I remember there was a technical problem during AT06, alterna to is this LOVE transition. The floating orb cage for alterna cannot be lowered down so Ayu, along with Shuya and Go-mi inside the orb, performs is this LOVE from the orb while improvising, she looks scared and ridiculous at the same time lol. idk about (miss)understood but I supposed the song was cut from the set list to get to lower the orb down. You can see it on CDL06~07 Documentary.
Maybe that's why we haven't see another floating act as extreme as alterna in the past years.
And admin maybe can help moving this thread to Chat Room
