Reborn After Villain Trapped My Sister, I Killed Madly

The third day of our Labor Day RV trip, Dad got out to fill up on water, and Mom and I went to the market to buy groceries. In my past life, a burly man in a face mask pried open the RV door and trapped my sleeping sister inside. Terrified, my sister video-called me, crying, begging me to save her. "Sis, help me! There's someone in the RV!" I ran back like a madwoman, and got there just in time to see that man climbing out of the RV.
