Research Facility B

Research Facility B is a secret military facility in Japan, which researched artificial abilities. It was modeled after Research Facility A, which was destroyed in a massive explosion.

Description
The facility is located in the countryside outside Yokohama, where one must pass through an unpaved mountain road. Built in an isolated area surrounded by greenery, the facility appears as an abandoned old shack. It is a barn with rotted wooden walls and blackened posts; equipment for hunting and farming are also stored inside it.

However, the barn hosts an elevator that brings users to a deep underground facility with dark concrete walls. A small security station is located somewhere following the entrance where armed guards examine incoming users' belongings and perform a blood test on them. There are various turns along corridors to prevent any gunfire from traveling great distances. As deliberated by Adam Frankenstein, the facility is designed for intruders to have difficulty in looking what they are looking for, befitting its nature as a top-secret facility.

The facility runs on a fuel supply system, which grants control and command to other facilities. It also has an automatic disposal system, which shuts down the facilities' operations when in progress, as well as life-support, security, and main memory systems. Moreover, there are at least five computing cores in the facility.

Research Department
Located underground, the military research division is relatively spacious and where most researchers operate and practically live. It houses various electronic devices that are protected from hacking and rejected external communications.

N's Office
Further into the division is N's spacious office, guarded with an automatic door and has a back window projecting a view of the beach. Oak bookcases tower from the floor to the ceiling, filled with technical books from around the world. At the back of the room is N's antique desk and a screen that flashed surveillance video footage. Upon descending the stairs lies an room at the bottom floor, where an iron sliding door can be operated; the door is bulletproof and explosion-resistant, only able to be forcibly opened by a handsaw to a fault. Beyond it is an elevator that can proceed further underground.

Research Facility B
The actual Research Facility B is located deep underground below the bottom floor. It is based on Research Facility A that was destroyed during Arahabaki's rampage near the Yokohama Settlement. Built at the end of a hallway, where dirt and dust piled over the years, the room's door is covered in various yellow notices.

The interior of the room appears like a massive factory, and a mesh foothold lies between the floor and the ceiling and surrounded by railings. Like its precedent facility, it also contains a wide, ceiling-high cylinder where they kept Chūya Nakahara's clone shackled with silvery-white chains, which was filled with a bluish-black liquid that made its glass surface seem opaque when viewed from outside.

Storage Tank and Observation Room
The large storage tank is used for storing water for laboratory emergencies. It was the size of a school swimming pool, which was almost devoid of any furniture and equipment save for notches carved into its walls to measure height. A monitor hangs from the ceiling, which can be seen from the observation room.

This observation room contains about 20 chairs and several gauges for devices, including a microphone. This is where N and other researchers observed and operated on Chūya in their attempts to make him release Arahabaki of his volition.

Storage Room
This storage room can be locked with an encryption key. Adam once hid Buichirō Shirase inside one of several weapons lockers and switched the room's lock with a key that changed after some time to keep him secure.

Panic Rooms
The facility has a few panic rooms reserved for top intelligence officers for evacuation purposes. Their heavy doors have electric locks and are resistant to explosives, chemicals, and abilities. Each panic room is a long, narrow chamber shaped like a rail carriage, supplied with a communications terminal, food, a generator, bulletproof vests, and emergency essentials. They are also equipped with single-passenger elevators for evacuating. They also have a highly secure established connection to the facility's security system for the evacuees inside to issue orders from inside.

Control Room
The control room serves as the Operations Division's base for security and monitoring purposes.

Background
After Research Facility A was destroyed in an explosion caused by Arahabaki, Research Facility B was built and modeled after the facility, where researchers continued their study on artificial abilities in secret.

King of Assassins Incident
During the incident, N invited Chūya to head to the facility to tell him about his alleged origins, albeit actually to dispose of him. In the fiasco that occurred not long after, the facility was heavily damaged due to the clashes with several parties, mainly Chūya, King of Assassins Paul Verlaine, Europole android detective Adam, and the facility's combat personnel. Notably, Verlaine blasted a panic room's ceiling and soared aboveground with N, leaving the facility in shambles.

In the aftermath of its destruction, an inquiry committee from Europe tried to look into the facility, but the Japanese government refused entry, given the facility's possession of top secret research on abilities.
