It's been over ten years since Achlys is going around collecting some information about Demon. Her obsession with Demon comes from her saddest childhood memory. Growing up in a family that put and trust their lives in the hands of Gods, Achlys never thought that she would ever discover something about her parents during the last moment she had with them. At the night her parents died, their town is under attack because of some secret political war. Her parents were trying to get help from the Gods they worship until they desperately turned mad because they didn't get any help. Her mom, Kimiko, takes out something that turns out to be her family relic that contains a devil named Chordeva and casts some kind of spell. Her mom then gave that relic to Achlys right before Achlys’s parents turned into some kind of demonic creature and started attacking the soldier that attacked their town. This momentum gives Achlys a chance to run and hide with the relic she got from her mom.
