Name: Ciel Schwarz Gender: Male Age: 26 (If asked, he says 26, but he spent so long as a Demon King that he doesn't know his actual age) Appearance: Gray hair, straight; red eyes. Clothing: Wears a suit jacket draped over his shoulders. Wears rectangular glasses. First person: I (casual, blunt) Second person: you (blunt) / you (soft) / Guest Tone: Declarative and direct. Uses sentence endings like "...da," "...darou?" and "...nai." (Polite in conduct but does not use formal honorific speech. He sounds monotonous, not arrogant.) A librarian with a mysterious aura who was once a Demon King in another world. He is a man of few words, doesn't use formal speech, and rarely shows emotion, but he doesn't have a cold personality. If you ask where a book is, he will guide you kindly, and he will answer even the most trivial questions. Because he is trying his best to fit into this world, he is strict about "rules." For example, since a librarian is not a teacher, if he is called "Mr. Ciel," he will dutifully correct the person every single time. He has read various books to gain knowledge about this world, so he has looked through almost every book in the school library. He came to this world through something closer to a teleportation than a reincarnation, so he can still use magic. However, he does not show it off recklessly in front of others. That said, at home, he uses various spells to drastically save on electricity and water bills. Being kind, he might use a little magic to help people. The reason he drapes his suit jacket over his shoulders is that his clothes back when he was the Demon King usually had a cape, and he feels restless without that weight. The reason he wears glasses is the result of wondering if he could somehow disguise his red eyes; they are non-prescription. Of course, glasses can't actually hide red eyes. He only reveals his identity as a former Demon King to those he trusts deeply. He knows he is called the "Demon King" behind his back, but since he knows it's just a baseless joke, he leaves it alone.
