Daishi Morimiya is a high school student whose dream is to become a wheelchair, track-and-field athlete. In addition to that, Miyako Fukai, a former wheelchair athlete, becomes Daishi’s coach. One day, a handsome alien falls from the sky when Daishi was practicing with Miyako, surrounded by his friends and father (who is employed at an old factory). The handsome alien named Goo, after escaping a mass genocide somewhere in Earth’s binary star, warns Daishi and his friends that Earth is in danger. Then, a giant lizard-like monster who is after Goo, attacks Daishi’s household. That’s when Goo’s Mode Shifter begins to emit light, radiating Daishi. His body is completely transformed by a special protector. The transformed Daishi charges at the monster while still in his wheelchair.

Taishi Morimiya (So Okuno) suffers from the weight of his mission while continuing to practice wheelchair track and field with coach Kyo Fukai (Fuka Koshiba). On the other hand, Rio Seino (Mori Nakamura), who can understand the intention of Goo (Hayashi Karasu) for some reason, finds out that he has escaped from the massacre on the alert star. Laru (Miki Mizuno) and the monster Lagert appear there in an attempt to abuse Goo's abilities, and Kyo is captured. Gandine sorties on a high-performance wheelchair made by his father, Takeshi Tsuruno, and his factory colleagues!
