A bookstore fair starting June 18, 2026 offers newly drawn collaboration illustration cards featuring characters from The Apothecary Diaries and COSMOS. Customers who buy Volume 22 of The Apothecary Diaries: Maomao's Imperial Palace Puzzle Solving Notebook or Volume 9 of COSMOS at participating stores receive a card. The cards are drawn by the opposite series' artist: Ryohei Tamura draws Maomao and Jinshi, and Minoshi Kurata draws Rin and Mizumori.
Two manga series from the same magazine are crossing over at the bookstore counter. Starting June 18, customers who buy Volume 22 of The Apothecary Diaries: Maomao's Imperial Palace Puzzle Solving Notebook or Volume 9 of Ryohei Tamura's COSMOS at participating stores nationwide will receive a newly drawn collaboration illustration card. The gimmick is a straight artist swap: Tamura drew Maomao and Jinshi from The Apothecary Diaries, and Minoshi Kurata-the manga artist for The Apothecary Diaries adaptation-drew Rin and Mizumori from COSMOS. The cards have different finishes, metallic for Tamura's and washi paper-like for Kurata's, and are sized to fit inside a phone case. Volume 22 of The Apothecary Diaries also gets a special edition with masking tape for ¥2,200.
