Aimer《太陽が昇らない世界》是劇場版《鬼滅の刃 無限城編 第一章 猗窩座再來》的主題曲，由近藤光作詞、椎名豪作曲與宮野幸子共同編曲。歌曲以莊嚴的交響樂編制結合Aimer極具穿透力的歌聲，描繪面對壓倒性黑暗與恐懼時的勇氣與決心。旋律在小調與和聲小調間流轉，營造出悲壯與希望並存的氛圍，副歌的高昂情感與全樂團爆發更將故事的緊張感推至高潮，完美呼應劇情中關鍵的激烈對決與不屈精神。

Aimer’s “World Where the Sun Never Rises” serves as the theme song for Demon Slayer: Kimetsu no Yaiba – Infinity Castle Arc Part 1: Akaza’s Return. Written by Hikaru Kondo, composed by Go Shiina, and co-arranged with Sachiko Miyano, the track blends majestic orchestral arrangements with Aimer’s emotive, powerful vocals. Shifting between natural and harmonic minor scales, the song creates a poignant balance of sorrow and hope. The soaring chorus, backed by a full orchestra, mirrors the film’s intense battle scenes, while dynamic contrasts reflect the characters’ emotional journey from despair to resolve.
