### "Drink, and Get Stronger." The Taste of Karasuno's Youth Becomes a Daily Supporting Drink.
A collaboration protein between the anime "Haikyuu!!" and "be LEGEND Sports & Wellness" is here! The package features the Karasuno High School Volleyball Club!
This time, be LEGEND has created "Gungun Banana", which can be called the "taste of Karasuno High School's youth." In the world of the anime "Haikyuu!!", there is a "Gungun Series" that students drink during breaks, and it is depicted as a familiar presence for the members of the Karasuno High School Volleyball Club.
In this collaboration, that "Gungun Banana" has been commercialized as a protein. This product was born from the desire to deliver "that one drink" that was part of Karasuno's daily life as nutritional support for people striving every day.
Furthermore, the message "Drink, and Get Stronger." embodies the importance of eating, getting nutrition, and consistent effort, as depicted in the anime "Haikyuu!!", wishing to provide it as a daily supporting drink.
### Protein Designed to Reflect the "Importance of Nutritional Intake" Depicted in Anime "Haikyuu!!"
This product is not just a collaboration item that allows you to enjoy the world of the anime "Haikyuu!!".
"Haikyuu!!" is not just a work that depicts matches; it is a work that also depicts the importance of eating, taking in nutrients, building a body, and the "foundation" that supports daily practice.
Coach Ukai of the Karasuno High School Volleyball Club, who appears in the work, told the players, "So eat proper meals," conveying the importance of daily meals and nutritional intake, not just practice.
This protein product has placed such teachings at the center of its product development.
To give form to that idea, this collaboration adopts the "Sports & Wellness" series from be LEGEND. "Sports & Wellness" is a series developed to support those engaged in club activities and sports, providing 15g of protein and energy equivalent to one banana per serving.
Protein is the building material for the body. Energy (carbohydrates) is the fuel for movement and recovery. This drink allows for easy replenishment of both, not just one.
Furthermore, it contains maltodextrin, a fast-absorbing energy source. It is designed to be easily incorporated into nutritional intake before and after games or practice, as well as for busy mornings.
Enjoy the taste of Karasuno's youth while supporting those who are working hard with nutrition. This protein is finished in a style typical of the anime "Haikyuu!!", embodying "Drink, and Get Stronger."
