demon installs lots of magic, lets him hurt magic god

“Thus, I can become the manager seated in the unmarked eleventh sphere!! My name is
Qliphah Puzzle 545, my number is the true eleven, and its meaning is ‘the stepping stone
of wickedness that supports good deeds’! The path of seventy-eight cards is found here. I
provide power to my contractual master, the transcendent lifeform who controls the
entirety of the still nameless third three. I offer the path of survival to that being! I offer
him the wisdom found beyond the Abyss!!!!!”
Aleister Crowley had once failed at this.
The experiment had been to take Great Demon Coronzon inside his body in order to cross
the Abyss that no normal human could cross, but Coronzon had refused to cooperate and
the experiment had been halted.
But what if?
What would have happened then if the demon had truly offered to help and had joined
him with no ill will or deception?
The answer was revealed here.
“Magic God, you still cling to the surface!! So don’t think you stand a chance against my
master who has crossed the Abyss!!!!!”
An explosive noise burst out.
But it was not the sound of the violent gale Accelerator had been trying to unleash.
This was less distinct.
It was an invisible power that covered every part of the world.
His vector control ability twisted it into a vortex that rushed toward Nephthys like a giant
spear.
“Tch!!”
The brown goddess had preserved her beauty even as her torso was blown away, but she
finally clicked her tongue and pushed Accelerator off of her. This slightly diverted the
spear’s trajectory so it only sliced off a tuft of her long silver hair.
Something was different from before.
The separated hair did not reconnect and it simply rotted away.
She rolled away from him.
Once Academy City’s #1 monster got up, the translucent demon wrapped her arms around
his neck.
She would not run away any more.
She was no longer afraid.
She now understood what her contractual master had said. Don’t cry. Don’t be afraid. Yes,
she could really and truly rely on him, so she did not even need to fear the possibility of
her actions harming him!!
“You don’t understand magic and you don’t know the rules, so that Magic God could mock
you and act all omniscient and omnipotent, but that ends now.”
In order to truly give him her power and to fight while harming each other, Qliphah Puzzle
545 glared directly at Magic God Nephthys.
“I will provide you with what you need to know by installing the knowledge of the entire
tree of seventy-eight cards. It doesn’t matter if you are aware of it or not, master. Just
control the vectors however feels right to you. All of ‘us’ will make sure it all works out!!”
