Tai Chi Chasers Episode 8. Opposite Day!

Rai is jealous of Finn's superior performance in the field. He ignores Finn's advice during combat and attempts to use a Tai Chi card against the Dragonoids. However, Rai is unable to properly use the artifact due to his lack of experience, which leads to Tori being captured by the Dragonoids as a prisoner of war. Later, Finn puts himself in a vulnerable position in order to distract the Dragonoids so that Rai can successfully rescue Tori from the enemy. In the end, Rai recognises Finn's altruistic qualities and reconciles with him, although Rai still resolves to eventually surpass his abilities.
