|This article is about a/an episode in Samurai Sentai Shinkenger.|
As the other Shinkenger relax, Takeru trains in increasing his Mojikara in order to use a beetle-themed Secret Disk, which becomes necessary against an Ayakashi their swords can't cut.
While the vassals spend their leisure time at an amusement park, Takeru trains to master the use of the Kabuto Secret Disk by making his Mojikara twice as strong. While he attempts this, the vassals attack the Ayakashi Yanasudare whose attacks have no effect on his flexible body and are no match for his marksmanship. Once Shinken Red arrives, the Shinkengers are no match for Yanasudare who falls back when he begins to dry up. While at the Shiba House, Jii instills hope in the vassals as Takeru reveals the Kabuto Disk to them and it may be the key to defeat the Ayakashi once he masters doubling his Mojikara. Takeru keeps training into the night, nearly destroying himself with Jii watching with worry. The next day, a rehydrated Yanasudare resumes his attack with the vassals arriving to fight him as Takeru arrives to challenge him. Though reluctant at first, Takeru channels enough Mojikara to use the Kabuto Disk, allowing his Rekka Daizantou to assume Ōzutsu Mode in order to fire the Kabuto Five Rings Bullet to kill Yanasudare. When Yanasudare resurrects into a giant, he overwhelms Shinkenoh until Shinken Red uses the Kabuto Disk to summon the Kabuto Origami. To counter the Ōnanashi Yanasudare summons, Kabuto-Shinkenoh is formed to take them out before slaying Yanasudare. After the fight, a nearly exhausted Takeru returns home as Jii helps him up.
