A Collaboration Realized Between Trending VTuber Shizuma Rei and Kaju Kobo Karin!

Shizuma Rei, who operates as a virtual traveler VTuber, mainly distributes content on YouTube centered around walking tours and commentary videos of Aeon Malls. She has garnered significant attention, particularly on social media, for her unique skill of identifying a specific Aeon Mall just from an image of a part of the facility. Since starting her activities in July 2024, her channel has surpassed 110,000 subscribers as of May 2026. Notably, after she introduced Kaju Kobo Karin as a "Kyusui-jo" (water station) in a video from her "Aeon Mall Walking" series, the phrase "It's a Kyusui-jo!" became a hot topic on social media. This has spread into a user-participatory movement, with customers actually visiting the stores, taking pictures of the locations and products, and posting them with the phrase.

Backed by this connection, a three-way collaboration between Shizuma Rei, Aeon Mall, and Kaju Kobo Karin has been realized. This project is implemented as part of the "Super! COOOOOOL Strategy" conducted by Aeon Mall. The "Super! COOOOOOL Strategy" is an initiative aimed at providing a "cool and fun" experience so that visitors can spend time comfortably inside the mall during the hot summer months, thereby promoting the spread of "cool sharing." It is also hoped that Kaju Kobo Karin, widely loved as a "Kyusui-jo," will become even more accessible as a place for a short break or refreshment during mall visits.

Refreshing Collaboration Drinks Perfect for Summer (3 Types Total)

During the period, three collaboration drinks finished with a refreshing taste perfect for summer will be released sequentially, one each month. Shizuma Rei herself was involved in the prototype testing, meticulously developing not only the taste but also the appearance and naming. Furthermore, the collaboration products are served in special cups featuring Shizuma Rei's original designs, allowing customers to visually enjoy the worldview of the collaboration. The lineup offers a new enjoyment with every visit, along with the ideal refreshment for the hot season and a full appreciation of the natural appeal of fruits.
