Act 21: The Father and Son Bears

The Father and Son Bears is the twenty-first episode of Samurai Sentai Shinkenger.

Synopsis
In the midst of other problems, Chiaki must save Mako and others from a hostage crisis as ShinkenPink discovers more about his personal style through Chiaki's father.

Plot
The Shinkengers battle a group of Nanashi Company with no accompanying Ayakashi sent out by a strange warrior. Because the attack seems so random, Takeru is concerned and has the Shinkengers search the area. An unusual Kuroko lifts his veil as the Shinkengers leave the scene.

After searching and not finding anything, Chiaki talks Mako into not returning to the mansion to train. Instead, they go into a family restaurant where they talk about Jii's hip until they run into Chiaki's father Kurando Tani. When another patron of the restaurant takes a woman as his hostage, Chiaki manages to get everyone out with him but Mako, Kurando, and a mother with her baby. Finding similar humans, Chiaki attempts to stop them as he realizes they all have red eggs on their heads. While the others deal with the Ayakashi Sasamatage who is to blame, Chiaki and Mako manage to set up a plan to free everyone while Kurando fights some Nanashi Company members by himself. By the time they arrive, the other Shinkengers successfully destroy Sasamatage who revives in his giant form. The group use Tenku-Shinkenoh to fight Sasamatage with Shinken Gold arriving in Daikaioh to quickly destroy the Ayakashi as a young woman witnesses the battle.

After the fight, Takeru encounters a strange man who warns him of that his world is endangered by the presence of a person known as Decade. He later crosses paths with a strange kuroko who reveals his true identity.
