>>70127523I don’t really know to be honest. My best guess is because Scarle could very likely have little to no enemies in Nijisanji for a variety of reasons. One of the reasons is because several EN members have said that she is probably the nicest person in EN. Kyo even told her he will not teach Scarle how to “roast” people because she is “way too nice for her own good.”
Another reason could be because Scarle has stated, at least twice during streams, that she actively avoids any form of confrontation because she hates getting into drama and arguments, probably due to her near-crippling social anxiety. She then followed it up with that she avoids getting into arguments because she feels super bad afterwards and tends to feel like it’s always her fault (which was very evident when she kept apologizing to Aster in the DM leak).
Her extreme shyness is another reason why she most likely has barely any enemies in NijiEN. She has stated several times that she doesn’t talk to, nor hasn’t interacted with a lot of the EN members, other than a select few (ie: Hex, Fulgur, Zaion, Selen, Nina, and the rest of Iluna). In a stream just days after Pomu graduated, Scarle even admitted that she spoke to both Mysta and Pomu for the first time during their graduation streams.
As for why Selen/Doki got canned, we already know a lot of what went down, and it could also be very likely due to jealously and envy amongst the clique members due to how successful Selen/Doki was.
