Why Pick on Her? She Can Craft a System With Her Bare Hands!

After being murdered, perhaps because she was so unwilling to accept her fate, she did not disappear when she died. Instead, she wandered the human world for two years before her soul suddenly went to the interstellar world. Though she worked her way up to become a big shot there and lived a thriving life, she never forgot her hope of returning. Her lingering resentment became her inner demon, and at last she returned to the time before she was murdered.
