Iris Mysteria! is the main title of the series, with the subtitle "Shoujo no Tsumugu Yume no Hiseki" indicating a specific variant or installment rather than the core franchise name. The series is part of a Japanese multimedia project centered on fantasy, school life, and character-driven storytelling, often associated with bishoujo game and anime-style presentation. For matching purposes, the most commonly used master title is the shorter series name without the subtitle.
