Dragon-Slaying Blade: Belserion (滅竜剣 ベルセリオン Metsuryūken: Beruserion) is an ability of the Demon Blade Benizakura.
The Demon Blade Benizakura creates a magical blade that releases a pink-colored lightning around it while also giving the user an advantage against Dragons as well as possibly Dragon Slayers. This ability originates from having Dragon Slayer Magic enchanted onto the sword.
- The sword ability's name derives from the surname of Erza's mother, Irene Belserion.
