History Characters / BangDreamRoselia

* CatSmile: Her default expression, thanks to the way her lips are designed. Most notably so in the chibi-style artworks of ''Garupa PICO!'', though it's also present in the game as well, both on the chibi and the [=Live2D=] model.
** Even better, her second seiyuu also has a very catlike grin.

* {{Hyprocrite}}: She often gets exasperated by Hina's [[BrutalHonesty poor sense of tact]] as much as she tends to call her out for her InnocentlyInsensitive moments... yet she's no better than her own younger twin sister herself when it comes to being blunt and less mindful towards the feelings of other people.

* GamerChick: After the "Neo Fantasy Online" event, Sayo takes a liking to play NFO just like Ako and Rinko, with certain dialogues suggesting she plays the game and is skilled at it as much as them.

* BreakoutCharacter: Group example. Having only appeared in a single episode in Season 1, and with minimal dialogue at that, does ''not'' prevent Roselia from being the first band in the franchise to release a full-length album, despite only being in the second place when it comes to the number of singles released. They're also the first band of the franchise to do an opening song [[Anime/CardfightVanguard for another anime.]]

* SourOutsideSadInside: Despite presenting herself as a no-nonsense perfectionist and a seemingly standoffish jerk, it's mainly because she resents her more successful younger twin sister and often has a lot of trouble trying to deal with her inferiority complex issues in a healthy manner. As such, there were implications wherein her {{Jerkass}} behavior was used as a coping mechanism to mostly hide how insecure she is deep down. Fortunately, she gradually becomes a much better person over time after she finds the courage to finally open up about her personal issues with Hina and her other friends, averting this trope in the process.

* SourInsideSadInside: Despite presenting herself as a no-nonsense perfectionist and a seemingly standoffish jerk, it's mainly because she resents her more successful younger twin sister and often has a lot of trouble trying to deal with her inferiority complex issues in a healthy manner.

* {{Chuunibyou}}: Has a more realistic variant of this than most, as instead of seeming to assume that she ''is'' the character, she takes great joy in basically roleplaying being a Demon King and the like.

* AloofBigSister: Played with: rather than Sayo being the impressive older twin and having an aloof attitude toward her younger twin, it’s Hina who’s effortlessly more impressive, which is precisely the reason Sayo acts cold towards her. Deep down, she greatly regrets the way she treats her sister. Later stories and events see Sayo lessening the "aloof" aspect as part of her wish to be more honest with Hina, and as part of the promise the two shared with one another.

* CharacterDevelopment: The “Umbrella in the Autumn Rain” event story deals with her trying to find her sound and [[spoiler:realizing that she’s bottling up her insecurities revolving around her guitar-playing and jealousy towards Hina. By the end of the story, she’s making an effort to be kinder to Hina.]] After this story, Sayo slowly becomes less bullheaded and more open, and she even attends a cooking class at Tsugumi’s cafe in hopes of trying to cater for Roselia in case Lisa isn’t around.

* TheDeterminator: Her use of language and stubbornness gives this impression. She says she "has no choice" but to improve her guitar-playing and "I won't lose!" at one point.
* DoesNotLikeSpam: She hates carrots with a passion, although ironically, it's her sister who doesn't like carrots when they're younger, prior to the current time where Hina doesn't have problems with eating carrots.

* TheDragon: Acts as this to Yukina when she needs it, and does so unironically. That being said, [[spoiler:she's also the most upset to hear about Yukina considering going solo to Future World Fes.]]

* {{Foil}}: She and Yukina are both the serious and demanding members of the band, in contrast to Lisa, Ako and Rinko, but upon closer examination, they have many differences. While Yukina is motivated to play because of what happened to her father, and because she wants to impress him, Sayo wants to outdo her sister in the one thing she considers hers. [[spoiler: Yukina even considering leaving the others behind to go solo to Future World Fes also upsets Sayo, who had wanted to play in a band full of people who had comparable talent and determination]].
* FreudianExcuse: [[SuccessfulSiblingSyndrome Given Hina's tendency to outdo her at many things despite her best efforts]], it's not too hard to sympathize with Sayo and her reason why she resents Hina so much to the point where she became obsessed with the guitar (the only thing she initially thought Hina won't take away from her) and wants to stand out so badly from her highly-talented younger twin sister's shadow. However though...
* FreudianExcuseIsNoExcuse: ... it should be pretty much clear that having [[InferioritySuperiorityComplex a major inferiority complex issue]] obviously ''shouldn't'' give her a free pass to take out her negativity and frustrations onto others (just like how she once angrily lashed out at Ako when she gushed over Tomoe in Roselia's first band story), treat her own younger twin sister like shit, or go around acting like a rude {{Jerkass}} in general. After the events of "Umbrella Under the Autumn Rain," [[CharacterDevelopment she ultimately improves herself both as a sister to Hina and as a person overall following their reconciliation]].

* ThePerfectionist: She’s so particular about getting things perfectly right that not knowing what to do exactly basically forces her to stop in her tracks. In one case, she even uses a ruler in a baking class to measure the precise thickness of the dough. Yukina notices that what Sayo considers a "mistake" is being a split-second late, [[LampshadeHanging and acknowledges Sayo has high standards for herself]].

