Goro-Goro! Teacher and Student Love is the seventeenth episode of Juken Sentai Gekiranger. It is the beginning of a two-part story which introduces the fourth Fist Sage of Geki Juken, Master Sharkie Chan, and focuses on his training of Jan.
The Gekiranger are left on an island where the fourth Fist Sage tests them, leading to Jan to encounter someone who fully understands his ways.
In order to combat Rageku, Xia Fu sends the team to the isolated Aozame Island to meet the Kensei Sharkie Chan, Grand Master of the Geki Jū Shark-Ken style. In a series of tests which comprised paddling a canoe through several traps, Sharkie becomes impressed by Jyan's strength and chooses him as his pupil for learning how to master his style and the Geki Sabers. In this training, Jyan becomes attached to his teacher, and they form a bond. Meanwhile, Rin Jū Hermit Crab-Ken user Dokariya closed in on the group's location, and uses his Ringi Base-Form Robbing Strike to take over Sharkie Chan to have him suffer as Rageku intended: By having him attack the Gekirangers. But Jyan's bond with Sharkie allows the Kensei to overpower Dokariya's Ringi, with an enraged Jyan using the Geki Sabers on the Beast-Man before the gang fires Geki Bazooka on him. When he becomes a giant, the Gekirangers call upon Geki Tohja and use Jyan's training to summon the Legendary Geki Beast, Geki Shark. They send Geki Shark at Dokariya, who is seemingly destroyed, only to be attacked by Geki Shark upon its return to everyone's shock.
