Special Chapter: The World Pirate Is Coming, Intersecting Worlds.

Touma, Mei, Rintaro, and Kento are all staring anxiously towards the sky when just then a shooting star descends from up above! However, the shooting star falls towards Touma! "Successful landing, Orihime World! Good work!" It was not a shooting star that fell, but a mysterious monster from another world!
