As fans we should be a bit more realistic, but at the same time we should have some sort of faith in her. The tour has already started if I'm correct? Therefore we would have heard concrete evidence of it being her last tour. Rumours leak VERY easily but that doesn't make them true. If Ayu has not had an Official Statement, I won't believe that she's quitting. It's kind of saddening to see some of her fans almost making her quit with these comments.
