ナンバー7 [Number 7]

A short-lived but distinctive science-fiction series from the mid-1970s, Number 7 ran for just four issues under Shueisha's imprint. The series is most associated with its creator, who crafted a self-contained story of a mysterious protagonist with a barcode on his forehead, blending espionage and futuristic themes. Despite its brief run, it remains a notable artifact of its era, showcasing the experimental edge of Japanese comics at the time.
