The Watcher

When a friend group decides to perform a ritual to summon a demon all for good fun, know it wouldn't work, they end up releasing something much worse. They try their best to ignore what had happened and what they had released, but that only worked for so long.
The demon however, had never had an interest in them. And was far more interested in the younger brother of Kiki, the girl who suggested they perform the ritual. But this, made no since. Why? Because, Travis had no idea that his sister was even having a sleepover that day.
With this demon now attached to him, Travis tries everything to get him to leave, even going as far as to perform an at-home-exorcism. But all that does it is make the demon more invested than he had been to begin with.
Travis, however, is determined to rid himself of this demon. But when the demon offers something to Travis, his goals seem to readjust.
