Koku Shundō (虚空瞬動, Void Instant Movement) is a movement technique where instead of using a fixed surface, the practitioner simply uses ‘air’ (space) as a foothold. As this can be performed in mid-air, movement in any direction is possible, eliminating the base weaknesses of Shundou. Not quite the equivalent of flight, but a necessity in high-level battles.
