Eighth Lesson - Koto-Koto… Earnestly Koto-Koto (修行その８ コトコト…ひたすらコトコト, Shugyō Sono Hachi: Koto-Koto… Hitasura Koto-Koto) is the eighth episode of Juken Sentai Gekiranger. It is the fifth episode of the battle with the Five Venom Fists, concluding a two-episode showdown with both Sorisa and Maga and introduces the Gekirangers' team weapon, the Geki Bazooka.
With the combined defense of Maga and offense of Sorisa, the Gekirangers were overwhelmed. To counter the powerful tag-team, the Geki Bazooka needs to be used despite still being incomplete. However, to perform the Geki Waza Fierce-Fierce Cannon, it must be charged within two minutes, leaving the Gekirangers open to attack. Thus Jyan must train so he can hold off both two Venom-Ken at once while Ran and Retsu charge the weapon up with their Geki . But Jan's need not to be "Boko-Boko" (beaten up) resulted with the first try a bust. But as Xia Fu endures the pain of training Ran and Retsu himself, he has Natsume train Jan in the waiting department. When the Gekiranger encountered Maga and Sorisa once again, Jan was able to hold them off long enough for the Geki Bazooka to fully charge up. The Gekirangers used the new weapon to destroy Maga and later fought and destroyed the irate Sorisa with Geki Tohja's Great Spin-Spin Leg. Now only Rin Jū Snake-Ken user Braco of the Five Venom-Ken remains, and Rio's dreams are getting stronger by the minute to the snake's advantage.
