The Secret of Whatsontap: Part 1
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!

Isekai Izakaya: Japanese Food From Another World
Izakaya “Nobu” is a modest establishment, staffed by only two people: master, Nobuyuki Yazawa, and server, Shinobu Senke.
Despite its humble appearance, its entrance is mysteriously connected to an ancient city from another world: “Aitheria.” Nobu’s patrons consist of lazy palace guards, incognito clergymen, and the Waterworks Guildmaster – certainly not your average clientele!
But once they enter Nobu’s doors, they are greeted with the finest alcohol they’ve ever tasted and dishes the likes of which they’ve never seen. With the food plentiful and the drinks flowing, the patrons leave their troubles at the door as they call, “Give me a cold ale, master!”
