* ActorAllusion - Episode 11 of ''Purezza'', where [[Creator/FumihikoTachiki Gentou]] goes back to his days of wearing ScaryShinyGlasses and [[Anime/NeonGenesisEvangelion commanding biomechanical robots in an underground base]].
** One episode near the end has Haruka shouting, "I love anime! I love manga! I love [[Creator/MamikoNoto Noto Mamiko-san]]!"[[note]]Her own voice actor.[[/note]]
* RelationshipVoiceActor - [[Creator/FumihikoTachiki Gentou]] and [[Creator/AyaHisakawa Akiho]] used to be Shinigami teammates as [[Manga/{{Bleach}} Kenpachi and Retsu]], respectively.
** ''Purezza'' gives us [[Creator/MamikoNoto Haruka]] and [[Creator/RieKugimiya Touka]] -- a tandem not seen since [[LightNovel/TheFamiliarOfZero Tiffania and Louise]] and [[LightNovel/ShakuganNoShana Hecate and Shana]].
** [[Creator/KaoriShimizu Hazuki]] and [[Creator/KanaUeda Nanami]] are like the inverted version of the relationship between [[LyricalNanoha Signum and Hayate]].
** [[Creator/MamikoNoto Haruka]] and [[Creator/RinaSato Shiina]] are like a JustFriends version of [[Manga/MahouSenseiNegima Nodoka and Negi]], although there's a bit of LesYay going on here.
