Kusuriya no Hitorigoto and REJURAN COSMETICS Launch First Collaboration
TV anime Kusuriya no Hitorigoto is teaming up with Korean derma cosmetic brand REJURAN COSMETICS for the brand’s first collaboration project. The first part of the collaboration will be a mystery-solving pop-up event at @cosme TOKYO, running for seven days from October 14 to October 20, 2026. In the event, Maomao will take on the mystery of a "beautiful skin ingredient."

Hours: 11:00–21:00
Venue: @cosme TOKYO (1-14-27 Jingumae, Shibuya-ku, Tokyo)
The pop-up is an interactive mystery-solving experience. Participants will uncover the true identity of a curse and search for a "golden secret medicine."
