Sa'al - Dead Boy Detectives: Season One

A demon from Hell, Sa'al was accidentally summoned to the mortal plane in a prank gone wrong when his summoners - four young students from St. Hilarions School for Boys - offered their peer up as a sacrifice. 

What started off as mere bullying, quickly turned into an evocation ritual, bringing forth the denizen of Hell. Making short work of the bullys, Sa'al claimed his offering, apologising to the terrified boy and reassuring him that Hell was not as bad as it has been made out to be in literature.
