On the left hand when holding grip you make a fist and on the right hand a chef's cleaver(nanami's blade).
The grip+trigger ability would be a damage enhancer that covers the hand/weapon with a somewhat jagged yellow aura, somewhat enhancing dmg by 10%-15%.
The ultimate ability would be a purple aura that surrounds the user and extends about arm length and does tick damage to all hostile creatures within the aura and further enhances attack power by 50% at the cost of speed and jump height, the ult would last for around 30-60 seconds and the damage would be based on the level of the soul.
Last stand feature:when reaching level 22 you are able to use ult without full hp but it makes up for the absent ult with health at a 1%hp=1%ult ratio
(example:if you have only 50% ult it will take 50% hp to make up for the ult, another example is if they have 64% ult and use ultimate they will lose 36% hp and use ultimate resetting their ultimate bar and giving them ult, a final example is if they have 0% ult and use ult it will take 100% hp killing them or 100% will take 0% hp)
