Totsuzen Katana is japanese for Sudden Sword
Totsuzen Katana is the sword of Hitori Katachi, the Lone Figure
. Totsuzen's aerodynamic qualities allow Hitori to sprint at extra high speeds (this includes when he is jump stepping). Totsuzen also is built with an engine inside (as can be told by the exhaust pipes protruding upward in back). This also allows for greater running speed along with greater swinging speed thus resulting in more power on hit. It also has special properties that allow Hitori to summon it at any time (or just bring it to his hand (like the force from Star Wars)). It's sleek design and red/black color scheme also makes it a perfect match for Hitori.
