A collaboration between the TV anime “Haikyū!!” and Mos Burger will run from November 4, 2026, to January 11, 2027, and a newly drawn visual featuring seven players from Karasuno, Otonokoma, and Fukurodani Academy tucking into Mos Burger has been unveiled. Special online pre-orders for the “2027 Mos Burger Lucky Bag”—which includes four limited-edition items and 5,000 yen worth of meal vouchers (starting November 25 at 3:00 PM)—will be available, along with freebies with the Mos Wai Wai Set and an original in-store voice message from Shoyo Hinata.
