New champion

This is a champion idea and I kinda want to see what the community thinks about it. Is it good?Bad? Overpowered? Lame? Feel free to give feedback. The champions name is lost to the ages, shrouded by the betrayal of his teacher and greatest companion. They shattered his blade before his very eyes within his last seconds of life leaving him. Death however rejected I'm and he rose gaining the name yurei ( based off the the Japanese folktales) He can not seek rest until he has claimed vengeance on the people who have done him wrong. (rough backstory gonna keep working on it).his sword would be shattered and the blade shards would dance around him resulting in his passive which would either a. Do a small portion of damage as long as a champion or minion is within said area and scale slightly with ad. His q would launch his blade shards in a straight line if it hits an enemy champ they imbed themselves dealing a small portion of damage and upon reactivation, would rip out and cause a small bleeding effect. His w would send the shards out in a line and root any champion hit for a short duration. Upon activation of his e the blade shards will race to defend yusei at all costs creating a small wall and absorb either one ability hit or would reduce/mitigate incoming basic attack damage for a short duration. For the ult the blade shards would snap together, reforming the blade, and either a. He gains tremendous speed and leaps out cutting through anyone in his path with a decent range and the return once again back to his original position. (I don't really have the drawing skills to illustrate this but imagine the length of a fully charged xerath q the tip of that would be where he'd end up first for a split second then leap back to the original position. ) B. He could dash multiple times (upon reactivation) damaging any enemies he pass through. C. (This one I came up with recently) his sword extends a great length and raises it high and after a short delay brings crashing down to the ground damaging any enemy caught in its path. Again. Feel free to give feedback. also if you like it feel free to share the link to this page with your lol friends. (also if you can find any artists willing to help out even if for a small fee i'd be grateful.)
