LE SSERAFIM's FIM'S CLUB Opens a Secret Lab With New Pop-Up

K-Pop girl group LE SSERAFIM's official character project, FIM'S CLUB, is rolling out a new theme. The K-pop girl group is bringing its five member-designed characters into a fresh storyline built around a fictional secret laboratory.

FIM'S CLUB is a set of official characters created by the five members of LE SSERAFIM, each reflecting their own personality. The lineup includes Kim Chae-won's Kim Archi, Sakura's Sakukku, Huh Yun-jin's Heurimong, Kazuha's Zeuharong, and Hong Eun-chae's Hongppippi.

The new chapter is titled FIM'S SECRET LAB. A teaser designed to look like a flyer, headlined "Recruiting Participants for a Happy Virus Clinical Trial," was released on the 17th. A video followed on the 18th, showing the five characters developing the "happy virus" inside a dark lab. The clip runs through a series of failed experiments, including an explosion that leaves the characters covered in soot, before they finally succeed.

Fans will be able to step into the world in person. The FIM'S SECRET LAB POP UP will run from August 27 to 31 at HYBE's headquarters in Yongsan, Seoul. The space is designed around the secret lab seen in the video, with lab tables, sinks, and character plush toys styled to look scorched from the failed experiments.

Merchandise on site includes plush dolls, pouches, photocard holders, keyrings, bath bombs, and T-shirts.

The rollout shows how K-pop groups are turning character IP into another point of contact with fans. For LE SSERAFIM, FIM'S CLUB now works as both a storytelling layer and a merchandise platform, giving the group a presence that extends beyond music releases and stages.
