Right ok, so theres Iaidō, Iaido: Kyūban sōdo and Iaigiri which are all based on Iaido.
Iaido is the quick movement of drawing and striking with a sword and re sheathing it, quite often seen in movies, anime etc. Apart from looking pretty cool, when used in close range of an opponent it can even prevent an opponent from weaving seals. It has a short range, where it generally can be seen as a quick dash forward, draw, strike then re-sheath.
Note, (which more specifically doesnt really apply to you, but jsut for reference) the speed of the technique is relative to the rank of a user. So coming up against a Sage using this, they may be able to use it quicker than you, however you will be faster than anyone below your rank.
(Iaidō) - Art of Quick Draw and re-sheathing the sword

Chakra cost: 30

Description: Iaidō is a form of kenjutsu where the user quick draws the blade extremely fast to strike, then re-sheathing it.

Iaido: Kyūban sōdo is the same technique, but with the blunt edge of the blade performing a non leathal strike. Useful when keeping an opponent alive, preventing a lethal strike.
Iaigiri is the same strike, but more specifically in a downward slash.
(Iaido: Kyūban sōdo) - Art of the Quick Drawing and Resleathing: Sucker Sword
Type: Offensive
Rank: A
Range: Short
Chakra: N/A
Damage: 60
Description: Using the basic application of the quick drawing method of Kendo, the samurai will draw their sword at blinding speeds equal to the ranking speed of the orignal Iaido Technqiue. But rather than slashing the target, the samurai will turn the blade to the duller side and smash the blade along either the neck or the head, which can even knock the target out if done so. This is done with incredible speed and brute force in conjunction with using the blunt side of the sword.
Note: Only useable by Samurai bios.
Note: Only useable four times per battle.
