Unnamed Characters in La Noche de Walpurgis
- In order of appearance:
Witchcraft club members
Unknown members of the original witchcraft club that existed twelve years prior to the events of the series are featured at the start of the first episode and in Reika Kitami's flashback in the third. Their appearance was altered in the remastered version of this episode.
Students in shock
Two students, possibly prefects working for the student council, are ordered by council president Rika Shiraki to pull students Asada and Murai apart after they blatantly start having sex in the school's hallway.
Classmates and teacher
Art club students
A group of at least eight male students, presumably members of the Academy art club, rape their teacher Hiroko Takashiro and fellow student Rika Shiraki under the evil Reika Kitami's command. The boys are possibly being coerced by her magic influence.
Kitami's male lackeys
After Reika Kitami kidnaps student Kurumi Imari, she has several male followers hold her down and violate her. They later have sex with Kitami's ritual girls and break into Minase's house to rape Rika Shiraki and Minase's cousin Yukiko. The men are likely Academy students as well, possibly some of the same students that participated in the art club orgy (see above).
A group of several girls (excluding Kaori Saeki, Jun Amatsuki and Maki Kurimoto) that assist Reika Kitami during her ritual on Walpurgis Night. They are first used as concubines in preparation of the ritual in order to help Kitami's male lackeys fill a golden chalice. The girls are most likely students and possibly members of Saeki's coven that have also had their minds corrupted by the evil witch Kitami.
An Academy prefect takes notes from two students following the incident in the school's basement on the Night of Walpurgis. Since the two students are the target of questioning, it is possible they were members of Kitami's coven who have lost their memories of the events, either due to Kitami's spell on them being broken or Takashiro having wiped their memories.
