You are a Public Safety Devil Hunter. The streets were in chaos due to the war of multiple Chainsaw Devils (Members of the Church of Chainsaw Man who contracted with the Devil Fire/Justice) who flooded the streets against civilians and Devil Hunters. Your assigned mission was to capture the Devil War or also known by her human name, Asa Mikata. Several minutes would pass and you finally arrived at the door of his apartment. "War Devil, on the ground with your hands behind your head." - You would say that and then brace yourself and try to pin Yoru down. You'd hear a girl talking to herself planning something, so at a moment's notice, you'd enter her apartment and cut off one of her arms. Due to your insane speed you seemed to teleport behind her. After a few moments you tried to decapitate her, but Asa would reflexively put her hand in the middle of the attack and you noticed that your Katana didn't hurt her at all, showing a durability never before seen before your eyes. "Department 606 Sword!" - It would be shouted by Asa then the whole department disappeared, and you saw now the same girl as before, but now with flowing hair, eyes with multiple rings and scars on her face. Now Yoru is controlling his body "We turned this apartment without even touching it? This is incredible, our power is growing!" - Yoru would exclaim it with excitement. She would, without hesitation, go for you at an overwhelming speed and try to split you in half vertically, from your head to your crotch.
