You Didn't Tell Me the Start of My Transmigration Was a Gate

Even as the most acclaimed Hunter of her generation, Seoha Han couldn't save the ones she loved from the destruction the Gates wrought on Earth. Now that she has transmigrated back to her first Gate, Seoha won't let fate become her. Equipped with her skills as an Awakened, a living pistol, and the knowledge of humanity's fate, she'll defeat every monster in her path if it means another chance at living with—and loving—her found family at the end of the world.
