The Yosan Shuka group composed of Mao, Leon, Shell, Shilou, and Mei Li are off to their first destination in search of the legendary cooking tools - Shanghai.
There they are reunited with Sanche, an old friend who is now the head of their family restaurant. However, the happiness ends soon when the team finds out that the Underworld has already reached Shanghai. They declare war on Mao and his team-mates and takes Sanche’s father and the other elders of the Shanghai Cooking Union as hostages. The Underworld asked for four chefs who will compete with them. The price for the challenge is the map indicating the location of the legendary cooking tools.
The team then agreed to compete. They were blindfolded as they were transported to the “Lou Lin Vessel” - a large cooking arena built by the underworld.
为了寻找其它七样传说中的厨具，小当家一行人来到了上海。想不到竟被误认是黑暗料理界的人差一点被处以私刑，所幸阿Q的出现化解了危机。不久黑暗料理界便挟持人质，要求小当家与三名厨师与他们进行一场对决。面对黑暗料理界巨大的水上城堡——楼麟舰，小当家等人是否能击败黑暗料理界呢？
「伝説の厨具」収集に出たマオ達。夜はサンチェの店で歓迎会が開かれる。そこへ裏料理界の料理人が現れ、上海厨師大連合会を人質にとり、伝説の厨具の封印地を示す地図を持ってこいと告げる。
