Soma recklessly challenges Shinomiya to a Shokugeki in order to have him retract his decision to expel Megumi. Shinomiya refuses, but Dojima half forces him to accept. However, Dojima also imposes a condition on Soma and Megumi--Megumi must be the main chef! If they lose, Soma will also be expelled. The unofficial Shokougeki is about to begin!
