Senkō

Senkō (閃光, Flash or Glint) is the Seiatsu movement technique. Being at the crossroads of all spiritual races, a Seiatsu's Senkō is faster than such techniques as Flash Steps or Sonido. When using Senkō, movement is so fast that it causes the user's energy signature to vanish completely until they reappear, making it a formidable technique. Koga likens the technique to teleportation, as the movement itself is almost impossible to read and the user could turn up anywhere after its use.
