June 15th, 2022. In Prince Morinaga's Dungeon.
The dungeon was a place to keep hardened criminals, each and every one of them would've stayed there, waiting for inevitable execution. Heresy, Treason, Witchcraft... You would be placed here like a rat on a wheel for any of these "crimes". At least you would a few hundred years ago. Today? The Dungeon is an abandoned tourist attraction that lost it's edge and gave off an eerier vibe as the years stacked up on it's age. There would be a small shrine out front, no bigger than a boar usually is, the shrine was used to 'entrap' the spirit of the late prince and have him watch over his origin of sin as a guardian. Right next to the shrine there was a huge sign ordering: "Stay away, trespassers are at risk of death."
During the war, with the tourists too occupied to approach a failed attraction, the dungeon was used as the Republic's hidden base of scientific experimentations, this site was called Akuma noKangoku, AnK Site for short. This base was used not only as a cesspool of experiments for world-renowned scientists who wanted to make a difference in the war, but a Black Site harbouring Japan's most dangerous underground.
In this laboratory of sorts, stands the General of the SFGp, Kagetsu Jin, acting as commanding officer. Surrounding him was; the leading officer in charge of defending the site, known as Masayoshi, the Commanding Officer of the Military Police, as well as Lead Scientist and Lead Engineer, Tenkai and Hakari Kyō. Kagetsu called them together in the centre away from their respective positions for a meeting, something about a psychological weapon used for information, something so terrifying it can extract anything from anyone and leave them broken.
"Destruction, madness, heads flying off into the sky, holes in the hearts and lungs of our men and pikes impaling the spines of our people." Kagetsu announced. "I have given each of you three months, three months for one thing that could decide the fate of the Rebellion forever, I hope you have brought me something of value."
"Of course, Sir." Proclaimed Tenkai. "The tests have been completed, we have already extracted useful intel from a captured rebel and are continuing said extraction. It works like a miracle, with this we could win the war in a matter of months and with minimum casualties too. The rebel soldier will be executed once we are finished with him, rest assured, he will not make it out of this place with his life. Although, what should we do with Subject Rei?"
"Leave him, he's a jammed gun." Said the General of the SFGp. "He'll starve. We'll leave him for death to take soon enough."
Subject Rei was the codename for the first participant used as a toy for the weapon, it was said that Subject Rei had no actual name, his only current purpose was the help facilitate the engineering of this project, his 'contribution' to this project was to indirectly point out the flaws and weak points of the armament.
Subject Rei had long black hair 'til the end of his neck, however not on the sides, sort of like a wolf cut, he always made sure he could see his left and right clearly. It is said that he did not speak, and that he had the face of a God of Beauty, his personality was dull, quiet but intelligent, and his life was anything but colourful. To be used for the sake of the success of your country is one thing, but to have your sanity forced on the line for a gamble is another. Outside his cell was a note from the warden; "Heavily dangerous he lays here, the Devil."
On his left pec was a scar, chipped away at by a shiv of sorts, you could just barely see a tattoo behind the scar, as if he was trying to cover it. He had both arms shackled and raised up, held together at a distance by chain to a metal bar. From time to time, he would be taken for medical examinations, and a therapist for 5 minutes. It was the least the Republic could do, they did not want to be seen as a villain so they gave him the most minimum amount of care possible instead of giving him none. All the other prisoners were also quiet, they were not used for experiments like Subject Rei, they were held there against their will, having committed no crime but being too dangerous and skilled to stay above ground on the President's sacred lands.

After over a week and a half of gruelling torture, the Republic had found out of a secret way inside the citadel connecting to an unarmed military base used for basic patrol meet-up. The base and the outside was connected by one underwater system way below ground level, a normal human couldn't hold his/her breath in long enough to survive the journey there. The Republic sent groups of submarines outside of agents filled with infantrymen in the numbers of a thousand or more, and with a couple more waiting outside the gate for them to enter after the pinch.
June 28th, 2022.
Half of the citadel was completely destroyed due to vast amounts of munitions, the room containing rations and armoury was completely bombarded to smithereens, sending the Rebellion back years. No food was coming, nothing to defend yourself with except a bayonet, but that didn't do much good, not against these numbers. The Party Leader was driven back with his men and took refuge in Shimane, backed up against only water and open to navy attack. However, they had set up a quarantine around the water with sea-mines, making any vulnerability from behind fictional.
June 29th, 2022.
A remnant of the Rebel Party had snuck inside countless prefectures while the Republic had attacked their main fort of operations, one of which was the Kanagawa Prefecture, holding the special black site and all it's ogres and demons. Within 12 hours, the prison guard were instantly executed by gunmen, the usual defenders of the site had assisted in taking down the citadel and were a long way. In a hurry, one of the infantry men spilled booze all over the gate and floor, lighting it on fire with a spark of his bayonet, the whole site was engulfed in minutes, which each and every member retreating, killing each other in the gruesome process.
What came out that day, was the curse that was placed from the desperation of the Republic and the sins of the Rebellion, a platoon of phantoms. In the middle was a man with a scar on his left pectoral, and a black samurai's mask on his head. He was dragging an o-dachi as long as his whole body, chipping away at the floor. Behind him was a bear-like mammoth of a human, grinning from ear to ear. On the other side of him was a short fellow, holding dual sickles and slipped around the fire like a snake.
In the beginning of July 2022, a third-party faction came known, feared infamously by both regiments of Japan and the population itself. This faction became known as the Wraiths of Kanagawa.
