Act 1: The Gallant Appearance of the Five Samurai

The Gallant Appearance of the Five Samurai is the first episode of Samurai Sentai Shinkenger.

Synopsis
Takeru Shiba, the 18th head of the Shiba Clan, must gather together his four retainers to become Shinkenger to face against the return of the Gedoushu and their leader, Dokoku Chimatsuri.

Plot
When the Gedoushu are revived and begin to attack the mortal realm, Takeru Shiba of the Shiba House takes arms to fight them as Shinken Red. After defeating a company of Nanashi, Takeru becomes annoyed when his retainer, Hikoma Kusakabe, affectionately called "Jii", implores him to find his four vassals to fight alongside him, instead of fighting on his own.

Meanwhile, on the Sanzu River, Doukoku finally awakens, and upon learning that the Shinkengers still exist, becomes enraged and sends the Akayashi Kagekamuro to attack the humans with an army of Nanashi. Against Takeru's wishes, Jii summons the vassals: kabuki actor Ryunosuke Ikenami, kindergarten teacher Mako Shiraishi, carefree Chiaki Tani, and pure-hearted Kotoha Hanaori. Upon meeting the four, Takeru gives each one a chance to back out of his service, and when all four of them decline, he gives each one a ShodoPhone. Takeru, Ryunosuke, Chiaki, Mako, and Kotoha then take on Kagekamuro and his numerous Nanashi. Shinken Red slays Kagekamuro, but in spite of that, he tells his vassals to remain on their guard. Sure enough, the Ayakashi is reborn as a giant, so the Shinkengers enlarge their Origami to confront and destroy him. After the battle, Jii arrives to bring everyone to the Shiba House.

Trivia

 * Key Title Kanji: 侍 (Samurai)
 * Ryuunosuke's misassumption that the head of the Shiba Clan was female when first attempting to meet Takeru (in actuality Mako) could be a subtle hint of the real Shiba head.
