Second Collaboration with Nijisanji's Rito Usami and Ittetsu Saiki! Limited-Time 'Fine Protein Diet' Special Sets on Rakuten Ichiba

Fine Inc. (Headquarters: Yodogawa-ku, Osaka; Representative Director: Nobutsuna Sasaki), a manufacturer and seller of health foods and pharmaceuticals, is launching its second collaboration with the VTuber/Virtual Liver group 'Nijisanji.' Following the first campaign, which sold 8,000 units and caused temporary stock shortages, this second installment features Rito Usami and Ittetsu Saiki. The special sets, titled 'Hero Ritotetsu Ultra Recommended Set,' 'Rito Usami Recommended Set,' and 'Ittetsu Saiki Recommended Set,' will be available exclusively on Rakuten Ichiba from May 28, 2026, at 11:00 AM to June 11, 2026, at 11:59 PM.

This project follows the successful '#NijiFine' collaboration. Once again, Oriens members Rito Usami and Ittetsu Saiki have been selected to curate flavor sets. To encourage beginners to maintain their protein intake, the sets are offered at a special price, up to 47% off the regular price.

Additionally, a commemorative stream will be held on Rito Usami's YouTube channel on June 5 (Friday). This time, the stream will feature 'Niji 3D' technology for more realistic and three-dimensional movement. The stream will include product introductions, body-making tips, and workout/stretch segments to showcase the appeal of the Fine Protein Diet. A special interactive segment for those who purchased the products before the stream is also planned.
