Quick-relief chair (Pixiv Fanbox)

Working in the dungeon can be quite taxing. Whether it is a trainer, part of the cleaning crew or within the administration - there's just too much work. A great way to get rid of some stress is to make use of the thing the dungeon is famous for. That's the reason we developed quick relief chairs, as a punishment for misbehaving trainees and a reward for overworked dungeon staff. Trainees are placed in the chair with their heads peeking out from the top, leaving some space for our staff, who can then in return make use of the trainees' mouths any time~
