THOKA YATOGAMI

            Voiced by: Marina Inoue (Japanese), Michelle Rojas (English)
She is the first Spirit saved by Shido. She transfers into his class at the end of the first volume. Shido named her for the date of their first meeting, the 10th (though one kanji is different, the tenth day of a month is pronounced as Tohka). Reine later added the Yatogami surname for her. She has long dark purple hair and purple eyes. She is ignorant of the ways of the world, but nevertheless has a normal sense of embarrassment. She seems to have strong feelings for Shido, which she is shown to be unable to understand when she gets jealous after seeing Shido accidentally kiss Yoshino. However on learning that Yoshino is a Spirit like herself she decides to support Shido in his cause to save the other Spirits such as Kurumi, even actively participating in battles at times.
She gets captured by DEM Industries at the end of volume 6, then in volume 7 on seeing Shido ambushed and is about to be killed by Ellen, she is filled with such despair that she transforms and goes on a rampage, attacking everyone in sight including Shido. However he manages to kiss her to bring her back. Westcott calls her transformed state the Demon King, adding that this transformed state is the actual form of Spirits like her in the bordering dimension that they come from before manifesting in this world.
Her Angel is Sandalphon, which takes the form of a a broadsword, usually with a throne that doubles as the scabbard, although at times it seems as though she can do just as much damage with or without it, using her hands to project dark energy spheres or bolts in order to slice through inanimate objects with ease. Her Astral Dress, Adonai Melek, consists of a purple ballgown. At full power she shatters the throne (volume 1) and combines the pieces with the sword turning the blade into Halvanhelev (the Last Sword) lengthening the blade several meters long, dramatically increasing her powers and can be charged to unleash an ultimate blow. Fortunately, the one time she used Halvanhelev charged up Shido was able to stop and seal her before the energy was unleashed. When she goes completely berserk (volume 7) her Angel changes to Nehemah, a stronger version of Sandalphon, and her Astral Dress becomes darker in color and more revealing, in this state, Isaac referred her as "Demon King" (魔王 Maō?). Her AST and Ratatoskr codename is Princess.
