* AdaptationalBackstoryChange: Unlike in ''ALL STARS'', Kaoruko is neither the head nor even a member of the School Idol Committee in the anime as Yu is its founder instead in that continuity. The anime also reveals that she used to be part of a school idol group when she went to Shion Girls Academy in high school, but one that failed to enter Love Live in the qualifiers and that she willingly gave up on becoming a school idol after that happened. Because of all these factors, it's highly unlikely that she shirked her duty as the next head of the Mifune family in favor of pursuing her school idol dreams in the anime's continuity, despite still being highly supportive of school idols in general.

The anime also reveals that she used to be part of a school idol group when she went to Shion Girls Academy in high school, but one that failed to enter Love Live in the qualifiers and that she willingly gave up on becoming a school idol after that happened. This is in contrast with her backstory in the game, where it's implied that she was more of a school idol supporter and not a school idol despite her love for them just like the Protagonist. Because of all these factors, it's highly unlikely that she shirked her duty as the next head of the Mifune family in favor of pursuing her school idol dreams in the anime's continuity, despite still being highly supportive of school idols in general.

* DubNameChange: The English version of ''ALL STARS'' translated Hanpen's name as "Fishpuff". Notably, the cat is one of the few characters in the franchise to have a different official English name from its original Japanese one. Averted in the English dub of the anime, where the characters continue to call the cat Hanpen.

* IllGirl: It's revealed later on that her fairly weak constitution caused her to be hospitalized often when she was younger. Ai would visit her in the hospital to cheer her up, which eventually caused Ai to develop her PungeonMaster habit when she realized that Misato found it funny.

\\\
A kind woman who serves as Ai's older sister figure. Although the two are not related by blood, their bond is deep enough for Ai to treat her like a relative. Despite her physical weakness, she supports Ai in all of her endeavors and plays a key role in her uprising as a school idol.

* AdaptationalAngstUpgrade: The anime explores how depressed and left out she feels after being constantly hospitalized for most of her life, something the game didn't delve on much. She also feels guilty for being unable to feel happy like she should be for Ai despite wanting to be and for envying her little sister figure for being able to find something she would be passionate over, something Misato feels she can't do until Diver Diva convinces her otherwise.
* ChildhoodFriends: With Ai.
* CoolBigSis: Ai looks up to her and calls her "Onee-chan".
* CurtainsMatchTheWindow: Has brown hair and brown eyes.
* IllGirl: It's revealed later on that her fairly weak constitution caused her to be hospitalized often when she was younger. Ai would visit her in the hospital to cheer her up, which eventually caused Ai to develop her PungeonMaster habit when she realized that Misato found it funny.
* MotherlySidePlait: It highlights her gentle and caring personality.
* NiceGirl: Misato is very gentle, polite, kind and caring, and a very nice CoolBigSis figure for Ai.
* StepfordSmiler: As Karin, and later, Ai notice in the anime, Misato's burying her sadness over her inability to catch up with Ai now that Ai has found something to be passionate about. She genuinely wants to be happy for Ai, but secretly envies her and feels terrible about it. She gets better.
* WhatTheHellHero: After Ai praises the Club for overcoming their obstacle of Lanzhu's oppresion of their Club, Misato bluntly asks Ai why she defected from the Club. This leads to Ai revealing her inferiority complex toward Setsuna, Kanata, and Kasumi.

* AscendedExtra: Ironically, in the poll that determined which three Normal rarity girls would become part of ''Perfect Dream Project'', Himeno placed 4th right under Kanata Konoe, locking her out of a position in Nijigasaki. However, when the ''Nijigasaki'' anime premiered, Himeno debuted as a recurring minor character as the representative for Touou's School Idol Club.

* CaligulasHorse: After discovering that neither Rina nor Ai could take Hanpen home with them, Setsuna appoints the cat as the student council's official trekking officer, [[LoopholeAbuse exploiting a loophole]] so that it could remain at the school.
* DubNameChange: The English version of ''ALL STARS'' translated Hanpen's name as "Fishpuff". Notably, the cat is one of the few characters in the franchise to have a different official English name from its original Japanese one. This does not apply to the anime.

* BrokenPedestal: It's revealed that Kaoruko was a shoo-in for the next head of the Mifune family, but she gave up the role in favor of following her dream of being a school idol. Shioriko, who believed that success makes people happy, interpreted this action as her sister throwing away her chance at success for a fleeting dream, and came to resent both her and school idols in turn.

* StrongFamilyResemblance: It's easy to see that she and Shioriko are related even before the reveal.

* CoolBigSis: Ai looks up to her and calls her "Onee-san".
