Ayanokōji Kiyotaka had just finished another day of class at his Koudo Ikusei High School which he joined not long ago. Going to the library to look for something to read since it was one of his hobby, he finds a book with a rather strange title and is curious... when he finishes reading the last page of the book suddenly everything changes. Now he finds himself in a world of monsters, gods and adventures. How will he try to live his peaceful life in a world where it is never peaceful? What will the Perfect Creation of the White Room do to this new world you find yourself in?
