for "aqwerty" at all because I chose it only from the alignment of the keyboard. I thought Rakuten nickname was used for just only a registration when I started this blog. And also it is hard for Japanese to pronounce.
That is why I was thinking to change it for a long time and I did today. "kai*" comes from my old handle which had almost the same pronunciation. Please note that "kai*" means "aqwerty". Thank you.
