1 ★2作戦 [One.Two Sakusen][1 ★ 2 Strategy]

In this short-lived 1969–1970 series from Akita Shoten, writer-artist 貝塚ひろし (Hiroshi Kaizuka) crafts a brisk, standalone espionage thriller centered on a covert strategy dubbed "One-Two Sakusen." Spanning just three issues, the comic delivers a tightly wound tale of undercover operations and tactical intrigue, showcasing Kaizuka's distinctive manga style during the late 1960s. Though brief, it stands as a compact example of the era's genre storytelling.
