Episode 1: The Mashin Are Born! (魔進誕生！ Mashin Tanjō!) is the first episode of Mashin Sentai Kiramager. It features the debut of the Mashin and Juru's full debut as Kiramei Red.
A once peaceful day has now suddenly been lost. The Army of Darkness, Yodonheim, have buried the crystal kingdom of Crystalia into deep darkness, and have set their sights on an invasion of Earth. Descending from the sky comes a fearsome creature known as a Jaguchihirudon who destroys the city alongside several Bechat foot-soldiers on the ground, plunging the city into a massive panic. However, there is no need to fear, for there are heroes on Earth who can save everyone from this unprecedented crisis! The Kiramagers, four warriors with shining spirits, who were granted the power of the Kiramai Stones from the fallen kingdom of Crystalia to fight against the Yodonheim Army. Meanwhile, the princess of Crystalia, Mabushina, searches for a fifth warrior whose spirit resonates with the last Kiramai Stone. It was just then when she noticed an ordinary high schooler by the name of Juru Atsuta, who would always continue to draw even in the midst of a calamity.
