Kagurabachi — Iai White Purity Style

After seeing Chihiro send Ikura away with the key, Hiruhiko immediately clues on that Chihiro has a plan to help Iori escape, and presses the button for the elevator next to him. Refusing to let Hiruhiko head upwards, Chihiro speeds forward to attack, but Hiruhiko blocks him, Chihiro realising his speed is still insufficient. It is revealed that many years ago, master swordsman Itsuo Shirakai held the view that the swordsman who was the fastest would be the strongest, developing specific stances to achieve the fastest movement and slashing speed possible.
