Admiral Life from Zero

A young admiral tragically loses his life during a deep-sea fleet raid. When he wakes, he is horrified to find himself back in the port area where he died. And so, to protect the ship girls who have entrusted their lives to him, and to honor the vow he once made, the young admiral turns back time again and again, changing fate... No matter how many times I face death and despair, I will create a happy ending where everyone survives!
