Demon Sealing Ninja are ninjas responsible for sealing magic and Sealing Demon Gods, and are also ninjas who have sealed the "Demon God's Power" within themselves.
This is a special force established by the first generation Lord Oda, formed from select elites among the natives, and constitutes a Direct Affiliate Ninja Army tasked with hunting down "Demon Gods from a Different World," "Demon Race" lurking among humans, and retrieving "Magic Artifacts" from other worlds. There are some overlaps with what the Monster Company does, but the internal Imperial Court Surveillance was more like a side business after most of the "Demons" in this plane were sealed.
