The February issue of Kadokawa Shoten's Monthly Gundam Ace magazine is announcing on Saturday that Mayu Shinjo is launching her Kidō Senshi Gundam Zeon Kōkoku Yōnen Gakkō (Mobile Suit Gundam: The Principality of Zeon Children's Academy) in the March issue in January.

The manga is set in the seceding space colonies during the year Universal Century 0079 — the timeframe of the One Year War from the first Gundam space anime series. The story follows five boys who all share a sense of "camaraderie, duty, … jealousy, and war."

Shinjo, the manga creator of Sensual Phrase (Kaikan Phrase) and Love Celeb, had revealed in an August blog entry that she will launch a new series in Monthly Gundam Ace magazine in November. However, the manga has since been delayed until January. She already launched a new romance manga called Heart no Diamond in Shueisha's Ribon magazine in July. Shinjo has been writing and illustrating her own columns for Monthly Gundam Ace and Seed Club Mobile, the mobile version of the official Mobile Suit Gundam Seed club.

After a much-publicized exit from Shogakukan's Shoujo Comic magazine in 2007, Shinjo has been drawing her Ai-Ore! Danshikō no Hime to Joshikō no Ōji manga in Kadokawa Shoten's Monthly Asuka magazine. Viz Media published Sensual Phrase in North America.