* GoneHorriblyRight: During the "Neo-Aspect" story arc, she somehow managed to enforce the "Roselia doesn't need friendship" belief onto her fellow band members following Roselia's failure at the SMS and relapse to her old negative self because she adamantly believes such a thing to be a hindrance to the band and their goals... but it worked out too well with less than favorable results. Her relationship with her band became increasingly strained to the point where Ako and Rinko ran off on her after they couldn't take any of her abusive {{Jerkass}} behavior much longer, Lisa and Sayo showing nothing but disappointment towards her attitude, and Roselia nearly disbanding. [[AvertedTrope Thankfully, the worse never comes to happen as Kasumi and Sayo were able to help steer her back into the right direction and atone for her mistakes.]]

* HumanizingTears: Sheds these somewhere during the climax of the "Neo-Aspect" story arc. Yukina always presents herself as a stoic and aloof person, but following her massive argument with her fellow bandmates, [[TearsOfRemorse she breaks down in tears out of genuine guilt and remorse over what transpired earlier]]. This shows that despite her difficulty in expressing her emotions, she deeply regrets the way things badly turned out between her and Roselia because of her selfishness and bottled-up insecurities.

* LargeHam: During the "Kokoro's Eternal Halloween" event where she got a little ''too'' into character as a Queen of Darkness after some convincing from Ako.

* TheLeader: She's the face and founder of Roselia. As she's the center of it all, all of its members gathered primarily because of her. Though it's not without its burdens as Yukina reveals that she has deep insecurities over her role as Roselia's leader despite the bravado she shows her bandmates.

* NotQuiteTheRightThing: In Band Story 2, she reverts back to her old personality after the SMS event, believing that the [[LoveIsAWeakness the band becoming more friendly with each other affected their performance.]] This causes a rift within Roselia.
* NotSoAboveItAll: She has a secret goofy side underneath all that ice in spite of her efforts to hide it. Her common sense gets essentially thrown out the window whenever cats get in the picture.

* ProperLady: Acts like this most of the time. Unless she happens to be nearby a cat, or have a moment of being NotSoAboveItAll.

* TheRival: Yukina and Afterglow’s Ran share this view towards each other, constantly trying to prove that they’re the best (which ironically pushes both bands to become even better), either despite having Yukina having more in common with Ran than with her own bandmates, or because she has more in common with Ran. Many of their random conversations tend to end with one of them thinking “Why do I feel like I just lost?”

* TalentedButTrained: She's an incredibly gifted singer, but has mentioned time and again that she needs to constantly practice to retain and further improve her talent. She imparts and instills this wisdom to her fellow Roselia members as well by ensuring that they regularly have band practice so their skills would never end up dulling.
* TookALevelInJerkass: [[spoiler: During Roselia's second band story, the band's supposedly poor performance at an SMS event results in her lasping back into her old IceQueen self, and she's even worse than before, insisting that Lisa stop baking cookies for the band and [[KickTheDog regularly belittling poor Ako]]. It culminates in Ako lashing out at her to the point where she breaks down crying and is unable to bring herself to attend rehearsals. She eventually gets better.]]

* UsedToBeASweetKid: She used to be a whole lot more cheerful in personality and was a much openly sweeter friend towards Lisa as a child, but her father's spiral into depression following his dream of entering Future World Fes getting crushed in spite of his great talent transformed her into the aloof, perfectionist ice queen she is in the present. She's slowly becoming the child she once was again the longer she bonds with Roselia however.

* WellTrainedButInexperienced: While she may have a highly impressive talent and knowledge for music, it is evident during the early days of Roselia that she had little to no experience when it comes to leadership within a band. As such, her unhealthy perfectionistic mindset and initial flawed style of leadership ([[NoSocialSkills not helped either by her poor social skills]]) nearly caused Roselia to nearly disband at one point following a massive argument between her and her fellow band members from their failure at the SMS event. Luckily, she slowly evolves into a much kinder and better leader later on through experience as the story progresses.

* FreudianExcuse: [[SuccessfulSiblingSyndrome Given Hina's tendency to outdo her at many things despite her best efforts]], it's not too hard to sympathize with Sayo and understand the reason why she resents Hina so much to the point where she became obsessed with the guitar (the only thing she initially thought Hina won't take away from her) and wants to stand out so badly from her highly-talented younger twin sister's shadow. However though...

As such, her unhealthy perfectionistic mindset and initial lackluster style of leadership ([[NoSocialSkills not helped either by her poor social skills]]) nearly caused Roselia to nearly disband at one point following a massive argument between her and her fellow band members from their failure at the SMS event. Luckily, she slowly evolves into a much kinder and better leader later on through experience as the story progresses.
* WhatTheHellHero: [[spoiler:On the receiving end of it. Ako and Sayo both respectively felt betrayed with Yukina considering on going alone for the Future World Fes]].
* WhenSheSmiles: While normally stoic, she has one of the best and gentlest smiles in the cast. It's this side of her that Lisa wants to bring out more out of her in fact.

* GoneHorriblyRight: During the "Neo-Aspect" story arc, she somehow managed to enforce the "Roselia doesn't need friendship" belief onto her fellow band members following Roselia's failure at the SMS and relapse to her old negative self because she adamantly believes such a thing to be a hindrance to the band and their goals... but it worked out too well with less than favorable results.
