City council chief Backeshof, one of the best merchants in all of Aitheria, has set his eyes on purchasing Nobu. Shinobu stubbornly refuses his offer, but he responds by informing her that whatsontap is actually an illegal alcohol. If that is true, then that means that they've been violating the empire's law this entire time. Not only could Nobu get shut down for good, but Nobuyuki and Shinobu could find themselves sentenced to death!

One day, Johann=Gustav swings by Nobu with a dignified looking old man at his side. The older gentleman savors whatsontap with a smile, excitedly trying all sorts of different dishes one after the other. Pickled small horse mackerel, panko-fried Spanish mackerel… The older man is overwhelmed by the multitude of exotic dishes he's never tasted before. Supposedly, this strange gentleman is Johann's uncle, but who is he really…?
