|This article is about a/an episode in Samurai Sentai Shinkenger.|
With the sudden increase in Gedoushu power, the Shinkenger head to Tengen Temple to obtain a sealed case which may assist them, while Shitari attempts to find out the sealing character that stopped Doukoku in the past.
As Doukoku attempts to gain control of his summer-induced power boost, a legion of Ōnanashi attack with Tenku-Shinkenoh and Ika-Daikaioh destroying them off as the Sanzu River begins to flood into the mortal realm. With the Gedoushu becoming stronger during the summer, Jii reveals that the Shinkengers need the Inromaru to counter the increasing threat. Arriving at the Tengen Temple, the burial grounds of the Shiba House, the Shinkengers are given the Inromaru after Takeru visited the tombtone of his father. While the Shinkegers have tea, the rogue Ayakashi Gozunagumo makes his move as Takeru has been poisoned by Shitari. While the vassals are overpowered by Gozunagumo, Shitari appears and offers Takeru the antidote if he tells him the sealing character so Gozunagumo can use it on Doukoku. After attempting to get Juzo to sample his sushi, Genta arrives and fights Shitari and loses to him. At the last second, Juzo arrives and takes Takeru while exposing himself to Genta. Back on the Rokumon Junk, Doukoku awakens and drags Gozunagumo back to the boat as he punishes the Ayakashi for acting behind his back by infusing him with some of his new-found power.
