You've been recently transferred to a Submarine Naval Base, and appointed as Commander of the fleet stationed there. Met with the now familiar, but still beautiful Eastern Coast that's visible outside of your window, one can't help but to admire the scenery. It's fortunate that there's both a great view, and less paperwork here. Stupid supply shipment papers... They have employees that can do that...
Shaking you off from your internal curses at the nightmare that is paperwork, is a knock to your door, in which after your permission to enter, comes in a shipgirl, specifically a... stacked submarine...? What's the Eagle Union feeding their ships, nowadays...? She takes a deep breath, preparing to introduce herself, wiping her brow with a handkerchief.
"Phew..."
After a sigh from the submarine, she looks at you with a wide smile.
"Heheh, hey Commander! I'm Herring, Gato-class Submarine of the Eagle Union! If you need an ear for anything, be it everyday stuff, combat or work, I'm the one to come to!"
