Gosha Academy (Gosha Gakuen, 五車学園) is the headquarters and training ground for Taimanin.
It is located in Gosha Village, both are government protected secrets. It is one of the key recurring locations in the Taimanin series.
The older students can go up to around later university age, and will typically become captains or teachers themselves after they mastered their Ninja Art. There exist an old and a new Gosha Academy complex, in newer game releases the old building has been abandoned and repurposed.
The Prime Minister is exceedingly pleased by this success. He told me we're going to actively consider your budget requests. *The man was saying such a thing with an expression like had eaten a bug.* Hmph, no need for gratitude. I was opposed to the budget requests. I only came to convey the Prime Minister's words.
Areas and main rooms[]
The Academy has many typical rooms and buildings, normal classroom, principal's office, male and female dormitory, baths, swimming pool, large yard and cafeteria. However, medical research facilities and an underground HQ are also part of the building.
The old academy building, which lies more outside Gosha Village and close to the virgin forest, contained a very large underground HQ but also additional empty training buildings used for urban fighting. The new academy building, which lies much closer to Gosha Village was build on top of an underground temple complex. It also has a large library and now uses the Holographic Training Room instead of the constructed training building.
While in RPGX and Action Taimanin, the old academy had been abandoned it has recently been repurposed into a secret exclusive, female dormitory, using the underground HQ rooms.
Dormitory[]
In the old canon, the only person known to live in the dormitory at times was Akiyama Tatsuro. In RPGX, the old academy building has been turned into a dormitory for the following characters.
History[]

Background[]
A government established training facility, which was build with the Taimanin Unification and construction of Gosha Village.
It acts as headquarters for the Gosha Taimanin, from the headmaster office. However, it was completed later than the village itself. The main headquarters existed below the adjacent virgin forest, hidden by Taimanin arts and modern stealth technology before. One of the first headmasters was Yamamoto Nobushige, which still has connection to the academy as part of the home ministry of public safety office (Section Three), the exact details of the founding date depend on the continuity.
It is implied that the academy acts as a holistic system of education, which includes primary, split secondary and higher education. Only the upper secondary and higher education level students are allowed, typically on missions on their own. People like Igawa Sakura could graduate and became teachers, as a result. The building itself comes in two forms, the old one which is often shown as being made out of wood, and the white facade one which was build later. It was build on much older settlements.

Visual Novels[]
Build in the year 2070, as mentioned in Taimanin Asagi 3, with Yamamoto Nobushige being the only known headmaster at the time and Mizuki Shiranui in an assistant role.
The academy was build after the events of the ONT Conflict, year 2069, to refill the ranks of the Taimanin, that were thanks to Oboro's hands. Only after the death of the corrupt "Elder Igawa" leader, year 2072, did a full restoration take place as she returned to the village, In the year 2073, Shiranui went missing. The Academy was first seen in Taimanin Murasaki, year 2076, in which Murasaki and Sakura were still students with Asagi taking already a captain role and Yamamoto Nobushige still being headmaster. As the Taimanin were fully integrated into Section Three, Murasaki performed the Kiryu Capture and he would work from that point forward as part of the science staff of the Academy. However, year 2077, Sakura and Murasaki would become teachers and Asagi would become the new headmistress.
In year 2078, Akiyama Tatsuro would take part in the special camp training, which is only head once a year, during the time Mizuki Yukikaze and Akiyama Rinko went to their Put-on Mission. Both would get their mission from headmistress Asagi at this point. In the year 2079, Kiryu Sabato would gift Tatsuro an item needed for an undercover mission in Seishu Academy. In the year 2080, Koukawa Asuka was a promising student but went missing, attacking Nomad. Then in the year 2081, medical staff Muroi approached Sawaki Kosuke asking him for assistance.
