Marlin Fishing (舵木一本釣 Kajiki Ippontsuri) is the seventh episode of Samurai Sentai Shinkenger.
Ryunosuke is sent to catch the Marlin Origami living in the wild, where he must work with a jaded fisherman to save his team from a poisonous Ayakashi.
While having breakfast, the Shinkengers learn that the Kajiki Origami has been sighted at the Funabuta Coast as the Ayakashi Yamiororo appears. While the others go after Yamiororo, Ryunosuke is sent to acquire the Origami itself by fishing for it. But after failed attempts to catch it, Ryunosuke receives the aid of a mysterious fisherman named Sakutaro Komatsu before being contacted by Jii that the others got poisoned by Yamiororo and the Kajiki Origami is needed to cure them. Though Sakutaro questions the point of his endeavor, Ryunosuke resumes fishing as Takeru leaves to slow Yamiororo down in spite of the pain from the poison. Motivated by his lord's determination, Ryunosuke finally manages to fish the Kajiki Origami out with aid from Sakutaro. With the Kajiki Disk in hand, Ryunosuke makes his way to Takeru as the other vassals came to his aid, using the disk's power to cure everyone before they change to use the Rekka Daizantou's Kajiki Five Rings Bullet to kill Yamiororo, destroying him again with the newly formed Kajiki-Shinkenoh. As Sakutaro secretly resumes his duty as a kuroko, a mysterious figure who witnessed the Shinkengers' fight with Yamiororo walks off.
