A national hospital and the one and the ultimate treatment center for those with Agonist Disorder. Those with Agonist Disorders are transported to this hospital after being taken into custody by the government.
Blocked off by a concrete wall, even at the 10 meter tall glass entrance of the hospital. Incoming and outgoing patients come and go by helicopter. Said to be located in western Japan and is some 3 hours away from Shikura by helicopter/car.
This place doesn't take outpatients; if you come there, you're going to be staying there for a while. In that sense, it's more like an asylum. Made up of a large compound and 5 wards (A, B, C, D specifically for those with A Disorder) and relatively small number of staff in comparison to the size (only in the hundreds).
