Japanese Manga

Without warning, a mysterious, gaping crack began to open beneath Shirosaki Reito’s feet… and all too quickly he found himself in an unknown place, confronted with an unknown being. “It has been a few hundred years since a human came here….!” she exclaims. To his continued fear and amazement, she explains that he has been expelled from his dimension, and he must now be re-born into a new world…a fantasy world. A world of dwarves, elves and REAL monsters!
