The JHWAB was created at the start of the Meiji Government, the Shogunate had left the Hidden World without any supervision and it was starting to become dangerous, so taking in account the advice of the British allies to the government, an office originally called “Densetsu-sho” (Ministry of Legends) it was handled very differently as its current form. The original mission of the office was the eradication of the Hidden World in Japan, under the mistaken impression that the western advance was a sub product of cutting ties with the mythic past and locking their views to the future. Without mistake this was a very bad idea, as the Hidden World denizens, threaten towards extinction decided to join forces. The stupidity of the Densetsu-Cho officers managed to break conflicts in the non-human community and allowed them to, for first time in ages, join forces.
This was the first occult war of modern Japan, descending from the north a massive army of Yokai started attacking the outposts of the Office around the Islands. The current Densetsu no Daijin (Minister of Legends) forced a recruitment drive among the families that practices Hidden Arts, to counter the incoming horde. Begrudgingly, the Omnyo, Ki and Exorcism masters joined forced against those who surely were related to them by blood, trade or just shared traits. The war lasted 1 year ending on the dawn of the 20 Century. Both sides received a heavy blow and retreated to lick their wounds. The Minister resigned and was replaced by a powerful and respected Omnyo Master Senmei Yasunori, who started reconnecting the relations between humans and Yokai, trying to avoid another war, he was somewhat successful and 8 Half-Blood clans were formed.
Two decades of peace helped a lot to heal the estranged relations between both sides, but when the Taisho Democracy fell and the militarization of the country started, the new government demanded the Office to provide the army with Yokai. This was an infringement of the silent agreement of the countries to keep the nature of the Hidden World apart from the attention of the general public. Senmei Yasumori opposed to this demands, but at the start of the Showa era his oldest son, Haigo Yasumori poisoned him and killed him in a duel with the help of the rest of his siblings except for the youngest Roshi Yasumori. Haigo, drunk with power, changed the name of the Office to Sengoku Densetsu-Cho (usually abbreviated to Senden-cho) and started preparing. His younger brother, the only who didn’t betray the family name and convictions started an underground resistance against his brother forces, skillfully managing to stop the corrupted ministry to enact the new government demands.
This secret war continued, with more and more people defecting to join Roshi. Haigo, filled with despair made a deal with the devil and joined forces with the German investigators, capturing Yokai or even minor deities and using them in cruel experiments on the secret Ryugu-jo complex. This continued until the country surrendered, with the fall of the government Haigo lost his edge and Roshi took advantage of it, finally toppling down his brother and ending the “Yasumori Sengoku” conflict. The New Government offered Roshi the control of the Minstry, but he asked to change some aspects of it. He funded the current incarnation of it, the “Nihon no Kakushi Sekai Minikyoku” or as we know it the JHWAB. He installed a very organized system that would not only serve as protectors but as a bridge between worlds. Roshi’s goal is to make both sides co-exists peacefully. With that in mind, he decided to start from where that was already accomplished, thus he decided to keep the most important positions open for members of the 8 Taisho Clans, the 8 Half-Blooded families born from the efforts of his father.
Still the Half Yokai wouldn’t be enough for what the world had prepared for the Bureau. Another 20 years of somewhat peaceful days started in 1950, but when the 7 decade of the Century was at dawn a new danger. A mad scientist/alchemist that went by the name of Eiyu Shomei opened a portal to a strange dimension populated by a race of beings, which in theory, were created by the condensation of humanity’s thoughts, imaginations and feelings. According to further research, these beings, called Gainen are a sub product of human psyche, under the law of energy conservation (Energy cannot be destroyed, it can only change) so the mental energy of humanity isn’t just the electric impulses in their brains but the psychic energy also is released. A dimension in certain position between our world and others started gathering that energy and thus the Gainen were created, representing concepts created by humanity.
The Gainen attacks were devastating, but one of the assistants of Eiyu Shomei brought a possible defense. He worked in the Gainen research and developed 10 Gainen Medals, objects that trapped inside one of the Gainen, so humans could use the same powers. He picked many candidates but only one managed to activate his coin, Hiro Yamanaka, a young man that was escaping from school bullies and accidentally entered the test grounds. The Gainen Medal of Piercing was activated and soon enough the other ten ended up, curiously, in the hands of his classmates. This happened thanks to the school being placed in a dimensional weak point that casually touched the Gainen Space and thus all the students were already in synch with the energy. Once activated the Medals can work with other hosts, as Reiji Fukuma demonstrated, when he replaced Yamanaka’s younger brother in the possession of the Gainen Medal of Striking. This group trained by the military leader of the JHWAB, Kyoshi Kenmei, currently headmaster of Inazuma Gakuen. The Anti-Gainen Taskforce (Gainen Satsujin Tai or GStai for short) defeated the scientist and his Gainen Slaves.
Apart from minor uprisings such as the Kaze Ni Nare movement, that tried to release, in several occasions, a corrupted Dai-Tengu called Arashi and other strange sects, nothing bothered the JHWAB from the beginning of the eighties until the present, but that peace, or at least routine was interrupted by the discovery of the location of Ryugu-jo and the release of survivors, genetically engineered Half-Bloods. This group, who referred to themselves as Myth Soldiers or Shinwa no Heishi proved to be a difficult task to hide and to relocate, but thankfully a small village enclosed in a mountain valley was abandoned after the 2011 Earthquake and the radioactive crisis. The MS were immune to radiation and after cleaning up a bit they installed there, now many of them work for the JHWAB or the Government and Roshi, still the head of the Bureau hopes that they will become what he expected so many years, a way to join both worlds. The village was renamed Shinwa-mura, and is technically independent from the Japanese government, being similar to an embassy. The MS aren’t scared of humans and allow the free pass to their town, that slowly is becoming known and turning into a tourist location, but still haves restricted access, allowing only scientist or important people.
Currently the JHWAB is divided into 4 different sectors, Militar, Economic, Intelligence and Cultural, all led by Roshi Yasumori, each department is led by members of the 8 Taisho Clans and haves some agents under them. There are also many human officers and agents that handles the most tedious tasks or the hoaxes, some of them even without knowing that most of what they consider a myth is real and sometimes in the same room as them. All of the officers and agents are linked to the Ministry of Defense, currently lead by Minister Iyana, a not very bright individual that thinks himself much more important in the grand scheme of things that what he really is.
Omnyo Master, Sage and Leader of the organization, he is almost 110 years old, making him one of the oldest and most powerful Omnyo practitioners alive, he is known for his ability to summon massive amounts of Guardian Demons thanks to his good relation with every Hidden World Faction. He is a man of infinite patience and kindness, always trying to help others and trying to find a pacific solution for all conflicts. He may not seem so old, but thanks to many Gifts granted by minor deities and other powerful beings his life expectancy is unknown, he seems to have the body of a 50 year old and the face of a 60 years old. He lives a very ascetic life, almost monk-like; his only priced possessions are his father’s walking staff and his moustache, who he loves as a son. He haves a very extended family, most of them following his steps and convictions. He knows the names of all who work for him and almost all the Hidden World population of Japan, the only group he dislikes is the Kitsune clans, considering them to be a bit too prideful and arrogant for his tastes, but he tends to keep his mouth shut.
