LINE FRIENDS, the digital IP entertainment company also known as IPX, has announced the arrival of its second MIGHTEEZ pop-up experience titled 'MIGHTEEZ Wonder Room' in the United States. This venture follows the sold-out run in Korea, where pre-reservations filled within five minutes.
The new MIGHTEEZ Wonder Room is taking place from May 8 to May 17, 2026, at LINE FRIENDS SQUARE locations in New York and Los Angeles as well as the brand's US online store. The pop-up event centers on characters created in collaboration with the K-pop group ATEEZ, where each member is reimagined as a fairy possessing unique superpowers. The narrative framework of the pop-up involves a secret attic hideout where these fairy characters grow from babies into fully powered beings, a storyline reflected in merchandise such as plush keyrings showing them studying magic and Baby MIGHTEEZ versions featuring smaller ears and wings to indicate their early developmental stage.
