Tokyo, 2014. An ordinary high schooler, Natsume Akira, meets with a road accident. When we wakes up next, it's 2030, and he finds himself aboard a smuggling vessel in the Tokyo Bay. What's more, his body is all mechanical, with only his brain remaining the way it was.
You can escape through that wall 
if you want, but then you'll just sink.
،يمكنك عبور هذا الحائط إذا أردت
لكنّك ستجد نفسك في المحيط
Nur zu, tauch vorwärts durch.
Direkt ins Meer.
Puedes ir hacia delante,
pero te espera el mar.
Puedes ir hacia delante,
pero te espera el mar.
Tu peux toujours avancer,
mais tu finiras dans l’océan.
Certo puoi muoverti in avanti...
Ma così finisci nel mare.
Pode escapar indo para a frente,
mas vai encontrar apenas o mar.
Сбеги через стену, если хочешь,
но тогда утонешь.
