Geki 19 and 20.
Or, the Gekirangers lose so badly it looks like you're watching a fighting game combo video.
I love it. Rio forcing the fights to be one on one through the help of two beetle warrior armor things also helps. It really cements in the fact that Geki works best as a triangle. As strong as our heroes get, they need each other to support one another.
Anyway, they all lose, but Jan shows some potential the achieve Kageki, the one thing Rio never could, so Xia Fu is taken prisoner and they're given 3 days to do it.

In comes 3 more Kensei, Gorri, Michelle, and Pyon Pyon. They train the Gekirangers in their weakest areas (Jan has Heart, Ran has Technique, and Retsu has Body), in a 3 part tournament. Jan's impatience causes him to lose to Gorri, but Ran's dedication and support helps her tie with Michelle, while Retsu's dedication allows him to beat Pyon.
(By the by, if this was any other show, Retsu's showdown with Pyon would've been given to the red ranger)
This allows them to grow in their weakest area to further their ability to becoming a perfect triangle (Even Jan, who lost, managed to keep a cool head and learn from his mistake, helping him grow his heart)

I like this. You can see aspects of this in their special weapons (Ran's Geki Hammer is easily Body, Retsu having to clear his mind in order to use the Fan is basically him fighting with his Heart, and while Jan's Geki Sabers are dubiously Technique, for how they're designed (Flimsy and thin), it's more than just hitting really hard when it comes to handling them, so there is some technique to it), so for them to further train in another aspect is great.

Love it~
