there are actually three albums with different seiyuu, but in the Video size all the voices from those three albums are combined. i'm ain't too interested in duplicating each seiyuu in the artist as i don't see the point; if each of those albums has a seiyuu voice? besides en avant members voice were somehow in the forefront, in this version they are just in the background. But I'll be thinking whether I like that aesthetic or not... https://columbia.jp/prod-info/COCX-31694/
