Somewhere in Japan, a marketing executive looked at Street Fighter II, a giant cheeseburger, and a parody version of one of the country’s most legendary rock bands and thought, “You know what this needs? A secret fighter.” And honestly, I would like to shake that person’s hand.
McDonald’s Japan has released a wonderfully bizarre new crossover video featuring LUNA CHEE joining the world of Street Fighter II. Announced on the company’s official X account with the message “Luna Chee joins Street Fighter II!”, the clip brings the fast-food chain’s two very different pop-culture promotions together in a pixelated arcade showdown. If you ever wondered what would happen if a Japanese visual-kei rock band wandered into an old-school Capcom fighting game, apparently, McDonald’s has an answer.
The character comes from LUNA CHEE, a parody tribute project based on the legendary Japanese rock band LUNA SEA. The name is a cheesy little play on LUNA SEA, and the whole thing was created to promote McDonald’s Japan’s limited-time cheese-heavy menu. It is an officially approved copy band, and the joke has grown considerably since its first appearance in 2025.
The original LUNA CHEE commercial featured actor Seishiro Kato as the band’s flamboyant lead vocalist, styled to resemble LUNA SEA frontman RYUICHI. The actual singing was handled by impressionist tam tam, whose performance paid tribute to RYUICHI’s distinctive vocals. The commercial reworked LUNA SEA’s 1994 hit “ROSIER” with lyrics inspired by McDonald’s cheese burgers, while recreating the dramatic look and feel of the original music video. It’s the sort of thing that sounds completely ridiculous until you actually watch it.
And McDonald’s wasn’t finished with the joke. For its 2026 campaign, LUNA CHEE returned with a much bigger musical operation. The company assembled 100 musicians representing 19 bands for a massive performance inspired by “ROSIER.” The roster includes familiar names from Japan’s visual-kei scene, including YOMI of NIGHTMARE, Reo of lynch., and musicians associated with vistlip and DEZERT. HIROTO of Alice Nine, HARUTO of LUNA RIVER, Yue of KIZU, and Hibiki of Matenrou Opera are also among the performers.
Kato returned as the on-screen lead vocalist, with tam tam back in the mix. Even LUNA SEA’s own bassist J showed up at the recording session to surprise the musicians and offer some encouragement. That’s quite a moment for a commercial band that started as a joke about cheese.
The food behind the musical madness is McDonald’s Japan’s seasonal “Chee Chee” menu. The 2026 lineup includes the Chee Chee Double Cheeseburger, the Chee Chee Teriyaki McBurger, and a new Chee Chee Teriyaki Chicken Juicy Mac. There’s also a breakfast-only Chee Chee Double Cheeseburger Sausage Muffin. The limited-time menu went on sale November 4 and is scheduled to run through November4, 2026.
But LUNA CHEE’s appearance in Street Fighter II has another layer of fast-food history behind it. McDonald’s Japan previously teamed up with Capcom for its first-ever Street Fighter menu collaboration in October 2025. Called Street Burgers, the promotion gave Ryu, Chun-Li, and Ken their own character-inspired sandwiches.
Ryu received a Burnt Garlic Mayo Egg Teriyaki Burger, Chun-Li got a Yurinchi Mayo Chicken sandwich, and Ken was represented by the towering Triple Cheeseburger, also known as the Torichi. The campaign even included special drinks, limited-edition packaging, and a series of commercials animated in the nostalgic style of Street Fighter II. Those ads featured the familiar fighters facing off against McDonald’s-inspired opponents, including the wonderfully named Vega Smile.
The 2025 promotion also reached into Street Fighter 6, where players could receive a special M. Bison costume color as part of the collaboration. So McDonald’s has already demonstrated that it is perfectly comfortable treating Capcom’s fighting-game universe as an extension of its advertising playground.
Now the two campaigns have collided. LUNA CHEE gets to join the pixelated fighting-game fun, giving McDonald’s another opportunity to show off its affection for Japanese music and gaming nostalgia. It’s a pretty spectacular place for a parody rock band to end up, especially one that was originally assembled to sell extra cheese.
McDonald’s Japan has a knack for turning an ordinary menu promotion into something that feels like an event from an alternate pop-culture universe. And while we may never get to select LUNA CHEE on the character screen of an actual Street Fighter game, this crossover is a pretty entertaining consolation prize. Somebody get this band a finishing move. Preferably one involving melted cheese.
