* BonusBoss: Challenge difficulty is designed mainly to appeal to super-whale players who can afford to have full teams of maxed-out UR Fes/Party cards and are not meant to be beatable for a vast majority of the playerbase.

** Challenge difficulty was introduced in Japan on June 4th, 2021 and globally on August 30th, with the first songs being "Yume no Tobira" and "Koi ni Naritai AQUARIUM". Unlike Expert, which is difficult but doable with some Limit Breaks, Challenge is essentially a BonusBoss difficulty with some of the hardest Appeal Chances and targets in the game and incredibly demanding stat requirements. You '''need''' the right squad of maxed [=URs=] for the selected song to stand a chance.

** To prep themselves up, [[{{Otaku}} Setsuna]] and [[GenkiGirl Rin]] perform [[ShrinkingViolet Ruby]]'s CatchPhrase [[note]]"Ganbaruby!", which combines her name with the Japanese word ganbaru (meaning "I'll do my best")[[/note]], alongside Ruby herself in the opening movie.

* OffModel:
** For [=MVs=] where multiple characters physically interact with each other, the game automatically scales certain characters if there is a height difference that would otherwise break the choreography. This is primarily noticeable by pairing characters with large height differences (Karin and Ruby, for example), and it can look quite jarring when noticed.
** Some points in Ayumu's story had her sprite appear to be ''floating'' outside of her apartment.

* ArtisticLicenseAnimalCare: During the Wondrous Winter Encounters event, [[https://static.wikia.nocookie.net/love-live-all-stars/images/a/a9/%2AGiggle%2A_Good_Night.png you could unlock a card that showed Mari laying a rabbit on its back.]] In real life, this is a terrible idea, as doing this puts rabbits into a state called "Tonic Immobility" which makes them unable to move. This fills them with fear, and could cause stress related heart problems.
