After the last destruction of the world, the time and space cracks left behind gave Rakshasa and monsters the opportunity to reincarnate. The smoky atmosphere that tormented the good earth. The gods who originally wanted to reincarnate into the earth were killed by the reincarnation of these monsters. The earth seemed hopeless.
One of the gods wanted to save his daughter on Earth out of selfishness, but he did not expect that the experiment would fail, so he summoned the soul of an unrelated Earthling. Faced with this situation, the idea of destroying the body and eradicating traces was replaced by this person's potentially useful plan. Therefore, the heroine was fortunate enough to see other planets outside the Earth, various types of life forms, as well as various tools and weapons combined with technology, spells, and magic.
