Opening Theme Song
"Enja" by 4s4ki
Lyrics: 4s4ki
Composition/Arrangement: 4s4ki/NUU$HI
Message from the artist
This is 4s4ki, and I had the pleasure of creating the opening theme.
As a huge anime fan, I had a lot of fun creating the music!
For this song, I incorporated the story, morality, and characters' emotions from "New Saga" into the lyrics, while also projecting myself as an "actor" portraying these anime characters.
I'm super hyped for the anime, and we really put a lot into the sound and melodies. So, I hope you can feel the speed, and the characters' strong will and sense of mission while listening for all the little details!
The whole process was incredibly fun!
Everyone, make sure to watch it!!!

Ending Theme Song
"her" by Mahiru Coda
Lyrics: Mahiru Coda
Composition: Mahiru Coda / Yoichiro Nomura
Arrangement: Yoichiro Nomura
Message from the artist
I'm Mahiru Coda, and I'm honored to be in charge of the ending theme.
While reading the original work, I was drawn into the unique and exciting elements of this series. While we tend to focus on the main characters' strong drive towards their goal, I realized that the interactions with the women around them are also an essential part of the story. So, I decided to depict their love triangle from a female perspective.
The meaning behind the title "her" is part of a poignant story that will spark your imagination. I hope that when you listen to the song, you'll feel as if you've been transported into the world of the anime.
