The Raimon Eleven return to Raimon Junior High only to find Ryūichi Kenzaki waiting for them there, along with Raimon's old members who left the team due to injuries.

But each one of Dark Emperors has increased their abilities even more than Raimon has imagined. How will they fight against their friends now?
