Kanto's warrior schools face a devastating threat. Mysterious fighters from Nara have stripped away the Magatama jewels of two of their strongest leaders, leaving Gentoku Ryuubi as the only fully operational commander standing against the assault. The attackers answer to Himiko and the dangerous Yamato School. With their backs against the wall, the fighters of Nanyo, Kyosho, and Seito band together to strike back. It's a desperate gamble. They suspect they're walking into a clever trap, but they see no other choice. Even Hakufu Sonsaku, stripped of her own jewel, insists on joining the fight. Getting to Nara proves more complicated than expected when Hakufu is left behind at a station along the way. Waiting at Yamato Gakuin are Kansai fighters under the influence of Himiko's curse, while Chouhi, still in the middle of her training, senses that Ryuubi is in danger. The result is an action comedy with a heavy dose of ecchi fan service.
