My-Otome (舞-乙HiME, Mai-Otome?) is the manga counterpart to Sunrise's My-Otome series, following a storyline different from that of the anime. It is authored by Hajime Yatate (original creator), Tatsuhito Higuchi (scenario), Hiroyuki Yoshino (scenario) and Kenetsu Satō (art). During its 44-chapter run, it was published in Akita Shoten's Shōnen Champion, with its first publication in August 2005, two months prior to the release of the anime. Unlike what common sense might suggest, it is also apparently a semi-fusion of the Mai Hime anime and manga (e.g. Haruka's element and Shizuru's knowledge of her own naginata-wielding 'dark twin' as well as Alyssa's sisterly relationship with Natsuki Kruger and the apparent romantic relationship between Viola and the latter).
In addition, there is a derivative chapter called Mai Otome Super H, centred on an onsen visit. It was published in the Champion RED magazine. As the title suggests, it has hentai content, although it is a canonical work by the original mangaka and the content is not as explicit as most H-Doujinshi. It takes place between chapter 12 and 13, but no mention is made of it in the main plot.
It is unconnected to the new My-Otome Zwei manga, which follows the anime's plot more closely.
A continuation of the original manga was released called My-Otome Arashi which introduces Archduke Nagi's younger twin sister (disguised as a man) Arashi who has purchased Garderobe and all of its students after the campus incurred repair debts from the end of the original manga during Sergay's coup turning the school into a nightclub despite the fact that Garderobe is the single most vital element to all the nations of Earl by supplying Otomes (they have supposedly been abandoned by the world).
