Chronicles of the Vanishing: A Pervert, a Prick, and the Perfect Ace

In a world where monsters, demons and ghouls lurk within the shadows, three unlikely allies find themselves entangled in a web of mystery and danger:
-A pervert
-A prick with the largest chip on his shoulder
-And the 'perfect' not-so-perfect Ace

One second, Aurelius was raiding a rogue cultivators cave, doing his part in ridding the world of evil and becoming the most powerful cultivator-the next, he finds himself stuck with a girl who has the impediment to stutter and a boy who is a bonafide pervert.
With inexplicable disappearing cases popping around town and classmates mysteriously vanishing without a trace, can these three somehow put their differences aside long enough to work together and solve the puzzle surrounding the missing students?

The energy here is "why is it, when something happens, it is always you three?"
