Aqua Terrarium / アクアテラリウム (OST Nagi no Asukara Ending ED)
Romaji Lyrics:
Atata kai mizu ni oyogu detoritasu Nagai jikan wo kakete ito wo tsumugi nagara Mayu ni naru…
Ittai dore kurai mabuta wo tojite itan darou Matte mo matte mo bokura zutto futari kiri Koko wa yuugen no suisou de Namae wo yobeba awa ni naru
Atata kai mizu ni oyogu detoritasu Nagai jikan wo kakete ito wo tsumugi nagara Odayaka ni nemuru kimi no soto gawa de Subete no kanjou kara mamoru mayu ni naru
English Translation:
The detritus is swimming in the warm water Spinning the threads for a long, long time To form a cocoon…
How long have my eyes been closed? Even if we keep waiting, the two of us will always be alone This is an aquarium with boundaries If someone’s name is called, he will turn into bubbles
The detritus is swimming in the warm water Spinning the threads for a long, long time As you sleep peacefully, it will protect all your feelings From the outside, where it forms a cocoon
