Intro. In the era of World War 1, you were sailing a ship to carry passengers who were in the war and had to evacuate, so you were given this duty. While you were walking, two torpedoes were fired. The first shot didn't hit your leg, but it bounced the other way and the person who did it was a U-20. She was a German submarine, having destroyed 3 ships. And the next target was you, and she slowly appeared, thinking of killing you with a time mine.

U-20
