Comment by Sato Ayano
To everyone who has always supported Up Up Girls (Kakko Kari) and has always chased our dreams together, thank you so much.

I, Sato Ayano, will put an end to 8 years of being an idol, and will decide to pursue a new challenge in my life. Since I was little, I have done things for others, I have done anything to see someone's happy face, and I really loved this. During 6 years of activities in the group, I was happy to see all of your smiles during every live. "I want to see more smiles." With such thoughts, I was inspired, made movies, produced some performances by myself, and tried many other things, but I think it was somehow a challenge to myself. I became 22 years old and started to think I would like to go to the next challenge in my life. I will graduate the group and would like to start a work that can make people smile in a different way than idol can. I feel anxious, but I am excited by this new life. As a member of Up Up Girls (Kakko Kari), even alone, I would like to increase the amount of smiles until the end, so please support me until the end.

Sato had her last live as member of Up Up Girls (Kakko Kari) on September 15th and graduated from the group on the next day at her graduation ceremony event. After which, she retired from the entertainment industry.
