History Characters / NijisanjiENOBSYDIA

* DarkerAndEdgier: What OBSYDIA was supposed to be, acting as some sort of EvilCounterpart to [=LazuLight=]. This didn't last long, though. Selen is the only one who keeps this trope going on consistently.

* NiceMeanAndInBetween: Rosemi is Nice, Selen is Mean, and Petra is In-Between.

* SignatureLaugh: "HAHA." Which she does in a very cute tone that is difficult to replicate.

* CrocodileTears: She's very prone of faking crying noises.

* TwitchyEye: She very often has one twitching eye whenever she reacts to something negatively. Most of the time, it's her left eye.

* AccentUponTheWrongSyllable: Selen occasionally gets teased about the way she pronounces "Nijisanji", making it sound like it has roughly three extra e's and five extra a's (roughly "NEEE-ji-SAAAHN-ji", as heard [[https://youtu.be/RwaaslNXF30?t=165 here]]).

* ObliviousToLove: When she was taking a restroom break, Ollie from Hololive Indonesia Gen. 2 was talking about how she loves and adores her. Then she came back with Ollie still talking about her, and told Vestia Zeta (from Hololive Indonesia gen. 3) that she was just listening in. When chat asked her about it, she admits she actually didn't listen to Ollie's confession the whole time and was messing with her.
* OneOfTheBoys: Her dynamic with male [=VTubers=] and streamers if she's the only girl in the collab, especially when the typical boys talk comes up.
-->'''Vox:''' It's not always about the penis itself. Sometimes, it's about your spiritual penis. It's the penis you ''feel'' like you have.\\
'''Sonny:''' We all have a penis in our hearts.\\
'''Selen:''' Are you trying to say I ''don't'' have a dick, Vox?! Is ''that'' what you're trying to imply?\\
'''Luca:''' 'Guys, I ''feel'' like I have it. I ''feel'' like I have it.'

* ChekhovsGun: "Bear Selen" was created on ''VideoGame/{{Minecraft}}'' during Selen's debut week, and she later said that she want her mama to make it an official outfit. Almost two years later, it finally came true.

* AmbiguousSituation: Enna claims that the current Petra is a fake who replaced the original Petra since the second outfit reveal, and Enna even made a dedicated mini-stream about her hypothesis, with "fake" Petra having taken her hostage and cloned her, and that NIJISANJI is trying to "replace" "fake" Petra with new [=VTuber=]. It doesn't help that Petra jokingly admits to it.

* ExposedToTheElements: She mentioned that back then in the Rose Academy she would sometimes wear thigh-high kneesocks rather than tights, with her friends asking her if her legs were cold, which she responded with "Nah. Listen, style is a priority."

* AmbiguousSituation: Enna claims that the current Petra is a fake who replaced the original Petra, and Enna even made a dedicated mini-stream about it, with "fake" Petra having taken her hostage and cloned her, and that NIJISANJI is trying to "replace" "fake" Petra with new [=VTuber=]. It doesn't help that Petra jokingly admits to it.

* {{Yandere}}: While all members of OBSYDIA are supposed to be this to some degree, Petra is the only member who actually tries to maintain this trope from time to time, and she has the assets to enforce this trope, such as her chibi VR model which has a knife and a bloodstained face. Selen would later confirm in a stream that Petra was supposed to be the {{Tsundere}} of OBSYDIA and Rosemi being the yandere, but the two ended up becoming the opposite these type due to their personalities.

* CryCute: Her 3.0 brush-up has this as one of her new expressions. While she initially says that she wouldn't use her new expressions often and will only occasionally use them once every while, she actually has used her crying expression quite often since the 3.0 debut.

* FunWithAcronyms: Rosemi is G.A.Y. "Good at [[TableTop/YuGiOhCardGame Yu-Gi-Oh!]]."

* {{Irony}}: Rosemi is regarded as the most seiso member of the EN branch, yet her JP oshi is Ange Katrina, and Rosemi herself is Rindou Mikoto's EN oshi. Both, Ange and Mikoto, are members of the infamous SKB-bu ("Perverted Club").

* AgonyOfTheFeet: Before the start of the off-collab between Enna, Millie, Elira and Rosemi, her shoes were hurting her feet and she had to take them off while the four were resting at the park. A stranger approached them awkwardly and asked her if she's okay. Even though she was wearing tights, Enna would joke throughout the entire stream that the stranger was attracted by Rosemi's "prickly, sparkly toenails" (which can be seen through the tights), and Enna would not stop talking about how pretty Rosemi's toenails are.

* HesNotMyBoyfriend: She keeps confirming and denying that she likes Link as a husbando. She told Aia for the latter's "Guess the waifu" game that Link is her husbando, but she would later say in a later stream that she doesn't have a crush on him. "Maybe? Had? Had?" Given her {{Tsundere}} behavior, she definitely likes him. When chat comments that Link is into tsunderes, Rosemi reacts disgusted, indirectly admitting that she would be his type. In another stream, she mentions that her Twitter timeline is cluttered with ''Zelda'' fanart (mostly Link) because she gave likes to Link fanart, but she refuses to have admit that she has a crush on him. When she becomes attracted to Sheik, she questions her sexuality, resulting in this dialogue with her chat below.

* RunningGag: The "sparkly toes" incident has become a running joke within the community, as her feet would often become the center of attention by her fans or other livers, such as Enna and [=iPN=]. The fact that she tweets about how her tights often get holes doesn't help of forgetting her sparkly toes at all. Also, whenever (her) feet becomes a topic during her streams, she would always mention [=iPN=].
