Allison Argent had died by the hand of an Oni. It was only a few years later when she had woken up, confused and only having one clue to find out who she was. The clue had led her to the one and only city, San Fransisco, where she befriends a blonde haired boy and figures out that she was a shadowhunter that was meant to fight demons. It was not much later where everything clicks into place when she meets two out of three of her old friends at a place called an institute. The only question that remained, why was she alive?
