The magazine contained manga series and manga short stories as well as commentaries and manga criticism. Similarly to
Garo having
Shirato Sanpei's series
Kamui as a pillar for the magazine,
COM published two longer series by major artists,
Phoenix by Osamu Tezuka and
Jun by
Shotaro Ishinomori. Also a few chapters of Ishinomori's successful series
Cyborg 009 were released in
COM. Regular contributors included people from Tezuka's circle of disciples around the residential building
Tokiwa-sō such as
Jirō Tsunoda,
Hideko Mizuno,
Fujio Akatsuka and
Fujiko Fujio. The series
Tokiwa-sō Monogatari, published from 1969 until 1970, recounted the life at Tokiwa-sō, with each chapter being written by a different manga artist. Other regular contributors were
Leiji Matsumoto,
Hisashi Sakaguchi and
Shinji Nagashima.
COM was also an attempt of Tezuka's to boost young talent by motivating readers to submit amateur work to the magazine's amateur section
Grand Companion, or short "Gurakon", and by creating amateur manga clubs, zines and self-published manga locally around Japan. This was inspired by the approach of the magazine
Manga Shōnen, which was published from 1947 until 1955 and was the career start of several influential manga artists. Shotaro Ishinomori had made his debut in this magazine and Tezuka had published Phoenix for the first time in
Manga Shōnen. The magazine made a conscious effort to have cross-gender appeal. While the founder and most editors were men, the magazine had many regular female contributors such as
Masako Yashiro and
Minori Kimura and was instrumental in giving women space for experimenting with narrative and form outside of the conventional norms of
shōjo manga. in particular, who had been rejected by
Garo and made her debut in
COM, with her abstract visuals, references to European art history and mix of poetry and comic inspired other women to submit manga to the magazine. == Legacy ==
