There was one hollow in particular that was extremely angry after regenerating in Hueco Mundo.

Not only was his first scheme foiled, but even after obtaining a powerful body he was defeated.

If only Ichigo hadn't shown up and ruined his plan. Haruko was an extremely powerful body.

But it wasn't enough...

It was time for the tapeworm hollow to be at the top, but he couldn't do it alone.

So now he's going to return to the human world in order to gain his and another body.

But this time, he was going after Ichigo's friends.
