What does "Tokoyo no Naganaki dori" means? I looked for it on internet but couldn't find the meaning of that so I wonder if "Eternity crying bird" is the meaning (it makes sense, Dori is bird and Naga is tear right?)
They explain it on page 77, it is the bird that wakes up Amaterasu when she hid away in a cave.
Essentially, this is post World War II and Sakawa and Nagato are about to be used as atomic bomb testing targets. Her comrades, the group of aircraft carriers in the middle of the comic, have all been sunk.
I think it's worth mentioning she could also be talking withing the confines of the game itself, and that there was an Akagi before her who was sunk and the poor/doofus admiral had to find another Akagi, because Akagi and Kaga are technically not sister ships.
Would they really be sisters though? I mean... They'd technically be the same person?
