There is a parallel world called Harus. Harus is composed of two kingdoms that entered into a fierce conflict over a single object. The Kingdom of Duaris, where a princess named Masumi resided, possessed a very powerful blue crystal, which the Kingdom of Muragi greatly desired. The crystal has the ability to teleport people anywhere, as long as they know the name of the place. It also brings a person back to life after death, specifically reincarnating them in their native kingdom. This happens because the crystal carries the person’s name. In this confrontation, Muragi emerged victorious, the princess died, and the crystal was stolen. But something went terribly wrong! Masumi was reborn on planet Earth. How is this possible?!
