The Great Sky Combination (大天空合体 Daitenkū Gattai) is the tenth episode of Samurai Sentai Shinkenger.
Chiaki and Hikoma reach their breaking point and must come to a new understanding after Shinken Green is passed over to assist in creating Daitenkuu, a new Origami formation.
After Takeru reveals to his vassals that the three support Origami can be combined into DaiTenku, the Kabuto Disk is entrusted to Mako as the Kabuto Origami's official user to the dismay of Chiaki, who feels he is lacking and proceeds to train himself. When the Ayakashi Okakurage arrives and uses his power to conjure despair-inducing rain, the Shinkengers arrive to fight him. During the fight, Shinken Green attempts to use the Kabuto Disk to fight, only to be unable to use its power as Okakurage escapes. Soon after, an irate Jii chews out Chiaki as the two start to argue while the other vassals attempt to stop the fight. Later, after talking to Takeru of his actions, Jii takes Chiaki to a bamboo forest to explain the true nature of Mojikara and must embrace his character to access its full power. By the time the two apologize to each other, Chiaki runs to his team's aid when they are overwhelmed by Okakurage. Mastering his Mojikara, Shinken Green manages to kill Okakurage as the revived Ayakashi proceeds to overpower Shinkenoh. After Shinken Pink gives Shinken Green the Kabuto Disk, the three male Shinkengers summon the support Origami and combine them all into DaiTenku. With Shinkenoh providing back up, DaiTenku manages to destroy Okakurage. Soon after, in spite of coming to terms, Chiaki and Jii get into another fight.
