Here's a newspaper advertisement for back number! ☺︎ It's from the Yomiuri Shimbun newspaper dated December 31, 2025! It features the lyrics to "Doushitemo Doushitemo" (どうしてもどうしてもの) and the tour schedule! I'll put it in a bag and send it sandwiched in a used clear file that I have at home, with the back side included!
