くたばれ！！涙くん[Kutabare Namidakun] [Go do it! It is! Tears]

A short-lived but emotionally charged series from Akita Shoten, "Kutabare!! Namidakun" ran for eight issues between 1970 and 1978, a period that saw the rise of more introspective manga. Written and illustrated entirely by Isami Ishii, the series explores themes of resilience and sorrow through its title, which roughly translates to "Go to hell, Tears!"—a bold, defiant cry against despair. Despite its brief run, it stands as a distinctive, creator-driven work in Ishii's career, offering a raw, personal touch that resonates with fans of vintage Japanese comics.
