Hmm, If we were to demonstrate with these...Let's say that this sugar cube is "Right now", the milk "The Great War era" and the spoon as the length of time between the two period of times.I don't have the habit of counting the days or years that passed by... So I don't know about such a thing.But didn't the 2nd generation first appear approximately 30 years ago? You don't look like you're that old at all.I am one of the "2nd generation ship-girls" that were made during the last stage of the war.After the conclusion of the Great War half a century ago... Abyssal ships began to show up. It was known as "The First War against the Abyssal". Or more commonly refer as The Ship-girls construction era...
