It is a sister magazine to Big Comic, the biggest difference being that it goes on sale twice a month in the weeks Big Comic does not. Cover artwork usually features a dog or cat, and a haiku. The dozen or so manga serials running at any given time feature a wide variety of material, from historical dramas and suspense to sports and romance, with relatively little science fiction or fantasy.
