Tempalay Performs Fool Night’s Opening Theme “Shake! spit out”
The opening theme, titled “Shake! spit out”, will be performed by Japanese band Tempalay.
According to the band, the song was inspired by a Shakespeare passage featured at the beginning of Fool Night. The group also explained how the series’ themes of despair, survival, contradictions, and escapism influenced its musical approach.
Tempalay shared the following comment:
“The idea for this song came from the Shakespeare passage used in the beginning of “Fool Night.” Using the series’ theme of finding light in the midst of despair, we believe we were able to capture the thirst for life, the contradictions and the escapism. We incorporated as much of the story as possible in our own way, so please enjoy it in conjunction not just with the anime, but also with the manga.”
The comment highlights how the band approached the series beyond simply creating an opening song, incorporating its underlying themes and atmosphere into the music.
Nowlu Shares Emotional Message About Fool Night’s Ending Theme “Iki”
The ending theme, “Iki” (息), performed by Nowlu, is another major musical highlight of the announcement.
The song was written specifically for the anime, and Nowlu revealed that the story’s realistic social issues and emotional conflicts strongly resonated with her own experiences while writing it.
Her comment is particularly personal, connecting the protagonist’s struggles with her own feelings and expressing gratitude for being able to give life to the song.
Nowlu shared the following message:
“「息」 This is nonfiction. It’s a cry from Toshiro and me.
This series instantly drew me in with its realistic societal backdrop and issues and the many situations that feel like they could truly happen.
The pain, grief and anger so closely resembled what I was dealing with when I wrote this song that I even thought it was fate that I was meant to write it.
I think the lyrics took on a sensibility that only I could express.
I’m truly happy that I encountered a series and a song that set my heart on fire, and that I was able to breathe life into the lyrics.
I’m glad I’m alive.
Please keep on living, too.”
Nowlu’s closing words are particularly meaningful alongside a story that explores survival, despair, and the value of human life in a world where people must make extraordinary sacrifices simply to keep living.
What Is Fool Night About?
Fool Night is a supernatural science-fiction manga written and illustrated by Kasumi Yasuda, serialised in Shogakukan’s Big Comic Superior magazine.
The story takes place in a distant future where thick clouds have covered the sky for a century, blocking sunlight and leaving Earth in a seemingly endless winter. Most of the planet’s vegetation has withered away, creating a severe oxygen shortage that threatens humanity’s survival.
To address the crisis, society develops Transfloration, a technology that implants seeds into the bodies of people nearing death and transforms them into plants capable of producing oxygen.
The transformed humans are called Spiriflora, and their existence has become an essential part of the world’s survival.
The story follows Toshiro Kamiya, a young man living in poverty who struggles to support himself and pay for his mentally ill mother’s treatment. With little hope left in his life, he eventually chooses the path of becoming a Spiriflor.
After undergoing the procedure, Toshiro gains an unusual ability to hear the voices of people who have been transformed into plants.
He is subsequently employed by Transflora Medical as a special temporary worker, using this ability to assist with investigations.
However, when a series of murders involving Spiriflora begins, Toshiro becomes involved in an increasingly complicated mystery that reveals darker aspects of the society he inhabits.
The series explores the value of human life, social inequality, sacrifice, and the difficult choices people make when survival becomes their greatest concern.
SUNRISE and SHAFT Collaborate on Their First Joint Anime Production
One of the biggest production highlights of Fool Night is the collaboration between SUNRISE and SHAFT, two established Japanese animation studios.
SUNRISE is known for major anime franchises such as Mobile Suit Gundam, Cowboy Bebop, and Mobile Suit Gundam: The Witch from Mercury. SHAFT, meanwhile, is recognised for its distinctive visual direction in works including Puella Magi Madoka Magica and the Monogatari series.
