Higuchi Tatsuhito

One day while Shirou was delivering a secret weapon to his colleague, he met Amane Mao, a super strong girl who is capable of lifting cars. Before they knew it, an ERROR, a monster that struck Old Tokyo 14 years ago, reappeared and started on a rampage. While he was arguing with his colleague over the use of the super weapon to save civilians, his colleague was blown away and died. Faced with death, Shirou had no choice but to combine with Mao with the super weapon and destroy the ERROR.

Sequel to Mai-Otome. Set 3 months after the 1st series.

My-Otome Zwei takes place one year after the events of My-Otome. Arika is now a full-fledged Otome (though still under the tutelage of Miss Maria as she has yet received enough credits to graduate) and Nagi is incarcerated in a prison somewhere in Aries. The various nations are at peace with one another and plan to hold S.O.L.T. (Strategic Otome Limitation Talks) to discuss limiting the numbers of Otome. A mission to destroy a meteor threatening to collide with Earl sets into motion a chain of events which result in a mysterious shadowy figure attacking Garderobe and several Otome as well as a new, more powerful version of Slave appearing across the planet. To make matters worse, Queen Mashiro disappears following an argument with Arika. The series follows Arika's search for Mashiro as well as Garderobe's attempts to uncover the truth behind the shadowy figure.

Mashiro-hime has just transferred to the all-girls school, Garderobe…but little do the other students know, she's actually a boy. Desperate to escape an all-boys school where he was looked down upon, he disguised himself as the late Mashiro-hime to get in. Unfortunately, due to "her" royal status, members of an organization known as Shwarz are trying to assassinate him, and all the while, he's trying to break his Contract with Arika Yumemiya, who unexpectedly became his Otome to protect him from a member of Shwarz.
