Shinsengumi

They were the most Elite of the whole Bakufu. made up of 10 groups headed by captains, and over seen by the leader and vice leader they patrolled Kyoto by night and killed Ishin Shishi men. the motto AKU SOKU ZAN was actually the motto of the whole Shinsengumi. most trained in the Dojou started by Kondo and Hijikata the style was called Tennen Rishin Ryuu. a break off attack style called Hirazuki which is a right handed horizantal thrust. actually Saitou Hajime's Gatotsu which it isnt called btw was litteraily at Left Handed Refined forward Thrust.

 

but...
No! The Hirazuki was a left-handed stab, not right-handed...

Gatotsu was based on it...

I do wonder how Okita's 3-point-stab looked like...

 

hmmmm u may be right im not quite sure ^^;;; anyway its probable that Okita's Three Step Pierce was directed at the neck and both shoulders so its assumed that it looked something like Sanada Kohjirou's three step stab from the game Last Blade 2
