A mysterious Fûma ninja; another survivor of the Manji clan. Nki almost never makes himself seen, and when he does, his face is always covered in bandages. Due to Nki's scarcity and covered appearance, it's unknown whether or not Nki is truly male or female. He appears to be watching over Mekkimaru (which was in the possession of the Manji clan until Toki, with the assistance of Nobunaga, stole it in 1574), and appears to be close to Toki himself, but it's unknown how he ended up occupying that position in the Fûma village in the first place.
