あだち充
is a Japanese manga series written and illustrated by Mitsuru Adachi. The series ran in Shogakukan's "Weekly Shōnen Sunday" from January 1990 to April 1992. The story is set in a place very similar in appearance to Earth in the Edo period. However, Adachi regularly reminds the reader all throughout the series that the setting is another planet in the distant future which just happens to look like Earth.
