Cryogenic prison

Located in the section of the Sector Seven's headquarters, a cryogenic prison (超低温牢) designed by Kokonoe, created specifically to restrain Azrael. A prison that was more akin to a tomb, where the temperature is close to absolute zero, a room covered in frost and ice. It is here that Azrael had spent two years while remaining imprisoned in cryostasis. He was released in January 15, 2200, at 19:19, by Sector Seven's scientists.