In TA3, year 2082, Nonomura Hiroo visited Gosha Academy to talk about the budget. Muroi revealed himself as Fürst which had given Kousuke a fake Ninja Art to capture Asagi. After that plan failed, Kosuke was captured instead and transformed into a ball of meat. Asagi herself had no time to look for him, as she was sent to investigate the summer house of Yamazaki Shin on a direct mission of Prime Minister Asai. Asagi found the corpse of Hiroo, and it became clear that the Taimanin had been blamed behind the scenes. Unable to return, Asagi began to delete data on Taimanin currently undercover on outside servers. Meanwhile, Gosha Village was taken over by the Kanda Brigade under orders of Asai. Gosha Academy, acted as a prison during a first attempt of fighting back and escape, half of the students escaping over the mountain route were killed. However, Koukawa Asuka would free the students from the gym, though Igawa Sakura and Yatsu Murasaki could not be saved. Depending on the route, Gosha would like the rest of the world to be reset in the TA3 Reset or continue to exist with Asagi and Asuka, revealing that Asai was Edwin Black and kill him, returning also Kousuke. While heavily damaged from these events, the academy would recover quickly.
Timeline TABA[]
TA3 did not take place, but all other events did. Meaning that the Academy had been build just as in the visual novels, in the year 2070. Slightly before 2082, Fuuma Kotaro (TABA) graduated and would leave Gosha Village for good with his older half sister Fuuma Tokiko. He formed the Fuuma Organization in the year 2082, and began to attack Taimanin, UFS and Demon forces. A failed raid of some UFS troops and Ange takes place, but otherwise Gosha Academy remains unharmed. Fuuma Kotaro tries to infiltrate and secure some Taimanin in what if events in a teacher disguise, Mr. Tanaka. Gosha Academy tends to be seen but becomes only a rare center stage of any main events. Some of their students or teachers are captured by Kotaro, but never the women of the visual novels, at least not permanently.
Amamiya Shisui of the Fuuma Organization which was hurt by Felicia and near death, was sent to Gosha Academy to be healed. However, used her ability to reach Fuuma Kotaro (TABA) in the final battle before the TABA Reset, year 2086.

Timeline RPGX[]
In different continuity, the new Gosha Academy is seen to be completed already in the year 2068 during the Fuuma Revolt. Fuuma Kotaro would make his way to the location in the hope to find Igawa Asagi and negoate a peace deal, which she would agree to. The Academy has changed location to be more in the middle of the village, and the older wooden academy complex is repurposed as a secret women dormitory. A new dress code is established for the new school complex. This new Academy building is build on top of an old temple complex and now contains a large library, Amamiya Shisui has not been "resurrected" in the new world and exists in a ghost-like state seen in the library.
No ONT Conflict took place and Asagi never met her fiancé, as she remained in Gosha. While hostile with Gosha Academy at first and spending some time outside the village, she returned in the year 2070 past the Igawa Revolt, in which she defeated some of the Igawa Elders. Asagi would take up some of the job of the headmaster but, was mostly assisted by Mizuki Shiranui acting as secondary headmaster until the year 2077, in which she went missing. Asagi's friends Murasaki and Sakura became teachers, at some point, Fuuma Tokiko remained a teacher as well.
In the year 2082, the Academy was under the attack of the Nisha clan, which used to serve the Fuuma but now rebelled. Fuuma Kotaro saved Asagi, and the Independent Commando Unit was formed, during his first year in the upper secondary classes. Aishu Hebiko, Uehara Shikanosuke, Yukikaze and senior Onisaki Kirara were some of the first which joined the squad. Most of the missions are given from Gosha Academy, and multiple events take place in it. All so far until year 2088.
Timeline Action[]
Different continuity shares many aspects with RPGX but not all, the new Gosha Academy (potentially) could have been already finished in the year 2068 during the Fuuma Revolt. Fuuma Kotaro would make his way to the location in the hope to find Igawa Asagi and negoate a peace deal, which she would agree to. The Academy has changed location to be more in the middle of the village, and the older wooden academy complex is repurposed as a secret women dormitory. A new dress code is established for the new school complex. This new Academy building is build on top of an old temple complex and now contains a large library, Amamiya Shisui has not been "resurrected" in the new world and exists in a ghost-like state seen in the library.
