Chapter Text
The fighting was intense, but after a long year of war against the demons that invaded the human kingdom, there was only devastation and death as far as the eye could see, the soil became cursed where nothing grew anymore, the animals died a lot due to the plagues that the demons brought, the only human still alive was Asta. Seeing the anti-magic wizard as the only one capable of stopping the demons from bringing their destruction to other continents, Salamander, Undine, Dryad and Sylph abdicated the universal law of mana and allied themselves with the gray one and began to reside in the clover grimoire. of five leaves. The four Elemental spirits were not the only ones to do this, after the death of Nacht Faust the demons Gimodero, Plumede, Slotos and Walgner entered a state of pure hatred and desire for revenge, they asked to sign a service contract with Asta, but having a kind heart, he opted for an equality contract, just as he did with Liebe. His grimoire now had 3 elven swords, Captain Yami's katana, the rosebush sword that Captain Charlotte Roselei gave him before she died entrusting the future to the little one (when it came into contact with anti-magic it became a rosebush sword demonic, capable of nullifying magic and imprisoning the opponent, its black roses bloom when absorbing the opponent's blood), 5 lower-ranking demons and 4 Elemental spirits.
The battle reached its final climax, Asta only had the strength for one last attack, the demon in front of him was the last demon alive (not counting the 5 with contracts with the anti-magic wizard), his name was Zarkron and he was fourth in the Qliphoth rankings. They were standing on the dead earth of a completely destroyed village, the two faced each other in total silence, ready to attack at any moment, the tension was so thick that you could cut it with a knife, Zarkron was the first to break the silence .
– I must thank you, kid. – He said in his squeaky voice. – Thanks to you spending the last 3 months killing my demon brothers I can have fun alone. – He spoke dreamily, already imagining the cries of despair of humans from other continents who had no mana and could not defend themselves. – All I need to do now is steal what little time you have left to live.
– Keep dreaming that I’m going to leave you alive. – Said the gray-haired man with his sword in hand. – Not even your time magic will stop me.
As soon as the sun set, disappearing behind the skull of the demon that almost destroyed humanity 500 years before, the two attacked each other. Zarkron created a scythe with time magic while Asta used the demonic union with Plumede to dodge while attacking with his katana, after a few exchanged blows Asta realized that he wouldn't achieve anything just by dodging so he switched to the demonic union with Slotos, who soon noticed the error when receiving blows that were not fully blocked. The fight ensued for hours with Asta constantly switching between his demonic unions, Asta was exhausted while Zarkron seemed to laugh at him.
In an act of desperation Asta tried something that could only be called “the worst idea in the history of thought”, Asta made a demonic union with the 5 demons and attacked the time demon, his suicidal plan would only last for a while. minute. Asta pierced Zarkron's chest with his anti-magic sword, after which his transformation was undone, that was when he felt the agonizing pain in his chest, when he looked down he was horrified by the scene.
– I may even die now, but I will take you with me, damn human. – Said the demon as he plunged the temporal sword deeper into the gray-haired man's chest.
The demon disappeared after dying, but his sword was still stuck in Asta, the sword that the anti-magic wizard used flew into the grimoire, which soon absorbed the exhausted demons into its pages and released a pulse of anti-magic. Asta was alone again, his vision was darkening, feeling death approaching he just gave in to the silence that remained after the death of the last demon and the last human on the continent. Darkness was all that was left, Asta felt nothing, heard nothing, but the silence was broken by a scream of fear that Asta recognized at the time.
