In addition to his solo releases as a Vocaloid producer, his self-cover songs have also garnered high praise, with his self-cover of “Yorunaderu Menou” surpassing 70 million views on YouTube. Furthermore, in 2023, he released the collaborative track “Hiten,” featuring R-Shitei (Creepy Nuts). This long-awaited collaboration, with Ayase singing as part of YOASOBI, is a special song that encapsulates YOASOBI’s current state. Please look forward to the broadcast of the drama “If This World Were a Stage, Where Would the Dressing Room Be?” and the theme song “Gekijo.” ■Song information
