>>57362670Nina's the only one that feels like it fits to me. At least for "expected" people. Seems like all signs are pointing to it being an EN, and the multiple failures on her part to re-establish herself post graduation feel like it's because she's going to debut elsewhere to handle the hype for her.
Also the hype vids thing is not evidence. Because A. something happening twice isn't really enough to call it a pattern. And B. Haruka got hype videos that people are just forgetting about. There were three of them and only the last one revealed the hand and the letter.
