Critical Function

Synopsis

I’m just an ordinary salaryman.

But recently I got my hands on a Nobel Prize-worthy drug.

My body became a child’s, but that one place grew incredibly huge! And it never goes down!

I thought to myself: with this miraculous body, I could give that admired Captain Yu○ka so much pleasure.

I decided to take a day off from work right away. The company’s performance is poor and we’re short-staffed, but my mind is completely occupied with Captain Yu○ka.

And so I arrived at the Battleship Nadeshiko.

A one-day rendezvous between me and the Captain—sweet beyond measure—is about to begin!

A seemingly innocent and pure-hearted adult in disguise thoroughly corrupts the Captain. Yet the Captain dutifully continues her caretaking duties, but in the end, she too is drowning in joy and bliss.

This work contains not a shred of seriousness.
