Haikyuu!! and be LEGEND Launch Second Collaboration Protein with Gungun Yogurt Flavor and Character Stickers

The popular anime series Haikyuu!! has announced its second collaboration with the protein brand be LEGEND. The new product, be LEGEND WPC Haikyuu!! Gungun Yogurt Flavor, will go on sale starting July 16, 2026, at 12:00 JST through the be LEGEND official online store, Amazon, Rakuten Market, and Yahoo Shopping.

Inspired by Kageyama’s Favorite Drink

The flavor of this protein powder is inspired by the “Gungun Yogurt” that Kageyama Tobio is seen drinking during his breaks in the series. With a gentle sweetness, it is recommended even for protein beginners. Each serving (approximately 20g) contains 10g of protein, along with 0.24mg of iron, 400mg of calcium, 40mg of vitamin C, and 4.0μg of vitamin D—making it a convenient way to supplement daily nutrition whether as a post-workout drink, a breakfast companion, an afternoon snack, or a dessert after dinner.

Special Packaging and Stickers

The package features an illustration of Hinata Shouyou and Kageyama Tobio, with Kageyama setting the ball and Hinata spiking. The design is exclusive to this collaboration and is meant to be enjoyed both as a display piece and as a functional protein container.

Customers who purchase the first production batch from the be LEGEND official online store will receive a random sticker from a set of six. The stickers are waterproof and can be attached to shaker bottles. The six characters depicted are Hinata Shouyou, Kageyama Tobio, Oikawa Tooru, Iwaizumi Hajime, Kozume Kenma, and Kuroo Tetsurou. One sticker is included per bag of protein.

Protein Textbook Returns

Following the first collaboration, this second wave also includes a “Protein Textbook”—a booklet packed with knowledge about protein and tips for making it taste better. The design is different from the previous version, and this bonus is available not only at the official store but also at Amazon, Rakuten Market, and Yahoo Shopping.
