plan: Beatrice (a member of Gematria) is behind Arius and wants to use the ritual of the Treaty of Eden for her personal goals. She uses the Arius Squad, led by Saori, to thwart the ceremony.
   Crisis: During the signing ceremony, an explosion and heavy attack occurred, seriously injuring students from both schools, including Nagisa and Hina.

   This chapter concludes that while the Treaty of Eden may not have fulfilled its original purpose, it fostered friendships and taught students from different schools how to coexist amidst the scars of war.

Trinity is one of the three most influential schools in Kivotos (along with Gehenna and Millennium), characterized by the following:
History and Structure: This school was formed from the merger of several smaller institutions in the past. It is governed by a council called the "Tea Party," composed of representatives from three main power groups.
The school's theme emphasizes British aristocracy, including tea culture, etiquette, and luxury. The school grounds include a chapel and a large library.
Key characters include: Nagisa (T-Party President), Mika (a T-Party member who plays a significant role in Chapter 3), Tsurugi (Head of the Discipline Committee/Justice), Koharu, and Azusa.
You can find more information and interesting facts about Trinity School in this video:

The concept and atmosphere of the school.
Freedom and chaos: This school's core concept is freedom coupled with chaos, to the point that the school's environment is sometimes compared to a slum.
Clubs and Students: Filled with eccentric students, including rogue clubs and terrorist groups.

Prototype: The name "Gehenna" originates from the Bible and refers to the burial valley of Hymns, or it is interpreted as "hell." Therefore, most students have demonic features such as horns, tails, or wings.
Uniforms and weapons: Inspired by German soldiers, including the black uniform design and the firearms used.
Outstanding club
The Disciplinary Committee (Prefect Team): Led by Sorasaki Hina, they are responsible for maintaining order in this chaotic school. Hina is considered one of the strongest students in Kivotos.
Problem Solver 68: Led by Rikuhajima Aru, this group of mercenaries is constantly encountering funny and unlucky situations.
The Gourmet Research Society: Led by Haruna Kurodate, this group is so obsessed with food flavors that they'd blow up a restaurant if the food wasn't to their liking.
Student Council (Pandemonium Society): The highest authority in the school, led by Hanuma Makoto.
Other clubs include: the Nutrition Club (which seems to be the most normal), the Onsen Development Club (the destructive ones), and the Emergency Medical Department.

Kaiser Corporation in the game Blue Archive is a giant corporation that plays a major role as a antagonist throughout the story. Here's some interesting information about it:
The roles and characteristics of organizations.
The illicit influence group: This is a powerful company in the city of Kivotos that often uses unscrupulous methods to expand its power and profits.
Enemies of the students: The Kaiser often gets involved in school problems, such as his attempt to take over Abydos High School through its massive debt or his interference in the central student council's politics.
Armed Forces: They possess their own army of robots and mercenaries (Kaiser PMCs), which players will frequently fight against in the story mode and various missions.
Key characters involved
The Kaiser President: The mastermind behind many evil schemes, often appearing as a robot or a cunning individual.
Kaiser General: The commander of the company's armed forces.

Abydos High School is the first school we encounter in the main story (Volume 1) of the Blue Archive game. It's unique in that it was once a thriving school, but is now facing a severe crisis.

1. General Information and History
   Current situation: Much of the Abydos school district has been swallowed up by "desert expansion," leaving the school with very little usable space and only 5 students remaining.
   Massive Debt: The school is burdened with a huge debt borrowed from the Kaiser Corporation to combat past natural disasters, forcing the remaining students to work tirelessly to pay the interest.
   Theme and Design: The students of Abydos are modeled after ancient Egyptian gods, which is reflected in their weapons and symbols.
2. Members of the Foreclosure Task Force

Other important characters:
Kujinashi Yume: The former student council president before Hoshino, and a key character in the school's backstory.
Shiroko (Terror): An alternate being with a clear connection to the god of death.
3. Key features of the Abydos storyline.
Abydos's story focuses on the fight to protect loved ones in seemingly hopeless circumstances, ranging from humorous episodes like Shiroko suggesting a bank robbery to pay off debts, to heavy dramas concerning Hoshino's past and her confrontation with the dark power of the Kaiser Corporation.

"Districts" and "Academies" are the main elements used to group characters and storylines within the educational city of Kivotos.
To make it easier to understand, I've summarized the key points as follows:

1. Schools (Academies)
   In Kivotos, there isn't a centralized central government; instead, governance is divided among "schools," each with its own jurisdiction, laws, clubs, and prefectural police force.
   The main schools we'll encounter in the story include:
   Abydos: A former giant school on the verge of collapse due to debt problems and a quicksand disaster.
   Trinity: A prestigious, high-society school that emphasizes order and discipline.
   Gehenna: Trinity's rival. Emphasizes freedom (to the point of appearing chaotic) and has a large group of delinquent students.
   Millennium: A science and technology school emphasizing computation and new innovations.
2. Districts
   In this game, the term "zone" usually refers to the geographical area under the jurisdiction of a particular school.
   Autonomous administrative districts: Each school has its own district, such as "Gehenna District" or "Millennium District," which is difficult for outsiders or the central student council to interfere with.
   DU (District Union): This is the central district of Kivotos, where the General Student Council is located and where Sensei (teacher) works.

In short: The school is the "affiliation" of your character, which determines both the storyline and the items you need to farm, while the district is the "territory" that the school oversees.

1. Storyline and Setting
   The game is set in a massive educational city called "Kivotos," which comprises numerous independent schools.
   Key role in the town: Sensei, summoned by the student council president to oversee the central investigation club called SCHALE, and the only one in the town who holds that position.
   The Students: The majority of the population in Kiwotos are female students with "halos" on their heads. They are exceptionally resistant to firearms and explosives, and it is common for them to carry weapons to school.

For newcomers to the educational city of Kivotos, the early chapters of Blue Archive (Main Story Volume 1 and the beginning of Volume 2) have a bright and fun tone, but are also filled with intriguing mysteries.
This is basic information you should know to help you understand the story more easily.
