His name is Subaru Muryou, and with his arrival, everything begins to change. Students suddenly begin to display amazing psychic powers, a giant white guardian keeps appearing in the skies over the city to fight off gigantic alien creatures, and men with threatening weapons are haunting the shadows of the school grounds.
