This is a signed ball distributed during a concert at Hulic Hall Tokyo on October 5, 2024. The single signed ball (5-6cm) has autographs from both Asato Shizuki and special guest Rio Uehara. The signed balls were distributed by going down to the seats from a basket, and this one was distributed by Asato Shizuki. (I forgot the exact number, but I think it was around 30.) I thought it would be better for a fan of either artist to have it, so I am putting it up for sale.
