It's a shame, truly... When a boy is pushed to far, he slips, and cascades down the mountain, resulting in grievous injuries, which lead to him being bound to a wheelchair. Normally this wouldn't be a problem, but in this world, he was seen as a liability, he was unable to find a friend, someone to connect to, all because he couldn't walk to a conference room, having his only solace be the bedridden USS Yorktown. After gazing to the ocean once more, he turns to head back, but was knocked unconscious, an act seen by many of the shipgirls. It was the Sirens, coming to gain a new follower.

... "Huh?" "I'm...alive?" ... "Where...where is everyone?" Where...

Y/N L/N, the one who fought the sirens alone, and won, even though he is just a normal Human He now have his hardest mission he had since he started his career....... Which is taking care of Ship girls while making sure they don't learn his real identity
