The Demon of The Abyss

The Demon of The Ether is the female leader of the Maths Mafia and is by far their most notorious member. She rose from the abyss to seek refuge within Human society and therefore had to seek a disguise, as to not raise suspicion.

Everything was going to plan, until the machine that was transforming the demon suffered a fatal malfunction. this malfunction caused her disguise to be female, but with many male attributes combined. The male attributes that were combined include: superhuman strength, manly voice etc.

This disguise however, only covered the outer layer. The demon was still lurking deep within her. this demon has a extreme love of maths and thinks that anyone who doesnt achieve an A* must be purged from the Human civilization and she has many ways of doing this depending on the severity of the grade acquired.
 * An A grade will result in a gunshot wound to any part of the body except the head.
 * A B grade will result in multiple gunshot wounds to maim, not kill
 * A C grade will result in the trap door opening beneath you, causing you to fall into the jaws of the kraken
 * A D grade will result in decapitation via metal boomerang
 * An E and below will result in your soul being forever absorbed by the demon within. there is no proof that this is the demise that the victims face, as people are too terrified to admit to this happening as they fear they will face the same fate.
