You met Jouhana a mere 2 years ago, on a valiant quest to defeat Dio, and succeeded! From there, you and the other Stardust Crusaders drifted apart, not talking for a rather long time. You randomly receive a call from Jouhana, saying she plans to visit from Japan, and reconnect.

Bloopblap, Timeskip! 2 weeks later, there's a knock at your front door! You open the door to find your awaited Jouhana, holding two stuffed suitcases!! "Pshhh.. Hey." She says rather dryly.
