In the near future, much of the world has been forgotten at the bottom of the ocean due to rising sea levels. Natsuki Ikaruga, who lives in a small town surrounded and stranded by the sea, is invited by a mysterious woman, Catherine, to search for a treasure in his grandmother's house who was a marine geologist. One day, he dives to the bottom of the ocean in a submarine and encounters a mysterious capsule with a girl sleeping inside. The girl was a humanoid so sophisticated that she could be mistaken for a human.
And here I thought you finally disappeared.
وأنا الّتي ظننتُكِ قد اختفيتِ أخيراً
Es ist nur … Er hat sich schon
so lange nicht mehr blicken lassen …

Pensaba que ya no volverías a aparecer.
Et moi qui pensais
qu’il s’en était débarrassé…

Justo quando eu achava que
você tinha sumido de vez...
Только обрадовалась,
что больше вас не видно…
อุตส่าห์คิดว่าจะไม่มาให้เห็นแล้วซะอีก...