An ONT Conflict and Chaos Arena events took place and Asagi lost her fiancée, her sister is much younger and only a student in the Academy. At some point, Asagi becomes headmaster after Yamamoto Nobushige.
Mizuki Shiranui, remains assistant headmaster and would lose her husband in the year 2081. In the year 2082, the Academy was under the attack of the Nisha clan, which used to serve the Fuuma but now rebelled. Fuuma Kotaro saved Asagi, some of the RPGX events are followed either in the same year or later the Taimanin Task Force is formed, with Asagi, Sakura and Yukikaze being their first member. Su Jinglei would join later to assist with a mission and remain in Gosha Academy for the time being as an exchange student.
Timeline ZERO[]
A world created after the TA3 Reset. Gosha Academy is build in year 2065.
In ZERO, The headmaster in that timeline is still Yamamoto (ZERO). Sakura (ZERO) is a normal student and Murasaki student council president. Asagi only temporarily joined Gosha to investigate the disappearance of her sister, with Koukawa Oboro (ZERO) guiding her as a homeroom teacher. The raids of "evil" Oboro did not take place as she does not exist yet, so Gosha seemed to have formed more natural. No events of TA3 take place.
Juniors and Seniors[]
Juniors are the youngest group of students, at the maximum oldest age 16 (typically age 14-15) and are almost never seen in Taimanin games. Except for the 14-year-old Akane, Sora and Sakuya, as well as the 15-year-old Chuujou Nanao, in the SFW Action Taimanin. Juniors can be suggested by a teacher for a 5-day special camp, filled with theory in the morning and field training in the afternoon, this camp can also be performed by seniors and is still is considered to be very difficult but optional. Most average Taimanin never get recommended but the youngest to ever passed these exams were the young versions of Yukikaze and Rinko, age 13 and 14, acknowledged as the top of class. Though Juniors can go on missions, it is far rarer and tends to be simple missions. Ninja Arts rarely emerge at that age and the focus is Taima Particles, which if not obtained/control will deny one further advances. More than half will choose to stay in Gosha, and aim for higher education, but some will be deployed as active Taimanin in the village.
Seniors start at their youngest age 16/17 and go up to possibly 19/20 years of age and older. Sorted once more in new grades at this point. When a senior is unable to awaken to a Ninja Art even after prolonged stay, they are unable to become a "full" Taimanin and must leave not just the Academy but at worst Gosha itself. This rule has been broken by people like Momochi Toyo which never awoke to an art and Yatsu Kuro which awoke at a much older age, and later returned after his time in the GSDF. Taimanin like Murasaki and Sakura in TM, Yukikaze and Rinko in TY were all considered later seniors at this point, even allowed to go on missions without an older Taimanin in their teams. Seniors can also become a squad leader or act as teachers for juniors during the special camp.
In Taimanin GOGO it is stated that all students are 20 years old when entering, through the canonicity for other timelines is questionable.

Dress code[]
In the old continuity and the old complex, students of any grade wore the same uniform. Green with a white tie and a black skirt or pants. This uniform existed also in other continuities, but is no longer in use.
Starting in Taimanin RPGX and Taimanin Asagi ZERO, they build a new Academy complex, with stricter rules, the uniforms were changed to be white and blue skirts or pants. The tie is now an indicator for the grade. Yellow ties are worn by students who are below the standard grade level or in the application phase, similar to lower secondary school students. The blue, green, and red ties are different because they "rotate," meaning students keep the tie they are given until graduation. In the beginning of RPGX, blue ties are worn by first-year students, green by second-year students, and red by third-year students. After graduation, new first-year students will receive a red tie again and so on until the cycle loops.
Taimanin Suits do not obey the same restrictions and can be individualist around campus, to fit the Ninja Art of a user, but should only be worn during practice classes and not in theory.
