Japanese musical duo YOASOBI will extend the excitement of the Overwatch World Cup through music at BlizzCon 2026. YOASOBI is set to perform at BlizzCon's first-ever esports halftime show during the tournament, featuring their Overwatch collaboration song "Orion" among other tracks. Their signature approach of adapting stories into music extends this time to the game's world, gameplay experience, and a stage set for esports fans gathered from around the world.
"Orion" is a song built on the Overwatch short story "The Fall of a Sparrow." Set against the backdrop of Tokyo, it explores the intertwined memories and relationships of Kiriko, Genji, and Hanzo. Through the collaboration between Overwatch and YOASOBI held last July, the song expanded into various in-game content, including an animated music video and legendary skins. That collaboration highlighted the journey of the three characters reuniting through distance, loss, and longstanding conflict, all seen through Kiriko's eyes.
YOASOBI explained that their approach to game music differed from working on anime theme songs. Rather than focusing on following a narrative, they felt they needed to stimulate and accelerate the active gameplay experience of the players. Ayase emphasized more pop and fun elements than usual, while ikura enhanced the depth of her vocals so that listeners could feel a stronger connection and affection for the three characters. For the cyber and near-futuristic imagery of the Tokyo map, they incorporated the timbre of the koto—a traditional Japanese string instrument—combining Overwatch's vision of Japanese culture with YOASOBI's J-pop in a single track.
The interview also revealed YOASOBI's approach toward the global market. They explained that rather than intentionally mixing in Western elements for overseas listeners, presenting their J-pop as it is was embraced as something fresh. They also pointed out J-pop's strength in having fluid genre boundaries, allowing it to merge flexibly with various cultural mediums such as video games, manga, and anime.
YOASOBI described this collaboration with Blizzard and Overwatch as a milestone project for them. On the BlizzCon stage, they aim to show a side of themselves never seen before alongside newly discovered sounds from the collaboration, while also delivering music that is unmistakably YOASOBI. They emphasized their determination to amplify the love and energy that players and fans hold for Overwatch through their performance.
YOASOBI's music has shown strong synergy with narrative-driven works like anime and games. When creating "Orion" based on the Overwatch short story "The Fall of a Sparrow," how did your approach differ from an anime theme song? How did you express the emotions and bonds of Genji, Hanzo, and Kiriko in the music?
" Ayase: We thought about how to approach this differently compared to anime theme songs where a narrative unfolds. For a game, we felt the music needed to stimulate the player's active experience and elevate excitement and a sense of speed. So we tried to incorporate slightly more pop and enjoyable elements than usual into the song.
ikura: I wanted to express the story and bond of the three characters through vocals as well. I sang with deeper vocal nuance so that players wouldn't just play the game, but feel a greater sense of attachment and interest in these characters, drawing closer to them with affection.
What was most memorable when you first received the collaboration proposal? Also, what would you say is the biggest charm of the completed "Orion"?
" ikura: When I first heard about it, I was thrilled and surprised. Overwatch is beloved worldwide, and since this project centered around the Tokyo map, I was especially delighted that they invited us as collaboration artists.
As we recorded the vocals and contemplated what we could create as YOASOBI, we discovered new sounds and vocal expressions that only came to life because of this collaboration with Overwatch. It was a process where I discovered a new dimension within myself, and I think that's the true charm of "Orion."
Which Overwatch hero impressed or inspired each of you the most? From the perspective of Japanese creators, how did you feel about how Japanese culture was interpreted through Genji, Hanzo, and Kiriko?
" Ayase: The characters we focused on for this song and the Tokyo map were Kiriko, Genji, and Hanzo. In particular, after reading the short story deeply and writing the lyrics, I came to feel a strong attachment to Kiriko.
I could understand what aspects of Japanese culture overseas creators find cool. While it might differ from a literal depiction of traditional Japan, even through Japanese eyes, it looked fantastic. They added cyber and near-futuristic elements to Japanese culture while naturally incorporating traditional music elements like the sound of the koto.
When writing the song, I reflected this direction as well. Combining futuristic sounds with the koto's tone allowed listeners to enjoy the music in a more multi-dimensional way. I felt that through this fusion, we could share the appeal of J-pop and Japanese culture more broadly with the world.
How do you resonate with fans from diverse cultural backgrounds while preserving the unique flavor of YOASOBI and J-pop? What do you consider the biggest strength of J-pop in the global music market?
" Ayase: We don't intentionally blend in Western musical elements just to appeal overseas. Presenting songs born as J-pop exactly as J-pop is actually received as something fresh, and I feel the number of people who appreciate that is steadily growing.
J-pop doesn't have its roots fixed to a single form; it possesses flexibility and uniqueness that allow it to transform into anything. That's why it can fuse three-dimensionally with games like Overwatch, as well as manga, anime, and various other cultures. I believe there is still immense potential to spread the appeal of J-pop worldwide through Japanese culture as a whole.
How do you feel about performing at BlizzCon, where Blizzard fans from around the world gather? Could you introduce any special performances prepared for gamers and esports fans?
" ikura: I never expected we would stand on a stage where people from all over the world gather, so I'm thrilled. It will be a performance made possible because of our collaboration with Overwatch, and I think we'll be able to show a side of YOASOBI that hasn't been seen before.
At the same time, we believe it's important to express who we are as artists beyond the framework of J-pop. I hope everyone looks forward to both aspects. As this is a key halftime show, we will do our best to amplify the love and energy that the players and attending fans hold for Overwatch through YOASOBI's performance.
Do you have any final words for fans from Asian countries visiting BlizzCon?
" YOASOBI: We want to share this message not only with Asian fans, but with all Overwatch fans worldwide. Creating "Orion" together with Blizzard and the Overwatch team was a deeply meaningful project that served as an important milestone for us. We'll pour everything into our stage performance, so please look forward to it.
