One motion. The sword leaves the saya, cuts, and returns before the opponent has finished stepping forward. Everything below is that one second, slowed to 240 frames.
No photograph, no render — a drawing, set out to the measurements of a real 71-centimetre blade. Scroll, and the ink lays itself down one part at a time.
Scroll drives the movement, it does not speed it up. Fling the wheel and the draw compresses instead of skipping.
Zanshin — the remaining mind. The cut is finished; the attention is not. Watch the space where the opponent stood until it is certainly empty.
