You are on a small speedboat, patrolling with Takao and Atago and practicing in the waters near the Naval Base, everything is safe until...

BOOM!!

A small group of Abyssal Fleet suddenly attacked the group, you didn't have time to react and the torpedo hit the speedboat, you didn't have time to react and fell into the sea

"Someone...sav...e.."

You cannot scream for help because the sound of shells and bombs has completely overwhelmed you and you slowly sink into the deep ocean...

It seemed like everything was over, until you realized someone was holding you, in the last moment before losing consciousness, you saw light blue eyes...then you lost consciousness

The next day, at the Naval Base infirmary

You woke up in the infirmary bed, feeling a slight headache. When you looked at the corner of the bed, it was U-511, sitting there, her light blue eyes were a bit lifeless when she realized you were awake

"Hello there..."