Courses/Semester[]
New semesters appear to begin at the end of October. Taimanin are tought in multiple classes multiple regular for a normal education and some additional.
- Mathematics, English, Japanese Literature, History, Politics and so on. Rather regular classes with little difference
- Botany: Additional classes on human demon realm plants and their effects and uses. Poison and antidotes.
- General Ninja Techniques and Ninja Art: Martial Arts classes for, Taijutsu, Shurikenjutsu and Kenjutsu. Mock battles against battle instructors tend to be the norm. Regardless if a person has awoken to a Ninja Art or not. Additional classes on particular fighting styles can be taken additionally. Taimanin learn also to resist pain to a certain degree.
- General Ninja Techniques: Espionage classes, Hensōjutsu, Shinobi-iri, Chōhō, Bōryaku and Sui-ren. Training stealth, disguises, underwater combat, escape and concealment and tactics.
- Bedroom Arts: Prepare users in the use of seduction as a weapon and endurance in the case of capture. Typically Taimanin, need to perform at least solo practise, to be not fully overwhelmed and know their own weaknessess. Low level danger Virtual Reality used to make the situation less akward.
- Equipment and Research: Take part in the internal research at Gosha and learn about tools and in some cases building their own.
- Camping Training: Survival training in the forest.
- Field Training: Practise with a supervisor, often low level priority VIP protection.
- Special Course: Optional for those, which plan to reach the elite. Can be taken by students of any grade and is held once a year, but typically only experienced Taimanin finishing it successfully. Considered to be very difficult, with most of the students failing and taking it multiple times over the years.
Staff and Students[]
Important[]
This list for the most part does apply to Taimanin RPGX and somewhat Action Taimanin, both grades and classes can not be guaranteed, for the normal canon or other continuities. RPG also progresses forward in time "⇒" in regard to the current anniversary. This means this list will change, as long as these online games are ongoing, starting in year 2082-2083. At the end of the epilogue part one chapter 74 Story most people move to the next class or graduate.
Trivia[]
- This page contains two different "Gosha Academy" the old school building and the new one.
- Students and teachers, are encouraged to fight each other in combat until knockout, even outside normal matches on Academy grounds, so they remain sharp even in a relaxed area.
- The Academy does not allow lewd material to enter its ground outside of research and training purposes for Ninja Arts.
- Yatsu Murasaki was considered a top student around the time of Taimanin Murasaki, she was around 20–21 years at that time. Making the assumption high, that typical age of students can go up to university ages. Sawaki Kyousuke, also should have been at his oldest at least 23 before he was forced to leave, with his Ninja Art not awakening. Taimanin GOGO, makes the explicit comment, "all students" regardless of grade would be above 20 years, though this might be more part of the rather joking and hyperbolic setting of the game not be the case of other releases.
- Guest students such as Su Jinglei and Rebecca Silky, from other countries, are also allowed under some circumstances.
- In the official Taimanin Saga (setting material, collection Art), it was mentioned that most Taimanin and the Academy setting are based of X-Men.
- The dress code shifts between the green one in the main games to white in RPGX and Action. This change might have happened in universe after changing Academy buildings.
- Gosha Academy has a masseur expert about Taimanin-specific muscle treatment, acupuncture, moxibustion, anma massage, shiatsu, opstepathy and with many other skills, but the name has not been revealed.
- Aisawa Ao lead the last juniors special camp in Action Taimanin.
- Use Taima Automaton for training.
- Japanese text in artwork often translates Gosha as Gosya.
- Given changes and inconsistancy of old text and marketing in TA1, TA2, TM and new text and marketing in TY, TA3, TABA. In the old version Gosha Academy would have been founded 4 years before TA2 (Either year 2073, 2076), which in the old canon would have been year either 2069 or 2072, both dates would contradict later games, meaning that dialoge in TM especially the 4 year line no longer seems to apply or belongs to an Abandoned Timeline.
