A “Pink Heart Jam” pop-up shop by Shikke-sensei is set to take place on the 8th floor of Shinjuku Marui Men from October 24 to November 1, 2026! Based on a “band idol” concept, the shop will feature newly drawn illustrations of Yuki Haiga and Ryo Kane playing guitar—available as acrylic stands—as well as autographed CD jackets and Cigars T-shirts. There will also be postcards as purchase bonuses and a birthday campaign for Ryo Kane.
