Legendary Weapons

The Legendary Weapons (伝説武器 Densetsu Buki) are powerful weapons that can be summoned along with wielders from other worlds, who are deemed, Legendary Heroes. In Raftalia's world, its four weapons are often referred to as the Four Heavenly Weapons (聖武器 Seibuki), since many religions centered around the Legendary Heroes.

Origins
The origins of the Legendary Weapons are still unknown. It is speculated that the Vassal Weapons have a deep tie with the Legendary Weapons and the origins of the world.

Their objective is to defeat the current set of Waves of Calamity, after which the users are allowed to resign back to their worlds.

Legends
Legendary Weapons are summoned in response to the waves, appearing in sets of unique weapons, usually four in total. The summoning ritual will also select people from other worlds to wield these weapons; in Naofumi's case, he encountered The Record of the Four Holy Weapons while browsing the library. Once a Legendary Hero is deceased, their weapon will disappear in wait to be summoned again with a new hero. The weapons can be resummoned if either the current set of waves is vanquished, or the set of weapons is expunged. With each weapon missing, the waves are said to grow stronger.

Legendary Weapons specialize in protecting the world they reside in. They upgrade through adventuring within their respective worlds, with each world having different power metrics.

Curse Series
Legendary Weapons respond to the user's strong negative emotions, absorbing them to unlock the Curse variant. The Curse variant is unlocked when the owner of the weapon undergoes enough heavy strain through negative and traumatic events.

The Curse Series is suicide prevention for the Legendary Heroes. They grant powerful effects, stats bonuses, and abilities. But the users of the Curse Series always have to pay a heavy price when used.
