The first season of the anime version, “Tanjiro Kamado: Unwavering Resolve Arc”, aired on TV in 2019. By 2024, “Infinity Train Arc,” “Entertainment District Arc,” “Swordsmith Village Arc,” and “Hashira Training Arc” had been produced. “Infinity Castle Arc” will be adapted into a three-part animated film about the final battle that takes place in the demons’ home base, “Infinity Castle.” “Chapter 1: Akaza Returns,” which was released on July 18, was a mega-hit, drawing in 5.16 million viewers and earning 7.31 billion yen in box office revenue in the first four days after its release.

Aimer and LiSA are female singers who have been in charge of the theme songs for the Demon Slayer series so far. In Aimer’s music video for “A World Where the Sun Doesn’t Rise,” a marching band of over 70 people appears, led by a dancing conductor. The fusion of music and dance expresses the song’s mysterious worldview. In the music video for “Shine in a Cruel Night,” LiSA’s own performance and CG expressions that change according to her emotions decorate the epic song that lasts over six minutes.
The music videos for both songs are included on the Blu-ray included with the single CD (limited edition) released on July 23rd.

Each costs 1,760 yen.
The full comments from Aimer and LiSA are as follows:
[Aimer]

The unconventional world of this song has been captured in the video in a simple yet detailed way. Just like the song, the resulting music video is divine and grandiose, sad and disturbing, and addictive. Please come and witness and experience the strange energy, dynamism, and sense of unity that comes through on screen.
[LiSA]

I poured my soul into this song, as if I was being led by it and at times almost being swallowed up by it, as it unfolds in various ways. When I watched the completed music video, I was so captivated that I forgot to breathe. The transience, beauty, strength, and suffering of the song are all more apparent in these 6 and a half minutes. I hope you enjoy it.
