Tohka is the first Spirit saved by Shido. She transfers into his class at the end of the first volume. Shido named her after the day of their first meeting, April 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.
