I kinda hate these types of comics. There really isn’t any reason why this should be a comic other than the writer’s medium of choice. The message gains nothing from the visual aspect. The comic could really have been improved if the author showed what the characters are talking about, but we just get a wall of text with a crudely drawn woman to represent the opposition. Also, the art has no appeal and is generally ugly.
It’s a shame that they aren’t more popular; I didn’t really see prefectural flags flown that much outside of government buildings when I lived in Japan.
