Time Traveler

"The young Mizuno Mai is the result of a relationship between a spirit and a human being.
From the beginning of her life, she has been trapped in some misterious and curious worlds defended by some living beings called "Guardians." Her birth broke god's rules and her grandfather will be chasing her to erase her exsistence and everything around her as part of a personal revenge. Because of that, and with a bit of help, she will be able to travel to the past, present and future, and grow in a lot of ways to face her fears."
