Kunen, the monk, decided to become a great disciple of Mantaro by joining a steak eating competition. But the appearance of an OPCE member jeopardizes his intention… What will Mantaro do when he heard about that?

After his loss in the Gourmet Grand Prix, Mantaro is now ready to challenge a new journey! Eat-Olympics, an eating competition that gathered many talented athletes from around the world is now being held in Taiwan. The first challenge is... a train lunch box?!

Mantaro smoothly completed all five shops! When the Grand Prix starts, he becomes the dark horse that surprises everyone. Of course, the OPCE has endless traps to beat him and George…

At first, Mantaro Ohara was just an ordinary salaryman with slightly bigger appetite. For Mantaro, eating is something to be enjoyed and the idea of food battle does not sound attractive to him. But his meeting in Pork Cutlet store with the professional competitive eater, George Hunter, gradually changed his view and passion towards gourmet competition... And they probably would not let this unexpected "dark horse" escape either.

Mantaro heard about curry udon eating contest in Nagoya and went straight to win 100,000 yen prize. He met again with Torikai, another female rival, Madame Morning, and the familiar face that he had always despised…

Although Mantaro had tried to bring Torikai back to TPCE, he lit a new rivalry flame between them instead. Calmly going back to his training, this time Mantaro faces a dorayaki-eating battle...

After the boiled eggs eating battle between Thomas and Nikolai, it is now the turn for two members from the Five Stomach Starts to face each other--Can Dahu and Yang fight without caring about their past?
