... Who's "Demon Lord Dezastoll"?
@hyrule13: So you're dropping this manga?
@kashiwa_mae: I think you mistranslated the speech bubble in page 2, third panel. Chapter 14.5 revealed that Yuuhi earned the nickname of "The Sunset Witch"; I'm assuming that you confused 夕日 or 夕陽 for Yuuhi's name, since the kanji is pronounced that way and does mean "evening/setting sun" (i.e. "sunset").
Also, what's with the use of "human country"* and "magic clan" on page 5 instead of "human kindgom" and "demon race"? And IINM, "Rameru" (page 12) and "Arize" (page 20 and 22) are supposed to be "Ramel" and "Alize", respectively. I suggest you should check past chapters for reference on some of these term and name translations/romanizations, if only to maintain consistency if there's no real indication what the correct translation/romanization is.
* This one is really unnatural sounding in English and bugs the fuck out of me whenever I see it in a translation.
