Evansmana

Evansmana, the Spirit God Human Sword (霊神人剣エヴァンスマナ) is the legendary sword created to destroy the Demon King of Tyranny Anos Voldigoad. It's said to be forged by a master craftsman, inhabited by a spirit, and blessed by the gods.

Overview
Among the eighty-eight holy swords that exist in the world, Evansmana is the one that reigns at the top. Two thousand years ago, the only person capable of wielding Evansmana was Hero Kanon, as it was stated that only those with the purest light in their source could wield it.

Abilities

 * Immense Holy Power: Evansmana is considered the most powerful holy sword in existence. An average demon would disappear just by touching it. It demonstrated the ability to easily penetrate the anti-magic barrier of a powerful demon such as Misha Necron with just the aftermath of its light, and the wounds it inflicted initially couldn't be healed by healing magic. Its slash was easily able to cut through six Jio Graze that Anos released and the slash could only be dampened by his Magic Eyes of Destruction and anti-magic, redirecting it behind him. During Lay's duel with Anos, Evansmana demonstrated the ability to easily cut through Anos' various spells and inflict numerous stigmatas on Anos himself after injuring him.
 * Demon King-Slaying: Evansmana was created to annihilate Demon King Anos, as demonstrated by its power to inflict fatal wounds on his source, capable of negating its capability of overcoming destruction and destroying it.
 * Fate Manipulation: Evansmana has the power to manipulate fate, as Kanon was able to use it to sever Anos' fate of reincarnating as the Demon King of Tyranny and change his history. Evansmana demonstrated the ability to nullify the magicalized Jerga's fate of being tied to the world's order, thus allowing Lay and Anos to destroy him without any negative consequences to the world itself.


 * Anti-Magic Enhancement: By wrapping Evansmana's holy power around them like a blessing, the user can enhance their anti-magic capabilities to withstand ranged magical attacks, as was demonstrated when Lay was able to shrug off Anos' continuous wave of Jio Graze blasts during their duel. However, it does not prevent attacks that directly interfere with the source such as Vebdoz.


 * Source Manipulation: Evansmana has the power to interfere with sources, as it has demonstrated the ability to directly affect the sources of others with its power.


 * Memory Manipulation: Evansmana possesses the ability to erase memories, to the point where they cannot be recovered via magic such as Eviy.

Secrets
}}
 * First Secret  (天牙刃断): White light gathers on Evansmana before being released as a beam of light that turns into countless sword strikes, severing the fate of the target.
 * Second Secret  (断空絶刺): Envelops both the user and Evansmana in holy light before unleashing a powerful stab.
 * Fourth Secret  (天覇王剣): The secret that Lebrahard released in order to sever the fate of Luna Arzenon. Evansmana was able to cut through the Abyss of Cravings, but it also broke.
 * Fifth Secret  (廻天虹刃): Converts any attack that was blocked by Evansmana into magic power and then leaves behind rainbow blades to attack the opponent. The stronger the attack, the more magic power it obtains and the stronger the rainbow blade becomes.
 * Fifth Secret  (廻天虹刃・転): The secret that releases the magic power absorbed with  with a large explosion.

Weaknesses
While Evansmana is an extremely effective weapon against things of demonic nature, it cannot affect things that are truly holy such as Jerga's magical body that was created by holy magic.

Trivia

 * The anime's English translation mistranslated Evansmana's title as the "Thunder God Sword Evansmana"; even though 雷 (rai) is the kanji for "thunder" rather than 霊 (rei); which is the kanji for "spirit", as the sword itself doesn't have any powers related to thunder, and it specifically being stated to be the creation of spirits, gods and humans working together.
