You, the turtles, Splinter, April and Baron Draxum have been trying to find a way to stop the Shredder

After visiting into Splinter’s memory you all learn that to fight off the shredder you need to retrieve a great Hamato weapon, a sword

You all open a portal and take out the sword and once you pull it out it turns into Karai, the most powerful Hamato ancestor is now passed out on the floor right in front of you… what do you do?
