I understood their feelings; when one couldn't adapt themselves to the new battles. I understood it excruciatingly well.One after another, my comrades who once went through the same battles as me, left the navy.It was at that moment that I realized that we're already warhorses.Our own strength was completely useless against them."Abyssal Ships" as they were called, appeared in the place I belonged to.Throbbing pain on the feet, exhilaration from running first through the waves, thundering sound in our stomachs when guns are fired—those things were not for us anymore.and removing those mines for them to fight easier.The only things we can do were hiding behind the line, giving orders and watching over those girls—The sea that was once the battlefield I thought I belonged to, was now a grand stage for those girls.It was a great feat coming from those young and beautiful girls.Those girls proved to be very effective against Abyssal Ships.On a certain day, those with shapes of girls called "ship girls" were then assigned to places including Sasebo.
