I'm not saying its entirely lazy, just that I don't like it atm. I guess we'll have to wait for Yoshiko's comments though.
Like how TokiSora some parts of the dance are really sharp, and she's like "oh when I got the song early, I had a different impression". She would be the type of person to be like "I reused moves" to incorporate past singles since it is her last single though hypothetically if there are more resued moves. Also the syllables thing really reminds me of Brainstorming as well just because of the voice processing.
