Ryunosuke, Chiaki, and Kotoha are forced to observe the Kuroko for a day to understand their job for the Shiba Clan and the city.
Some time after the working on their Mojikara training, on Jii's suggestion after causing a priceless vase to break, Ryunosuke, Chiaki, and Kotoha become curious about the kurokos' helpful nature as Takeru reveals they even help everyone in the city. Inspired, Ryunosuke, Chiaki, and Kotoha attempt to be of help to the community, only causing trouble with a kuroko outdoing them at every time. Chiaki, Ryunosuke and Kotoha try helping a lost girl. But as a result, Chiaki and Ryunosuke scare her. Kotoha tries and she tells a officer. The officer thinks Kotoha is lost. But their intent to help others hampers their abilities when they go up against the shy Ayakashi Marigomori before he runs off. After talking to the three that the kuroko also support them by ensuring they can fight without any one getting in the cross fire, the Shinkengers respond to Marigomori resuming his attack. Using a combination of Mojikara element attacks, the Shinkengers weaken Marigomori's shell before destroying him with the Tora Five Rings Bullet as the kuroko cheer them on. When Marigomori is resurrected, Shinkenoh uses the Kabuto and the Kajiki Origami to re-weaken the Ayakashi's shell for the Tora-Shinkenoh to finish him off. Later, the gang watch the kuroko working hard as one of them gets on Jii's bad side for breaking a priceless heirloom.
