Description
Dan Amo is a 27-year-old salaryman working in the General Affairs department of the Hyuga Corporation, born in 1990 during the Year of the Horse. He stands 175 cm tall, weighs 68 kg, and has blood type B. By day, he presents an ordinary office worker facade, but by night he rides his Yamaha MT-09 Street Rally/Tracer through Tokyo, displaying exceptional natural talent that earned him the nickname "Zebra" among riders on Route 246. His hobbies include playing the piano and computer graphics.

He resides with his aunt Sanae, owner of the Genesis Café in Aoyama, where he stores his motorcycle. After work, he often eats at the café before embarking on nighttime rides to escape corporate monotony. His instinctive riding skills allow him to outmaneuver pursuers, including Kotaro Hyuga—heir to the Hyuga Corporation presidency—who tests powered suits against Dan.

Dan carries unresolved childhood trauma linked to his parents' fates: his father died in an incident involving Hyuga's Marishi Machina powered suit development, and his mother was placed in cold-sleep during related experiments. He initially avoids confronting this past, but freelance journalist Makina Mikage encourages him to seek the truth. This quest leads him to Hyuga's secret Mt. Fuji testing facility after Chairman Mitsukuni Hyuga reveals his mother may survive. Accompanied by Makina—who seeks her own missing father—Dan participates in a dangerous reenactment of the original Marishi Machina test to revive his mother and uncover the truth behind the incident.

This journey forces him to confront his trauma and his parents' legacy directly. He intervenes when the Marishi Machina suit seizes control of Makina's unconscious body, chasing her on his motorcycle to prevent disaster. This deepens his entanglement with Makina and Kotaro, intertwining their fates through corporate secrets and personal redemption. A year after the Mt. Fuji events, Dan embarks on a solo touring trip, signaling his ongoing evolution beyond his traumatic past.
