Yokai

The Yokai are lead by Nero, the Leader and Demon King. It is the name of the Unit of individuals which answer to her as their direct Commander in times of crisis, combat, training, and so on. Although members may volunteer to become Yokai, it is up to Nero to approve them or not. She only chooses those which prove that they are capable of working especially well with her and other Yokai members under pressure.

Overall, they are one of the strongest combat Units, and their assignments and tasks greatly vary.
