Naeka's friends, Eiko and Miwa, ask Kogarashi to bake cake for the cake shop they work in, since their depressed cook can't cook anymore. Eiko and Miwa also ask Naeka and Fubuki, who have D-cup breasts, to infiltrate their cake shop's rival shop, which has terrible cakes, but all waitresses have huge D-cup breasts. Fubuki, not wanting to wear the shop's revealing uniform, flees and tries to hide from Naeka.
