Enterprise's Graduation Trip

A white-haired girl races across the deep blue sea.

A brilliant smile spreads across her face.

She mutters to herself.

"I'm not going to make it back in time for dinner! I'm not going to make it back in time for dinner! Aaaah!"

"One day, a girl woke from a dream and became a bewildered shipgirl."

The protagonist is not based on any existing character, so you can think of her as an original heroine.
