alterna is not one of her hardest PVs to interpret! It actually has a pretty clear message, but told in a weird and scary way! Its one of her most powerful PVs I think. A big f u to avex.
For me - Mirrorcle World: I still don't know if there's any meaning behind it or whether its just random. A lot of the interpretations that came from it on this forum when it first came out seemed to be grasping onto anything to make a story out of it. Haven't been satisfied with anything I've read. Sometimes I think she just did a video to show off she went to Paris.
You were... is another recent one. Whatever the message is, its buried really deep. I kinda understood aspects of it, but not the video as a whole. Really artistically done, but hard to follow.
