Level C

Level C (レベル - C Reberu C) is a high level within training facilities all around Japan. As a level with trainees of control levels ranging from 22% to 27%, a trainee from this level is automatically legible to advance into the military's ranks immediately, without the need to graduate or to go onto Level D. Its training regimes are similar to that of the Level A regimes, except they're not as cruel and harshly executed.

Level C Controllers
Currently, there are no known level C controllers introduced in the series.

Development
Little is known about Level C, however it is known that in order to be accepted into it, one must possess a control level of over 21.5% and will eventually graduate from it and onto the next level once they reach 27.2%. It is also known that joining the military ranks from the level is acceptable.
