Kajitsu Kobo Karin, a fresh fruit juice specialty shop operated by Aoki Fruit, has announced an expansion of its ongoing VTuber collaboration campaign with Sizma Rei, titled “Hydrate at Kajitsu Kobo Karin in AEON Mall!” Due to popular demand, the campaign will add 7 new locations starting July 18, 2026 (Sat), bringing the total to 92 participating stores. On X, posts using the hashtag #イオンモールの果琳で給水 (Hydrate at Karin in AEON Mall) have reached approximately 3,000.

Popular Demand Drives Expansion to 92 Stores

This campaign is part of AEON Mall’s “Super COOOOOOL Strategy” initiative and has been running at Kajitsu Kobo Karin locations inside AEON Malls nationwide since June 1, 2026. The campaign features a collaboration with Sizma Rei, a “virtual travel” VTuber known for exploring and analyzing AEON Malls, with a different collab drink offered each month.

The June limited collab drink, “Thick Mango & Apple,” was a hit from day one, with fans flooding X with “last chance to try it” posts on its final day. In response to this enthusiasm, the campaign has expanded beyond Kajitsu Kobo Karin to also include “Wonder Fruits” and “V²&M by FruitsBar AOKI” locations. The 7 additional stores span Ibaraki, Chiba, Kanagawa, Aichi, Nagano, and Gifu prefectures, bringing the total to 92.

Sizma Rei Personally Sends Messages in X Posting Campaign

Alongside the collab drinks, the campaign includes an X posting initiative where Sizma Rei personally sends “AEON Mall identification messages.” The campaign leverages Sizma Rei’s unique talent for identifying specific AEON Mall locations from partial photos of facilities. Participants purchase a drink at Kajitsu Kobo Karin, then post a photo of their juice along with a shot of the AEON Mall interior on X with the hashtag #イオンモールの果琳で給水.

Sizma Rei manually responds to posts every day. As of early July, the hashtag has accumulated roughly 3,000 posts. Fans have been posting challenges like “Can you identify this one, Sizma Rei?” and even the official AEON Mall account has joined in by sending challenges, fueling a lively online exchange.

July and August Collab Drinks

The July collab drink is “Sparkling Orange & Lemon,” while August features “Gulping Grapefruit & Lemon” — both refreshing citrus offerings perfect for summer. Sizma Rei was personally involved in developing these special menu items, which are served in collaboration-exclusive cups. Each qualifying purchase earns a limited sticker (1 of 5 random designs), and an original card giveaway is also available with the purchase of a “Pure Watermelon Juice Ticket Book.”

Looking Ahead

The campaign is set to continue through the end of August, with the August limited collab drink “Gulping Grapefruit & Lemon” still to come. The expanded 92-store format will make the campaign accessible to fans in regions that were previously outside the coverage area. When the campaign launched in June, it covered 85 stores, and the steady expansion reflects its strong reception. The X posting campaign will also continue, with even greater activity expected as summer vacation season approaches.

Analysis

While VTuber collaborations with food brands are not uncommon, this campaign stands out for centering the concept around Sizma Rei’s signature “AEON Mall identification” content. The interactive format — where fans voluntarily post with the hashtag and Sizma Rei manually responds — has generated some 3,000 posts, representing a compelling new success pattern for VTuber collaborations. The expansion from 85 to 92 stores is a concrete result that could serve as a model for future VTuber x physical retail partnerships.
