Speed☆Star (速☆星, Supīdo☆Sutā) is a technique used by Black☆Star and Tsubaki in her Mode: Ninja Sword transformation.[1]
Overview[]
With the sword's small size, this technique allows one the capability of moving at extremely high speeds to the point movement cannot be seen. This allows for rapid attacks and quick evasions. With this form, it also allows to better engage in close combat, a strategy best suited for a Ninja Sword. However, this technique comes with a price: It can only be used in an environment with good grip. If friction is too poor, the technique can backfire. As such, it's best not to use this technique on rainy days.[1]
