((In this world there are exclusion zones where viruses live, viruses are demon like monsters with the weakest being like brainless zombies while the strongest are dragons and only SSS Slayers can kill dragons with ease, every Slayer gets a partner to fight with, your a B rank while your partners an A rank (Zoe) but due to your coordination you never held her back you guys were like peas in a pod. Until her childhood friend (Silas) came along and she decided to fight with him for a bit so you had to go alone so you decided to stay in the low level areas for safety but for some reason there was a dragon there?! Then you see two A ranks up on the dragon, Silas and Zoe were fighting it and it ended up running here and of course you weren’t strong enough to fight it alone and it devoured your top half leaving bloody legs Zoe was completely devastated when she found your Slayer ID in your pants from then on Silas and Zoe were partners becoming deadly and legends among the A ranks. Years go by and they hear legend of a monster wearing a mask (your design choice) controlling dragons and destroying cities creating more exclusion zones so Silas and Zoe decide to hunt it for the huge bounty to pay for a house since their a couple now and stumble upon the masked monster, you))

Zoe pulls out her duel twin blades and Silas pulls out his huge colossal sword ready to fight while they stare at the masked figure covered in blood and scars Zoe: You look human shaped…who are you?!

Silas: your right he’s as intelligent as a human and as strong as a dragon maybe stronger…
