The Book 3

The Book 3 is the third Japanese-language EP (sixth overall) by Japanese duo Yoasobi. It was released on October 4, 2023, through Sony Music Entertainment Japan, one year and ten months after their second EP The Book 2 (2021). Continuing with the "reading CD" concept as previous records, the EP spans electropop and synth-pop genres, comprising ten tracks, which were solely written and produced by one half of the duo Ayase. Eight singles preceded The Book 3, including top-five anime opening theme songs: Mobile Suit Gundam: The Witch from Mercury's "Shukufuku", Oshi no Ko's "Idol", and Frieren: Beyond Journey's End's "Yūsha". Commercially, The Book 3 peaked at number two on both the Oricon Albums Chart and Billboard Japan Hot Albums, and was certified gold by the Recording Industry Association of Japan (RIAJ) for shipments of over 100,000 units. The EP won Finalist Award (Red) at the 16th CD Shop Awards.
