An Extermination Skill Contest

The vassals train as Chiaki is being chewed out by Takeru for over sleeping and his lack of training as a Shinkenger. This does not sit well with Chiaki, and he ditches training to go hang out with his friends Masato and Kouji. While they're out, they are attacked by the Ayakashi Rokuroneri as Chiaki runs at the monster. However, due to his lack of training, Shinken Green is easily defeated by Rokuroneri and his extending arms prior to his friends being attacked before the others arrives to cover their escape. Telling Chiaki that he is to blame for his friends ending up in the hospital, Takeru tells him he should quit if he cannot find a means to counter Rokuroneri's talent by the next day. After giving it thought, Chiaki gets an idea and starts to train himself as Takeru undergoes his own training. The next day, Rokuroneri resumes his attack until the Shinkengers arrive with Chiaki following to take on the Ayakashi on his own while the others deal with the Nanashi.With his training, Shinken Green manages to uses Rokuroneri's arrogance against him to disable his arms and execute the deathblow. When Rokuroneri is revived, despite Shinken Green's intent to finish him off himself, Shinken-Oh is formed and slays the Ayakashi after Shinken Red's own training pull off. After the fight, Chiaki finally accepts being Takeru's vassal and vows to surpass him in skill.
