An unknown fragment of another dimension invaded the Nasuverse, twisting history. Legends from beyond this world mingled with the Throne of Heroes.
It all began when Waver opened a package and found inside a fragment of King Arthur's scabbard...
The smiling Grim Reaper, the knight of the Holy Lance, the shrine maiden of the Warring States
Sword and spear wail in battle; only the victor is the strongest.
The sorcerer from another dimension, the summoner of fantasies, the murderer of urban legend, the vampire king of destruction
The ultimate in magecraft, a reality warped
Only the uncrowned king can lift the sinful Holy Grail.
