勧善掌悪始末人 [Kanzen Shouaku Shimatsunin]

A single-issue comic from 1985, 勧善掌悪始末人 (roughly translating to "The Handler of Rewarding Good and Punishing Evil") was published by 白泉社 (Hakusensha). Its premise centers on a vigilante who dispenses rough justice, though the series ended almost as soon as it began, leaving this lone issue as a curious, self-contained artifact of mid-80s manga.
