After School's leader, Kahi performed her last stage with the group.

On June 17, After School performed their encore concert in Japan at the Tokyo Dome City Hall. This concert was also the day they announced Kahi's graduation to pursue her solo career.

After School's agency commented, "Kahi's solo stage at this particular concert showcased her hard work. You could tell that she put in a lot of effort to bring her fans the best show."

The entire concert was filled with tears and sadness as this would be the last time they would see Kahi as an After School member. Kahi commented, "I have no regrets with the outcome of this concert. I was happy to be the leader of After School. After I graduate, I will continue to grow and learn new things and show my fans a new side of me."

With Kahi's graduation coming to an end, After School will be coming back with new faces on June 21.
