Asta

How Asta joined the Tourney
Asta is an orphan who was left under the care of a church during his infancy who has aspirations of becoming a Wizard king, possessing no magical power yet overcomes his weakness by training his physical strength. He is the wielder of the five-leaf clover grimoire and a member of the Black Bull squad. He uses an anti-magic sword that is capable of nullifying any form of magic called the Demon Slayer Sword, and an anti-magic sword that is capable of absorbing and using other magic called the Demon Dweller Sword. The Demon Dweller sword was found in a dungeon and was not made by his Grimore, but it became part of it later, after Asta used it. According to the Witch Queen, Asta's swords used to belong to the Elf Elder, a powerful mage who once nearly destroyed the world with the ancient demon that he conjured through forbidden magic. The anti-magic energy is constantly flowing through the swords, causing many people to be unable to wield them. However, since Asta was born without magic, he was unconsciously able to stop and start the flow of that power. After his arms were healed by the Witch Queen, the flow of power has gone faster, resulting in Asta able to become the vessel to the force of anti-magic itself.

Having been chosen to take part in the second Tourney, Asta finds his Anti Magic abilities put to the test against one Ophelia.
