Nobuyuki Yazawa was once a chef at a high-end restaurant, but he is now the owner of Nobu. Shinobu Senke works as a waitress for the bar. She is bright, smart and pretty. The bar's cold beer "Toriaezu Nama" becomes popular and the bar thrives. Customers from Aiteria with various backgrounds like soldiers, merchants, and noblemen have a good time at Nobu.
