Isekai Izakaya "Nobu" (The Emperor and the Queen Regent of Oilia)

"Nobu" is an izakaya run by the head chef Yazawa Nobuyuki and Senke Shinobu and is connected to the other world of Aiteiria. The former emperor, who is also a customer at the izakaya, is pushing for an arranged marriage between his grandson Konrad and Celestine, the princess regent of the enemy country of Eulia.

Meanwhile, Celestine, who had come to Aiteiria after accepting a political marriage for the sake of her homeland, Oia, was heading for the izakaya "Nobu" to try the "kushikatsu" (fried cutlet) that her spies had reported was delicious.
