Netsu-Netsu! Forget the Technique is the fourteenth episode of Juken Sentai Gekiranger.
Synopsis
Ran and Jyan arrive to fight the Flying-Ken, who overpower them until Rasuka is offended by them and has Rūtsu fly off while he beats the two Gekirangers by himself, wounding Ran's leg. While Ran is being tended to, Miki brings out the new weapon for Retu and tells Jyan and Ran to give it to him once he has completed his training. This training, in his eyes, is attempting to dance just like Bat Li. He initially has trouble, but he eventually realizes that Bat Li's dancing has no technique. Once Jyan and Ran find Retu and Bat Li, Retu has mastered the Bat-Ken style while in a trance, and he is given the Geki Fan. With the Geki Fan, Geki Blue defeats the Flying-Ken singlehandedly. The Flying-Ken enlarge themselves and are able to unleash their attack, but on Bat Li's words, the Gekirangers enter a trance to bring out legendary Geki Beast Geki Bat, with whom Geki Tohja combines to form Geki BatTohja to battle the Flying-Ken in an aerial dogfight. The fight ends with Rūtsu slamming into the side of a mountain and Rasuka destroyed. Meanwhile, after surviving Kata's training to channel his hatred, a bloodthirsty, berserk Rio attacks the Rinshīs with rage to amplify his malice even more until Rio's hatred became new Rinki, to Mere's horror. That same hatred awakened Rūtsu as he emerges out of the rubble of the battlefield with intend on getting revenge on the Gekirangers for the death of his partner.
