Kazuma Failed!? Ultra C to the Rescue!
Kazuma was initially disqualified along with other 13 people who chose the same butter as him (i.e.: butter C, revealed to be margarine) by Kuroyanagi, however Kazuma was re-admitted into the Newcomers' battle after Kuroyanagi tasted his butter rolls. This episode also introduces Mizuno Azusagawa, Tsukino's younger and bratty sister, along with the animosity between the two sisters. Near the end, after Kazuma and Kyosuke learned about the issue between the Azusagawa sisters from their manager, they decided to give their best to win the Newcomers' battle to support Tsukino. Mizuno also sets up a gamble in which if Kazuma loses to her, he will have to transfer to Mizuno's new Tokyo Pantasia branch, however should Kazuma wins, Mizuno has to begin respecting Tsukino as her older sister.
Aired 28/12/2004EP 12 - Kazuma Failed!? Ultra C to the Rescue!

Yakitate!! Japan
Kazuma Azuma wants to make bread. Not just any kind of bread, though. He wants to make a bread that represents Japan itself and can stand toe-to-toe with rice as a national food. Thanks to his legendary "Hands of the Sun," unnaturally warm hands that allow dough to ferment faster, Kazuma's bread is like a slice of Heaven.
And when the Pantasia Rookie Competition arrives, everyone will get a taste of his skill! Along with his friend Kawachi (who's only in it for the dough), he’ll go up against koala karate masters, Harvard bread scientists, samurai with rolling-pin swords, and more! Can Kazuma create bread like naan other and bake his way to glory, or should he quit before he's toast?
