History YMMV / Wonderlab

* OlderThanTheyThink: Some people have taken to believing that the Abnormality Piscine Mermaid was a reference to "Bathtub Mermaid"[[note]]a song made by the indie band ''Project Mili''[[/note]], due to sharing themes of mermaids and self-mutilation for the sake of appealing to an uncaring love interest. However, said similarities are purely coincidental; MIMI has been depicting similar themes in her works long before hearing of ''Project Mili'''s music, let alone Bathtub Mermaid.

* AlternativeCharacterInterpretation: In terms of Rose's goal to change the Wings through becoming a Department Head, how much of that is based on genuine desire to make the world a better place, and how much is just meant to make themself feel better about their privileged origins, while feeling like they're doing things the "right" way rather than the best way? Rose claims to have given up the lifestyle they were raised with, but indicated that they still have access to (and make use of) their parents' wealth since their living situation far outclasses their colleagues. They've chosen to attend public school as opposed to being homeschooled for the sake of this goal, despite said choice having no apparent benefits, and also got a job working for a less influential, rigidly-structured company like L-Corp, rather than for a Wing with more control over the City where they likely could've ascended the ranks more quickly.

Rose claims to have given up the lifestyle they were raised with, but indicated that they still have access to (and make use of) their parents' wealth since their living situation far outclasses their colleagues. The path they've taken is also highly illogical; They chose to attend public school as opposed to being homeschooled for the sake of this goal, despite there being no apparent benefit for this, and also got a job working for a less influential, rigidly-structured company like L-Corp, rather than for a Wing with more control over the City where they likely could've ascended the ranks more quickly.

Moreover, they chose to work for a less influential, rigidly-structured company like L-Corp, as opposed to a Wing with more control over the City where they could've ascended the ranks more quickly.

* AlternativeCharacterInterpretation: How much of Rose's path towards changing the Wings via climbing the ranks of the Lobotomy Coeporation is based on genuine desire to change the world with their own two hands, and how much is just meant to make themself feel better about their origins in privilege while feeling like they're doing things the "right" way rather than the best way? Rose claims to have given up the lifestyle they were raised with, but indicated that they still have access to (and make use of) their parents' wealth due to their living situation far outclassing those of their colleagues. Their path towards change is also rather illogical, as they claim that they quit homeschooling with private tutors for public school towards this aim, despite the fact that there was no apparent benefit for their intended aims by doing this, and ended up entering a rigidly structured, less influential company like LobCorp, rather than a higher influence Wing that they could have likely gained access to with their family connections where they could have climbed the ranks much more quickly.

* BaseBreakingCharacter: The Servant of Wrath. Some feel that she's a cool addition to the Magical Girl Quartet, and her appearance in ''{{VideoGame/Library of Ruina}}'' was welcomed with open arms. Others feel that her design is too plain and out of place compared to her fellow magical girls, regarding it as rather underwhelming given how long the appearance of a fourth Magical Girl had been speculated on, and find her monster form to look ridiculous. Then there's the [[TakeAThirdOption third group]] that isn't keen on the Servant's design, but are willing to put up with since her appearance means more lore to the Magical Girls (such as the [[spoiler:Jester of Nihil]]).

** In Episode 52, White Lake refers to Taii as a "peasant" in the English translation. In the original Korean version, she uses the term "butcher" instead.

* {{Woolseyism}}: Though the English translation does remain relatively faithful to the original Korean release, one or two things did end up getting changed. For instance, Catt refers to the new recruits in Disciplinary as "newcomers" in the Korean version, as opposed to how it is in the English release, where they use the term "fresh meat".

* BigLippedAlligatorMoment: In Episode 10, the Department heads are all shown wearing masks and sunglasses for an unknown reason. (Though, it's eventually revealed in a Q&A that they're used to shield the Department Heads' eyes from the bright light coming from the WARP pad, but you'd have to actively know the Q&A existed to be aware of this fact.)
