Mugendiai

Mugendiai is an unique sword technique created by an unknown Iai master.

Overview
Mugendiai is not a branch of swordsmanship, in fact it naught but a simple elaborate and dangerous technique that can have many applications to the style of any given swordman, the only requirements are:


 * A Sword
 * Kenbunshoku Haki and a strong will
 * Fear of their own power
 * Ability to create excessive amounts of blood lust

Preparation and Performance
To use the technique one must be able to create massive amounts of blood lust and "direct it" at the sword one wields while it is sheathed. Then before drawing it one should use their kenbunshoku to imagine themselves getting cut down with their own sword over and over again to imprint the sense of death on themselves by their own hands. This preparation not only triggers the flight of fight mechanism but removes any other mental restrictions allowing the user to literally cut down even things they themselves mentally wouldn't allow them too, such as traumatic enemies, friends, family.

By awakening the inner most basic fear of predation and death one can then wield their sword and cut down everything in their path with speeds that far surpass the normal Iai. Because of the physical and mental limiter removal the practitioner will generally not only cut once, but proceed to slash upon their target tens of hundreds of times.

Problems
To use this technique is to momentarily abandon their humanity, and thus comes with the big price of mental instability, users of this technique tend to become less and less humane the more they perform it unless they have a strong enough will.

However when one uses this technique it has a chance to fail if their desire to use this technique is smaller then their desire not to. If the user is unable to be more scared of their own power then their wish to not use the technique it will fail. This barely presents a power to veterans who have already lost most of their humanity.
