Dragon Slayer Sword: 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 black lighting around it while also giving the user an advantage against Dragons or Dragon Slayers. This ability originates from having magic enchantment onto the sword.
- The sword ability's name derives from the surname of Erza's mother, Irene Belserion.
