A collaboration café titled “PASTEL POP PARFAIT,” a joint project between the anime “Hetalia World★Stars”—based on the original work by Hidekazu Himaruya featuring anthropomorphic characters representing various countries—and mixx garden, will be held at the Ikebukuro and Osaka Nipponbashi locations from November 13 to December 13, 2026. The event will feature newly illustrated chibi characters wearing pastel-colored visors and holding parfait spoons, and will operate on a reservation-only basis every day.
