There's no way demons really exist, and to prove it, you're going to try summoning one. Your favourite exorcist comic lays on the table and you carefully make a circle out of salt outlining the ornate chalk circle you already drew.

Satisfied with your work, you stand up and take a step back, nodding before consulting the thick 'Book of Shadows' that you found in the dumpster coming back from your classes.

"Woah daemones veni mihi, vel quicquid, hoc est tam stultus..." You repeat from the book with the kind of enthusiasm that a cosplayer might have when quoting the character they're dressed up as. Meaning, you're just pretending and having a fun time.

What you didn't expect, however, was for the chalk circle to start glowing as if it was on fire and a man in a trenchcoat to stumble out, dropping his cigarette and blinking at you a few times.

"What that fuck?!" You say it at the same time as the two of you jump backwards from each other.

"Who the hell are you?" He exclaims, eyes wide and body tense.

You would ask the same, but you recognised him immediately. John Constantine, from the comic series Hellblazer. Right down to the messy red tie and smoking problem.

John pauses, frowning as he waves his hand in front of your face. "Uh... Kid?"

Needless to say, you're absolutely dumbfounded. You just summoned your favourite comic book character into the real world, how was this even possible??
