Looks Similar to this but with a more green tint.
Lore: Yakuzi's ancestors were part of the Shadow Transcendence clan. They were the assassins of the Ancient Lord of Shurima. They were infamous for their stunning dexterity and ability to get the job done. Though throughout history they have been known to take bribes and work for money. Tens of years before the time of Azir's grandparents, there was an assassin named Arashi who made the greatest betrayal in the clan. Arashi grew up in a small village and was taken in before he turned 11. He worked very hard, but he eventually turned evil. Doing missions that were dark and cruel beyond belief. Eventually, he believed it was time for a new Era for the clan. He worked with two other assassins and during the masters sleep, they murdered him. Once they became the leaders they began murdering innocents. When the Lord of Shurima found out, he banished Arashi and his loyal members to the depths of an unknown temple. Yakuzi's mother, Saturi, was Arashi's closest lieutenant. She escaped the punishment and had her child, Yakuzi. Together they started a new clan and terrorized the citizens of Shurima. When Saturi died, Yakuzi was made to become the new leader. But over the years Yakuzi was reluctant to murder with the other clan members, and started to secretly work against the clan, and when she became the clan leader she new she must end the clan's terrorizing once and for all. She created a plan to trap all of her clan mates, including herself in the same temple her father was sentenced to years before. The trap was a success. She spent her entire life fighting her clan mates, but when she was finally defeated, her spirit was captured by the rest of her clan, never to be released. Hundreds of years later she was secretly freed when Nasus banished Renekton to the very same temple. Invisibly she captured the souls of thousands of men in the current state of her clan. She has now moved on into the League, to finish her duty, and slay all of her clanmates.

Q: Yakuzi dashes to target enemy and leaves a mark of hatred on the enemy damaged. For the next 5 seconds Yakuzi gains 25/27/30/32/35% movementspeed while moving away from the target.

W: Yakuzi spins her blade in an ark in the direction of her cursor (close range). If she hits a target the cooldown of this ability is reduced by 55/60/65/70/75% of the current CD. Damage: 10/20/35/55/80 (+100% of bonus AD) CD: 7/6/5/4/3 Mana: 30/27/25/22/20
E: Passive: Autoattacking or hitting an enemy with Yakuzi's W gives Yakuzi a stack of Vengeance, max 7 stacks. She also has two different actives depending on her current health. Active Above 50% HP: Add one stack of Vengeance to all enemy champions in a large radius (from the outer ally mid tower to the second ally one in the mid lane). If they already have a stack of Vengeance on them, then add X more. (X being their current amount of stacks on them. EX: if they already have 1 stack, it will ad 2 stacks. If they have 2 stacks, it will ad 3 stacks and so on) Stacks last 7s. Active Below 50% HP: Steal all stacks from all enemy champions. Deal 3/3.5/4/4.5/5% of their current health in magic damage per stack. Yakuzi heals for 60/65/70/75/80% of the damage dealt.

Her passive cooldown is also reduced to 5 s (No matter what level you are(The invisibility from her passive overrides the R camouflaged making you briefly invisible unless you're under tower)
I hope you enjoyed this champion concept. All feedback is appreciated even if you only say "Yeah is good" or "It could use some work like..." Positive criticism is preferred as I would prefer if you didn't just say. "Sucks, it is a horrible concept." I would like to know why it "Sucks, it is a horrible concept."
