The Battle of Two Chef - S1.E22

Mao was chosen to hold the restaurant key. Then, when he had to leave the restaurant for some pick-me-ups, he left the restaurant to Meirii and Siro's care. Now, when Meirii was about to close the restaurant, Shel (even though his name isnt mentioned yet), demanded to be let in and ordered for some stir-fry veggies. Siro, thinking that he would be some help, decided to fry the stir-fry instead. Shel was outraged to taste such a disgusting dish and demanded for the cook. Mao immediately took responsibility and thus, Shel saw the cloth wrapped over Mao's 'Super' badge. Shel then showed Mao the stars he earned when defeating other good chefs and Mao is surprised (naturally).

Shel challenges Mao for a siu mai battle but Mao refuses as he has to take care of Yosen Shuuka. Shel, outraged, uses his stick to destroy the place. Ruoh and Choyu came back when Mao finally accepted the challenge and Meirii is doubtful about this. By that time, Shel had discovered that Mao is a 'Tokyu Jiushin' or Super chef.
