Michiru (満) was a spellcaster (majinaishi) that served the Commander eight years ago, when he was occupying the body of The King. She was in charge of selecting and kidnapping young boys that had decent potential as Puppet Soldiers. Though she accidentally picked up Kakeru who merely looked like a boy, after Michiru discovered Kakeru's enormous power as a Spirit Reservoir Owner and considerable talent for spells, she began training Kakeru as her assistant. Both Michiru and Kakeru are responsible for the Shinyuuchi huntings, though they were initially acting on orders from Tsukihisa Oumi (then using the name Gyoku).
