The official website for the upcoming TV anime A Tale of the Secret Saint announced its opening and ending theme song artists today. Japanese female singer Kaya sings the opening theme song "Flare of Soul." She made her major debut in January 2022 and has also performed as HiREN in EARTH STAR Entertainment's multimedia project Utahime Dream. As a solo singer, she has provided the opening theme "Reincarnation" for the ongoing fall 2025 TV anime Hero Without a Class , and will also sing the ending theme "Sanctuary" for the upcoming winter 2026 TV anime Hell Mode . Comment from Kaya: I am Kaya, and I will sing the opening theme song. The opening theme, "Flare of Soul," is a song that depicts the heart that lives straight, gentle, and strong like Fia, even while resisting the fate that has been given. Choosing the path one believes in over what is considered right, and continuing to walk it — I sang with that sentiment in mind. The strength to keep moving forward, even while carrying doubts and pain. The impulse to seize the answer chosen not by reason, but by the heart. I pour all of that into my voice. I hope this song, alongside the anime, can become something that stays close to your hearts and gently pushes you forward.

Comment from Rena Yamasaki (the voice of Ibuki Yumesaki): It has been decided that Utahime Dream Allstars will perform the ending theme song for the TV anime "A Tale of the Secret Saint." I'm truly delighted to have this opportunity as Allstars again. The lyrics, which resonate deeply with the work, are absolutely wonderful. I feel they capture a different vibe for UtaHime compared to before. I sincerely hope many people will listen to this song, sung powerfully by Allstars.
