Hitomi, just like Hajime, was a member of the literature club back in her high school years. She fell in love with Hajime back in high school, but after graduation they lost contact for two years. One rainy night, Hajime appeared in front of her apparment asking her to let him stay. Six months later, Hajime tells her everything about the fairy war and the powers. She joins him and became the first member of Fallen Black. She is well respected in the group because she is a very responsible person, nothing like the carefree Hajime. They seem to get along, and they are very close.
