The Hill Dyed Rose Madder

A Steel Festival

It's the school Cultural Festival and Yuuhi, Karen, Fuyuhiko and Tsukasa (along with the rest of their classmates) are doing a Yakisoba café. However, they face tough competition from the Yakisoba stand put up by Minato and the tennis club. Meanwhile Jun'ichi is kidnapped by Mitsuki, Nagomi and Mr. Sugishita for secret training regarding a dangerous mission. Back at the Yakisoba café the girls end up wearing their school swimsuits to attract business and end up triumphing over the tennis club's Yakisoba stand. At the end of the festival everyone is called out to the school track field to witness Jun'ichi's epic battle in his "Big Genokiller" against a robotic octopus.
