Summary
Rohan is called to the home of Ikkei Gozan, an antique dealer with whom he was acquainted with, under the pretext of "I want to show you a strange item." He places an item wrapped in in front of Rohan called the "Happiness Box", which apparently has happiness packed inside. Rohan becomes angry thinking that Gozan was scheming something and is about to go home without touching the box. However, the furoshiki wrapping suddenly unravels itself to reveal innumerable ceramic pieces.

Rohan becomes irritated that he was falling for Gozan's trick. He then understands that it is actually a puzzle and could only be assembled by someone with special talents such as a Stand user. Thus, Rohan starts assembling the box out of curiosity.
