YMMV / Demon Diary

• Ho Yay: There is some strong shonen-ai subtext. It's entirely innocent, but still present.
• Viewer Gender Confusion: Erutis was accidentally mistaken as a guy by many readers. The lack of gender pronouns during her introduction (in both the original and English versions) did not help matters. Erutis later Lampshades it in an omake chapter.
  • It's quite possible to mistake Raenef for a girl, too. And if you have mistaken Raenef for a girl and then realized he's a boy by the time Erutis is introduced, you will naturally overcorrect and mistake her for a boy.
