Lesson 16: Jiri-Jiri! Confrontation Beast Hall, Extracurricular Class

The revived Rageku arrives at the Rin Jū Hall to meet Rio. However, much to Kata's distaste, Rageku favors Mere more than Rio. When Mere refuses to prove herself by fighting Rio, Rageku poisons Rio as her way to start Rio on the path of suffering and to start Mere's training with a foe of her choosing. Rageku then attacks the city and easily defeats Geki Tohja, with Xia Fu's appearance leading to a revelation on the origins of the Seven Kensei and the Three Kenma as the first Jūken Masters, until they assumed their current forms and founded the two opposing schools before the Geki -Rin Rebellion that led to the Demons' defeat. Rageku then forces Mere to fight Xia Fu, immobilizing the Gekirangers to ensure no interference. In order to win, Mere uses Infinite Waves on herself to fight at full strength despite her own internal pain. Rio watches while the poison courses through him, until he overpowers Rageku's Ringi and save Mere from sacrificing herself to kill Xia Fu. After a brief fight, Rio defeats Rageku, though she reveals that she was only testing him for his jealousy of Mere being able to overwhelm Xia Fu. Rageku then took Rio and Mere as her disciples while as the Gekirangers start training harder.
