Lagu "Kasumi" yang dibawakan oleh Eir Aoi menceritakan tentang kesepian, kesedihan, dan kerinduan yang mendalam. Liriknya yang puitis mengeksplorasi perjuangan pribadi seorang individu yang merasa terasing dan merindukan seseorang yang dapat mengisi kekosongan dalam hatinya. Saat mereka merenungkan masa lalu dan saat-saat kerentanan, mereka menemukan penghiburan dalam kenangan akan suara orang yang mereka cintai, yang menggema melalui kegelapan dan memberikan secercah harapan.
Kasumi Lyrics
Eir Aoi
Fukai chinmoku dorekurai tsudzuitarou
Terebi no oto ga yakeni ookiku kikoeru
Donna kotoba wo zutto matteiruno?
Chiisana heya ga hiroku omoeta
Sabishisa setsunasa to aigokoro
Irimajitta nodo no okusoko
Tatta no suubyou no mugon ni kakikesareteshimau
Itsuka no
Girigiridatta yoru mo kokoro ga oresouna toki mo
Jibun sagashite naita
Makkura kuragari no fukai fukai yami no naka de
Kimi no koe ga kikoeta
Sonna koto omoidashite koboreta namida no saki ni
Donna koto omou no kana nante chotto hibikikaketa
Yappa zutto motto
Kimi omou no
Kono mama kitto surechigai tsudzukeru no
Terebi no oto wa watashi dake ni kikoeteru
Fui ni nagareta ano hi no omoide
Watashi hitori de nagameteta
Namida to kanashisa to aigokoro
Itsu made mo konjiru koto no nai
Katahou no kimochi wo mune no oku gyutto oshikonda
Sou yatte
Girigiridatta yoru mo kokoro ga oresouna toki mo
Jibun ga nakute naita
Makkura kuragari no fukai fukai yami ni
Kimi no koe wo sagashita
Sonna koto omoidashite koboreta namida wo kimi wa
Donna fuu ni miteru no kana nante
Chotto kitai shite wa zutto tooku ni kimi, omou no?
Shikou ga meguri ni megutte sono uchi yuhi ni kawatta
Kangaeru hodo ni
Kimi he no omoi wa ima mo kawaru koto no nai mama
Mune wo shimetsuketeiku itsuka wakariaetanara
Sabishisa setsunasa to aigokoro
Irimajitta nodo no okusoko
Tatta no suubyou no mugon ni kakikesareteshimau
