Akita Oga is an 11-year-old pilot for the Shinkansen Ultra Evolution Institute’s Ōmiya Branch, hailing from Akita Prefecture. He comes from a family of traditional matagi hunters, which has given him exceptional riflery skills and deep wilderness knowledge. Recruited after placing second in a synchronization aptitude test, he pilots the E6 Komachi, a red, oni-themed Shinkalion specializing in long-range precision attacks using firearms and shoot-and-scoot tactics, with rollerblade-style wheels and targeting-goggle forehead crests. Personality-wise, Akita is quiet, calm, and reserved, contrasting with more excitable teammates, yet he has a secret enthusiasm for sweets and often carries candy, even showing familiarity with foreign chocolates. He tends to speak in a Tōhoku dialect around close friend Shinobu Tsukiyama, reflecting their shared regional roots. In the film Mirai kara Kita Shinsoku no ALFA-X, he participates in the collective defense against the extraterrestrial invaders Nahane and Ohanefu, operating the E6 Komachi in ranged support against Giant Monstrous Beings. His surname Oga references the Oga Line or Oga Station, while his given name Akita comes from the Akita Shinkansen Line. Visually, he has purple hair and eyes, typically styled spiked with a distinctive streak, and wears a red pilot suit with white sections, black arrows, and specialized headphones featuring glowing red lines.
