## Background and release

Yoasobi released their first two extended plays in 2021—The Book and The Book 2—with the concept of a "reading CD" with a binder package. The EPs peaked at number two on the Oricon Albums Chart, In 2021, the duo collaborated with Naoki Prize-winning four novelists Rio Shimamoto, Mizuki Tsujimura, Miyuki Miyabe, and Eto Mori for the short story collection Hajimete no, published in March 2022. It inspired four songs "Mr.", "Suki da", "Umi no Manimani", and "Seventeen", which were included on a companion EP. Apart from the project, the duo released the theme song for Universal Studios Japan's 2023 Unibaru campaign "Adventure", and two anime series opening themes: "Shukufuku" for Mobile Suit Gundam: The Witch from Mercury and "Idol" for Oshi no Ko, which the latter became the duo's most successful song to date in both Japan and overseas.
On September 1, 2023, Yoasobi announced their third extended play, titled The Book 3, alongside its track list and album cover, set to be released on October 4. Pre-orders of the EP began on the same day, being made available only as a limited-edition binder package. The Book 3 consists of all singles from 2022 to then-recent September 2023, including all songs from Hajimete no – EP; and three new tracks, which two are interludes "Awakening" and "Worship", intros for "Shukufuku" and "Idol", respectively, and another is an opening theme for anime series Frieren: Beyond Journey's End, titled "Yūsha", which was announced the same day as the EP via a promotional video of the anime. The song was released as a single ahead of the EP on September 29. The Book 3's trailer was uploaded on October 1. A year later, in 2024, the vinyl record format was released elsewhere by Sony Music Germany and Black Screen Records on July 26, and in Japan with the different cover artwork illustrated by Qingyi on October 23.

## Music and lyrics

The Book 3 is an electropop and synth-pop record, and contains ten tracks. The opening track "Yūsha" incorporated the Frieren titular character's emotional changes and memories towards the hero Himmel. Despite funky and upbeat music, it expresses the lonely and melancholy atmosphere of the anime. "Shukufuku" narrates perspective from Mobile Suit Gundam: The Witch from Mercury's character XVX-016 Gundam Aerial to its host Suletta Mercury to fight alongside her and watch her lead-up to the events of the anime. "Umi no Manimani" talks about a girl who runs away from home and gets off at a train station by the sea at night, and she is called out to by a mysterious girl. Described as a "painfully ephemeral" city pop track, "Mr." is about the desire of an android towards their owner.
A combination of Japanese idol-styled pop, hip-hop, rock, and video game music, "Idol" depicts the two-faced nature of idols in the entertainment industry via various perspectives on Oshi no Ko's character Ai Hoshino from her fans, her groupmates, and herself. It is followed by "Seventeen", expressing a 17-year-old girl who decided to bid farewell to the world she lived in and her parents to save the crisis in the parallel world. "Adventure" is described as "a bright and refreshing spring-like song packed with fun memories at the [Universal Studios Japan] park." The Book 3 concluded with "Suki da", telling the protagonist's fourth attempt to confess her crush, who is her childhood friend while struggling across space and time to erase her past love confessions.
