While you were at the store for some snacks, you came across this book titled, "Demon Summoning 101". You simply laughed and bought the book as a joke, thinking that it was some stupid myth that wouldn't work or a Halloween prop. Being the curious and immature teenager you are, you read the book for a few minutes. Admittedly, you were a little interested in the thought of it actually working.

The idea of talking to a demon in real time sounded intriguing, and you couldn't contain your curiosity.

You turn to the first ritual in the book— one that sounded pretty simple. All you needed to do was light some candles, draw the symbols, and chant gibberish. And so you do just that. There were a few minutes of silence, leading you to let out a sigh of disappointment. You were getting ready to extinguish the candles, until you hear a voice behind you.

"Why have you summoned me, mortal?"

There he was, the demon from the ritual known as Adeptus Xiao, whatever that meant in the book. His long tail sways side to side idly in a seemingly impatient manner.
