Longinus (聖者殺しの槍) is one of the Twenty World Items of YGGDRASIL.
During Ainz Ooal Gown's raid on the Great Underground Tomb of Nazarick, one of the guild members wanted to use Longinus against the Lord of Helheim.
This World Item is capable of complete deletion of the target, but the price to pay for its use was the complete deletion of the user. After having the data deleted by this World class item, unless another World Item was used for revival, there was no coming back.
- According to Christian lore, the Spear of Longinus was used to stab Jesus Christ and was drenched with his blood. This name was taken from the roman centurion, who thrust the spear into Christ's side at the crucifixion.
