Infini-T Force

Seventeen-year-old Emi Kaido hasn't seen her father in ten years. She lives alone and feels increasingly disaffected, challenging the world to kill her and feeling empty when her daredevil behavior doesn't "pay off". All of that is about to change when she meets four heroes from alternate earths. When their worlds were eliminated by an evil man known only as “Z”, they instead came to Emi's, and together they determine to stop the destruction.
