HMP Irongate

**Her Majesty's Penitenciary Irongate**, abbreviated as **HMP Irongate**, is a maximum security prison on the island of Iwo Jima, Japan, built secretly by Great Britain to experiment the extra-harsh way of prison management. Now it was abandoned due to tensions between the US and Japan.

It is the core of the protagonists' activities during the ongoing Eldritch Outbreak, and most SK characters live there during the event.

## Structure

The Prison covers the whole island, is surrounded by the sea in Alcatraz's fashion. It's structure is composed of two perimeter walls with a jeep road between them, and large steel gates leading to docks and warehouses, giving the prison its name. The perimeter walls are mounted by Mirador towers, and, out in the sea, there is several towers emerging from the water with Anti-Aerial auto-cannons.

The Compound is composed of 8 cell block wings and curved buildings around a core tower, the compound's nexus, with hallways linking them to the others and the nexus itself. The nexus links the cell blocks to 4 wings around them with hallways, each wing serving a role in the inmates' routine, such as a work wing, a visitation wing, a leisure wing and a Solitary Wing.

The curved buildings between the nexus and the cell blocks serve as the canteens, kitchens, and infirmaries for the connected blocks, each security level having its own kitchen, canteen and infirmary, and the nexus is where rollcalls were done.

The Administration, the Security and the Maintenance wings are connected to the compound's visitation wing. Each wing and block of the prison has blast doors at their entrances and exits, and there is CCTV cameras everywhere, even in the cells.

The Administration wing has the Warden's office, then the Lawyer's, the Accountant's, the Psychologist's, a common office, and a Staff Room and bedrooms for them and the management workers to rest. The Security wing has the Security Chief's office, the main Security Office, the Armory, the Big Brother room where all CCTV monitors are, the Kennels, an Infirmary and the Security Staff room and dormitory for guards to rest. The maintenance wing is composed of multiple buildings, such as one with the Foreman's office, the maintenance staff room for workers to rest, several buildings are warehouses and multiple other ones are the Prison's Power Plant.

## System

The Prison was a maximum-security facility with zero-tolerance policy where the most dangerous criminals were sent. Cannons automatically shot unauthorized ships and aircraft to sink them, and the boat leading to the Prison was checked regularly to prevent escapes.

The prison's routine lasted each day from 9AM to 8PM, and there only 1 hour of free time. Guards were armed with stun rods and tazers that stunned even the strongest prisoners, and were equipped with body armor and specially trained to deal with them, thus inmates had no way to resist to even one guard. If a riot was attempted, the prison sends special teams such as the GABOS Armed Guards in extreme cases, ranging from the Riot Guards with shields and stun rods to the Armed Guards with shotguns and assault rifles shooting rubber bullets, all protected with tactical armor. Guard dogs were used to detect contraband and catch running inmates, and the CCTVs not only allowed to record security footages but also could automatically recognize a firearm and who was holding it.

The Prison's Miradors were occupied by several snipers that shot at sight on deviant inmates, and that warned the Security office of security issues such as incoming gang boats.

Inmates were divided in 4 levels of security each with their own canteens, kitchens, cell blocks and common rooms at the leisure wing. Each security level was given more or less privileges or penalties, the highest level being the most penalized.

The Prison has its security measures separated in 5 levels each represented by a Star, and the more stars there were, the more measures were taken, and at the fifth star, the Prison entered in Lockdown and sent special guards to deal with incidents, and the dogs were released. The security level increased slightly when an inmate missed his routine, and Lockdown was initiated when an escape attempt or dangerous behavior such as a prisoner holding a weapon was detected.

The Prison's logistics were made for it to last months without approvisionning, with enough workers to bring all kinds of supply around the prison.

## Abandonment

The Prison was abandoned as Japon, through aware of it since its foundation, started to disapprove the existence of a facility held by a foreign power near its homeland, and thus pressured the US and Britain to close it. Since then, the prison was empty and unused, through its cannon towers worked on batteries.

Once upon a day, a splinter group of Hiroshima Academy moved in the prison to find a safe and reliable base of operations since the main group was defeated.

## Eldritch Outbreak

During the Eldritch Outbreak, Henry, Ryōki and White along the Hanzō team travelled to Iwo Jima for safety from the Eldritch presence, but Henry's flying house was shot down by the Prison's AA cannons, and the Yuki Onna Henry summoned sank by the same cannons, but they achieved to reach the Prison's docks anyway, settling on them, with the Crimson Squad joining them a little later.

Ryōki entered the facility by the walls thanks to Henry's bionic arm, and put the power back on at the power plant but got ambushed by the Hiroshima splinter group who intended to grope and "kill" her for revenge. Henry, wondering why Ryōki wasn't coming back, entered the Compound but a CCTV caught her weapon and triggered the Lockdown procedures. Ryōki got rid of her assaulters thanks to stun rods, found Henry stuck in an hallway, reached the Security office, and disabled the cameras and the lockdown. As the Prison was functional and open for them, they moved in, Ryōki, Henry and White moving in the Administration block, where they founded the Guardian Sisters in the Warden's office. Mirai decided to take care of the prison's security while Ryōbi watched on the Miradors.

One day, the Hebijo team arrived on the Island, grievously hurt, and later, Yumi arrived possessed in several infected boats. Most shinobi tried to push her back, seeing she was possessed and a threat, but she injuried deadly most of her attackers, even Henry and Yomi, and tore the heart out of the chest of a powerless Ryōki, and that's when she was about to finish off Henry that Ryōki enabled her advanced Judge Blue form, and vainquished Yumi while healing everyone, through she fell unconscious for 3 days. The shinobi who didn't fight brought all the supposedly injured fighters to the Prison's Staff Infirmary.
