“Ensemble Stars,” the mobile rhythm game with more than 1.4 million followers, held a pop-up store in Seoul from Aug. 28 to Sep. 14, 2025. Centered on the theme “Innocence of Childhood,” the limited-time event invited fans into a nostalgic world brought to life through themed merchandise and immersive design.

Although the event featured only 18 of the game’s 56 main characters, it still included three of my favorites: Rei Sakuma, Adonis Otogari and Ritsu Sakuma.

The first thing that caught my eye was a large screen displaying the main illustration. As I stepped inside, I was greeted by a spacious room bathed in soft pastel tones. The entire venue felt like a utopia, as though I had been transported straight into the world of “Ensemble Stars.”

The decorations inside connected the theme of innocent childhood to the in-game story – it included constellations that relate to the newest patch of the game “The Brightest Stars” and images that represent the brotherhood and friendship of the characters.

Stalls of merchandise next to the display offered a wide range of options from accessories to decorative stands. An acrylic keychain that featured an illustration of a character and his signature immediately caught my eye. 

I noticed a pattern among the goods: most were put into a blind-box format. Resale value skyrockets based on character popularity, which limits ways to acquire them at a reasonable price compared to buying them on-site. The intention to rip off the fans over their love for the franchise let me down. 

Despite my slight disappointment, I felt a compulsion to shop there because of the limited availability. In the past, I missed out on time-bound stores and only saw items at double the price on secondhand markets, which made me regret not going to the experience myself. 

The shop gave out special gifts to high-spenders: a star-shaped clip, postcards, and lenticular cards. The star clips ran out by the time I got there, which proved the venue’s lack of preparation for the rush of customers. Unsurprisingly, resellers started to upsell at around 12,000 won or more after the event ended.

Apart from an extensive range of collectibles and photo opportunities, though, the pop-up lacked any interactive activities. This made the overall stay a little boring – some mini games or lotteries could have heightened the experience.

I would rate this experience a 9 “stars” out of 10. The variety in goods for sale and pastel-toned interior added layers to the experience, but the organization and overall entertainment fell short. Despite the downsides, the pop-up provided me with precious memories and collectibles that will forever stay in the display case of my bedroom.
