風車の教室 [Fuusha no Kyoushitsu]

A single-issue series from Hakusensha, 風車の教室 (Windmill Classroom) was published in 1975. As a one-shot, it stands as a self-contained work from that era, offering a brief but complete story. Its significance lies in its status as a singular, early entry in the publisher's catalog, a snapshot of the manga landscape of the mid-1970s.
