Single InformationEdit


Nana-iro no Kutsu

"We spend our days feeling various ways. What color will your shoes have today? If you wear shoes in your color and open the door, a new day awaits you."


"It’s difficult to meet people halfways. But, everything that’s really important is usually very simple. The language of the flower «Iris» is: I love you. I wrote this song with that kind of feelings."
