The Slayers From 2882

When a Demon attack brings down an entire school and leaves many injured and dead, 17 year old Ava Donovan can't seem to recall what happened and what lead up to it. She is aided by a commander, who has Ava under their wings and trains her to be a Demon Slayer. When the time came for Ava to cooperate and befriend people she was randomly assigned to work with, they end up coming across the Queen of Hell who places a curse on them. As a deal, she has them travel to different parts of the world, searching for Seven relics belonging to each of the Seven Deadly Sins. They're on a time crunch and must collect them all before time runs out.

[This is pretty much a sample of a story a friend and I are working on at the moment. We do plan on making a webcomic instead of writing. However, we thought it would be best to just get something out there and see how it does. So if you do end up getting invested, be sure to stay tuned and maybe commenting about the story thus far. We'd love to hear your insight about it as it'll help with improving our story.]
