Only famous artists! Anime songs that energize the Reiwa era

When it comes to anime songs, in the Showa era there were many child-oriented tracks made specifically for each anime, while in the Heisei era there were many tie-in songs that often had little to do with the anime’s storyline.

In contrast, these days there are more and more songs written for anime that have also become signature hits for the artists themselves.

This may well be because Japanese anime has gained popularity overseas.

So this time, we’ll be introducing songs that serve as theme songs for some of Japan’s most iconic anime works!

Only famous artists! Anime songs that enliven the Reiwa era (41–50)

The lines depicting a love that overflows beyond logic bring back the moment you first fell for someone.

This is a song by Aimer, written as the theme for the anime film Demon Slayer: Kimetsu no Yaiba – Infinity Castle Arc Part 1: Akaza Returns.

The dual-theme arrangement with LiSA also drew attention.

The song portrays a steadfast will and heartfelt prayer to keep fighting for what one wants to protect, even in a lightless, desperate situation.

Aimer’s uniquely resonant vocals intertwine with the sweeping strings to grip the listener’s heart.

Protect the Lightsupittsu

Released in October 2025 as a digital single—the first in about two and a half years—it serves as the opening theme for the TV anime SPY×FAMILY Season 3.

Masamune Kusano commented, “While it’s a work whose comical and cute depictions are fun, I wanted the song to face the sorrow that flows at the root of the story rather than run from it,” and true to his words, the sound beautifully captures a world where poignancy and hope intersect.

The rich arrangement, co-produced with Seiji Kameda, is also a highlight, with horn sections and organ adding vivid color.

It gently gives a push to the courage to protect what matters most.
