Hmmm... I think that Ayu and Da Pump should do another duet together! I really liked the song that they did for AyuReady together! They harmonized perfectly!
As for Hikki.... I think that her and Ayu's voice just won't mix at all... and not to mention that Hikki, at least in the U.S., is always regarded as having a voice 100 times better than Ayu's.... which I don't believe but I think that Ayu and her voice might be drowned! It's so fragile and girlish!
