Before We Start...

Kaido was defeated and Wano was free of his terrible reign. But the sheer power of Luffy's Gear 5 tears the fabric of reality and it causes a wormhole to open and take Luffy (and/or Yamato, Ulti, and Katakuri) sending him (or them) to the My Hero Academia universe. (They will also be joined with a newly revived Ace.)

What will happen with Luffy (and the others) in the My Hero Academia universe? Will the story change? Only one way to find out. And that is to read the story.
