I've never watched a full Kuu concert (which I totally should, because Step Into My World from the Universe tour is EPIC), so I can't say anything about her tours.
But Ayu's tours are usually predictable. Oh it's the tissue dance again, Oh it's the pretty-dress-ballad part again.
I do absolutely LOVE Ayu's tours, and I'll never grow tired of watching them, but it would be nice if she kinda changed the routine a little bit. Like.. I dunno, sing a ballad in something other than a dress with ugly shoulder pads. (she's done that like 3 or 4 times in a row now, I believe).
Now that I think about it, I only dislike Ayu's ballad parts
her upbeat and rock sessions I'm very happy with.
