Side Story: Thor, Mabel, Lukie, and 'The Hero of the Hero's World'

"Thor-sama, Thor-sama."

"What is it, Mabel?"

"I found a strange piece of paper in the corner of the storeroom. Would you take a look?"

One day.

Mabel, who had been cleaning the storeroom, brought this up.

She was holding an old piece of paper.

Judging by the photographs on it, it was probably from the Hero's world.

It looked like a page torn from some book.

"I can't read it. What does it say?"

"It says, 'We Buy Hidden Treasures.'"...
