さよならはっか糖 [Sayonara Hakka Tou]

A single, self-contained comic from Hakusensha, Sayonara Hakka Tou (1977) is a brief, poetic work from the early era of the publisher. Its title translates to "Goodbye, Mint Candy," and the issue stands as a quiet, singular piece of 1970s manga, notable for its standalone nature in an industry of serialized stories.
