Twelfth Lesson - Zowan-Zowan! Confrontation Beast-Fist, Training Starts (修行その１２ ゾワンゾワン！臨獣拳、修行開始, Shugyō Sono Jūni: Zowan-Zowan! Rinjūken, Shugyō Kaishi) is the twelfth episode of Juken Sentai Gekiranger. It focuses on Rio's training with Sky Fist Demon Kata and gives further background of the past of RinJyuKen's leader.
Rio undertakes training with Kenma Kata by reliving his greatest moment of despair, while the Gekiranger go to a bathhouse to deal with a slippery Beast-Man.
While wandering through the city, Jan finds Natsume at a bathhouse looking at the carp windsocks. When the bathhouse's owner Gen-san confronts Jan when he is trying to take down one of the windsocks, Natsume is accidentally sent flying towards the street as a result of Rin Jū Eel-Ken user Nagiu's Ringi. The Gekirangers try to fight, but he is too slippery to be hit by their attacks. Xia Fu sends the trio to train at the bathhouse, where they re-encounter Elehung and Gen-san who is revealed to be a master of "towel-style." Jan learns how to use the "towel-style" and in the next fight with Nagiu, Jan uses one of the carp windsocks to dry the Beast-Man of the slippery mucus, followed by the Geki Bazooka. Nagiu soon grows to his giant size, and the Gekirangers fight first as Geki Tohja and then Geki ElephanTohja. Nagiu is ultimately defeated by the Great Firm-Firm Ball of Geki ElephanTohja.
Elsewhere, Rio was trying to learn how to attain ultimate power from Kata in a battle to the death, and in the process is blasted by the Hawk-Ken master's Darkness Cannon and is placed within the event of his past that started his path in becoming a Rin Jūken user. Rio was able to absorb his own despair and breaks Kata's illusion, sparing Kata for enabling him to become stronger. By being beaten, Kata accepted Rio as a pupil to learn the full power of Rin Jūken Akugata.
