Background and release
Starting on September 2, 2022, Yoasobi uploaded three mysterious images of the unknown black shape with a white background featuring the text "941", "730", and "Coming Soon!!!" for three days. Two days later, the second promotional video of the Japanese mecha anime series Mobile Suit Gundam: The Witch from Mercury was announced, revealing that Yoasobi would be handling its opening theme "Shukufuku". The song was based on Yurikago no Hoshi (ゆりかごの星), a short story written by Ichirō Ōkouchi, who is also in charge of writing the anime. The story was published on the anime's official website on October 2.

The anime edit version of "Shukufuku" was unveiled on September 16 on the special radio show All Night Nippon Music Week, which the duo hosted for one night only to commemorate the 55th anniversary of All Night Nippon. The digital cover artwork was unveiled on September 25. The song was available for digital music and streaming platforms on October 1, one day before the anime's first episode premiere. The music video, directed by Nobutaka Yoda with animation direction by Yutaro Kubo, premiered via the duo's YouTube channel the next day. It portrays the same visuals as the anime but is "warmer" than the main theme.

A limited CD single of "Shukufuku" was subsequently issued on December 9, including the English version titled "The Blessing", the anime edit version, and the instrumental version, its based novel, original Gunpla Demi-Trainer, and XVX-016 Gundam Aerial decal in an exclusive collaboration with the duo. Yoasobi shared the snippet of the song recorded the English on November 3 after the music video surpassed 10 million views. The English version was released digitally as a standalone single on the same day as the CD single, and included on the duo's second English-language EP E-Side 2, released on November 18. The anime edit version later featured on the soundtrack album to the anime, while the full version appeared on the duo's third EP The Book 3, released on October 4, 2023.

Composition and reception
"Shukufuku" is a electropop and dance-pop song with "catchy" melodies and "throbbing" beats, written and produced by Ayase, a duo member. It depicts the relationship between the main protagonists Suletta Mercury and her XVX-016 Gundam Aerial, narrated from the perspective of the Gundam, fighting alongside their host and watching her lead-up to the events of the anime and reminding "the adherence to and liberation from oppression." It was composed in the key of E minor, 170 beats per minute with a running time of three minutes and 16 seconds.

Real Sound's Tsuki no Hito described the composition of "Shukufuku" that "the piano sound is gorgeous, and the arrangement is full of sprinting, but the uneasiness hidden throughout the phrase has a thrilling feel suitable for Gundam works with many battle scenes," while said that "the sound image [of "Shukufuku"] coexists suppleness, beauty, and strength, highlighting the world view of The Witch from Mercury while vividly demonstrating Yoasobi's innovation." Nahda Nabiilah from Game Rant praised the song as "providing an upbeat tune that can raise the listener's energy and build up their enthusiasm to start the anime episodes." Writing for Rockin'On Japan, Fumiaki Amano compared "Shukufuku" that "may be as close as possible to what lies between Ayase and Ikura", likening "Yoasobi's theme song".
