Shikai ability:
The Shikai gives the user the ability to reverse the age of anything it touches by 50 years restoring  them back that many year if they had a missing arm or is poisoned then its gone. But if I get knocked out any thing  that was restored gos back to normal so if I healed myself when I lost an arm and I get knocked out then my arm disappears or if I'm poisoned then the poison will come back. Also when I release into Shikai I get the strange abilitys to geuss just about how old things are.
Bankai ability:
The sword becomes longer in length aswell as giveing the user a pink coating around there feet boosting there speed ten fold. Just like Shikai it has the ability to return the thing it touches back years instead of fifity its 250 also it can shoot beams at the target that glow light blue when the beams or balls touch something it returns 200years. If the sword it self touchs you in bankai form then you get age poisoned were you become 5 years younger every 30 seconds.
Shikai release: (what do you call out when you 
Modo lets make them return to there youth.
Bankai call:
Modo modo bring them back to before they were born
Detailed description or picture of Bankai and Shikai:
Shikai it looks lake a needle like sword that is very fast and can't slice but is better for piercing and going for Improtant organs . 
Bankai it's shape gets long and it develops sharp edges while still having it's needle shape.
Weakness: it has to make contact with what it wants to return so that means if your faster and I can't cut you then I can't reverse you. Also if I have touched you they way to become normal again is to knock me out  if you kill me you stay the same but if I'm knocked out it reverts you back to your normal age.
 Every thing that was restored or reversed gos back to normal if I get knocked out it is never permanent unless I kill you.
