If it will sell 150,000 or over I think it will be really good since ayu does so well with a song that isn't really something everyone would like easily and she wanted to release it as a part of her, so if it will sell even 150,000 it will be good for a song such as Mirrorcle World which is not really mainstream and catcthy, nor ballad or a cute song.
And it was an interlude in GUILTY so everyone heard like almost 2 minutes from the song already in Mirror. So if it will do it I think it should be refered as a successful single.
