Description
Retsu Seiba (星馬烈) is the 11-year-old elder brother of Go Seiba, standing 124 cm tall and weighing 28 kg. Born April 10 with blood type A, his distinctive appearance features bright red hair, matching red eyes, and a signature green hat always worn with red-themed clothing and gloves.
Patient and level-headed, Retsu contrasts Go's impulsiveness. He analyzes track conditions and opponent strategies mid-race, though he occasionally shows irritation toward provocateurs. A firm believer in fair competition, he rejects underhanded tactics or destructive weaponry. His kindhearted nature prioritizes team success over individual accolades.
Specializing in cornering stability, Retsu pilots Sonic-series Mini 4WD cars designed for balanced handling. He personally created the red-and-green color scheme for his first pro car, Sonic Saber, destroyed at Dr. Ogami's volcanic lab. Later machines include Vanguard Sonic, Hurricane Sonic, Buster Sonic, Blitzer Sonic, Great BlastSonic, and CosmoSonic. His development tactics involve strategic deception, like feigning interest in battle machines to enhance Hurricane Sonic without adopting destructive methods.
Retsu's racing journey begins locally with the Super Astute Jr. before receiving Sonic Saber from Dr. Tsuchiya for national and international competitions. As captain of Japan's TRF Victorys team during the World Grand Prix, he champions formation racing and team coordination over Go's solo style. Years later in *Return Racers*, he works as a space development engineer, contributing projects that include a probe named after one of his Mini 4WD cars.
His evolving rivalry with Go matures into a complementary partnership, earning them the "Let's Go Brothers" moniker—a play on Retsu's name. As TRF Victorys captain, he mentors teammates like J, Tokichi Mikuni, and Ryo Takaba. He clashes with Ogami Corps' battle racers but steadfastly opposes car-destroying tactics.
Beyond racing, Retsu collects postcards and enjoys video games. A justified fear of ghosts surfaces during one eerie episode. His adult engineering career applies technical skills refined through Mini 4WD customization.
