Bankai: "Pierce the minds of my enemies, Ki ni piasu Kiba!"

In the first form Kirito is able to utilize the genjutsu ability, the fang necklace becomes one or two hand held jet black daggers, one in each of his hands. The blades appear in Kirito's hands at his reaction speed. In this form, the daggers maintain the stat boosts that the shikai give, however they loose the healing abilities and the ability to cause any physical harm. Instead the blades gain the ability to put anyone they even nick into a strong genjutsu, the blades phasing through the opponent instead of causing physical harm. The blades only phase through people and not other physical constructs so they may still be used to block swords, kunai etc as well as interact with other things. This Genjutsu has a power of 200 and can have any effect desired by Kirito's will exceptions being death and comas. Because of the strength of this genjutsu, it requires at minimum 3 tomoe sharingan or a chakra stat of 200 to dispel it. The genjutsu costs 150CP to activate and lasts until broken or dispelled with a cooldown of number of posts used. This Bankai form lasts as long as it is in dagger form with an upkeep of 30CP and has a cooldown of 3x number of posts used.

In the second form the bankai stays in the form of the fang necklace and does not allow Kirito any access to the daggers or the genjutsu ability but instead grants him +150 to his main stats, ie chakra, health and speed. This form of the bankai lasts until Kirito says the phrase "Return to your slumber, Iyashino Kiba." and has a cooldown of 4x number of posts used. The upkeep for this form is 60CP per post used.
