( 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 speeds equal to the A ranked use 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. This technique can still be physically reacted to if the opponent is of similar speed to the user.
Note: Only useable by Samurai bios.
Note: Only useable four times per battle.

( Bushidō ) - Way of the Samurai
Rank: S
Type: Supplementary
Range: Short
Chakra: 40 ( -10 per turn )
Damage: +30 to Kenjutsu and Taijutsu
Description: Samurai quickly learned that Ninjutsu would be a very dangerous weapon, and an incredibly difficult one to combat. But, they soon developed a countermeasure that helped them combat the ever-growing amount of Ninjutsu users: infusing their armor with their own chakra. By releasing their chakra into their armor, Samurai infuse their armor with special properties, protecting against energy based attacks up to 30 damage, and physical jutsu of 40 damage and lower. This works by creating an invisible overshield of chakra around the Samurai’s body, using their chakra to augment their armor to help protect them. Due to the spiritual nature of this technique, harmonizing the Samurai’s life energies with their armor, and bringing the user’s Bushidō to the forefront of their mind, preventing Genjutsu of up to A rank from targeting them. This increase of chakra also augments their physical prowess, tripling their speed and granting a large increase to Kenjutsu and Samurai jutsu. However, upon ending, the Samurai is unable to use Iado and S rank and higher Samurai jutsu that turn and next due to fatigue as well as only two jutsu the turn it ends.
Note: This jutsu lasts 5 turns each use and is capable of being used 3 times.
Note: Only usable by Samurai bios. No summonings can use it, even if they can use other Samurai techniques.
