The collaborative character "Ireisu minini," born from a partnership between global character brand LINE FRIENDS and 6-member 2.5D idol group Irregular Dice, is getting its very first POPUP event. "Ireisu minini 1st POPUP: DREAM POP STAGE" will be held at LINE FRIENDS SQUARE SHIBUYA from March 20 (Fri) to April 6 (Mon), 2026.
New Character "Ireisu minini"
LINE FRIENDS has developed collaboration IPs with a wide range of artists including BT21 (BTS), G-DRAGON, and ZEROBASEONE, building a fanbase around the world. Its latest collaboration brings together the brand with Irregular Dice, a group making a major impact in the 2.5D idol scene.
The concept imagines Irregular Dice and their companions "Mofumate" shrinking to the same size in a dream and growing even closer. Drawing on each member's unique personality and charm, the characters have been reimagined in the LINE FRIENDS minini style. "Ireisu minini" made its debut in October 2025 to an enthusiastic response.
