Snake Joe is awakened from a sound sleep of Creamy Mami having perverted his subterfuge to his detriment once too often by Kumiko who exhorts his assistance in the synthesis of okonkomiyaki; after giving the matter some thought, Snake Joe reconsiders as he sets in motion a bid to have his revenge by attacking the Morisawa family economy. Tetsuo and Natsume have quite the imbrogilo on their hands: they do not realize Yuu has been leading a double life as Creamy Mami right under their noses; still, not yielding this data to Snake Joe will scuttle their economy. Realizing that Snake Joe will at best break even with his incumbent tactics as he washes the van alongside Mamoru who explains Kumiko's commercial prologue in Osaka, Tetsuo decides to hold a contest while Snake Joe approaches Creamy Mami with a contest challenge of his own: whichever of the two businesses Creamy Crepes or Okonkomiyari Car of Fire sells the most in a week wins. During the calendar week of the competition, both businesses employ various tactics fair and foul to build their clientele base at whose acme is Kumiko availing her father's friends from Osaka in the Car's favor; the ultimate irony is that it is Kumiko's father and his friends that also forces Snake Joe to resolve the aftermath of his earlier subterfuge.
