Gadra's nihilistic hazard

‘Then, with the highest level of darkness magic he’s most skillful in, let’s show it in this place!’ Gadra thought so.
And――

「Oh thou who suffers in everlasting starvation, heed my call! “Nihilistic Hazard[4]”!!」

The strongest of Divine Magic is the ultimate anti-personnel destruction magic “Disintegration” which is well-known.
It’s known that there’re a few people who can use it, but its high power is guaranteed.
It’s said that person who receives a direct hit and can survive doesn’t exist[5]. However, if there’s weakness of this magic, it might be that it’s a single target magic.
The attack range is extremely short. It was a natural reason why the magic has a high power, but against an army it was a useless magic.
Because he’s well informed about this matter, it might be why Adalman used the strongest spell in summoning magic――
――And what Gadra chose was the opposite of “Disintegration”, the strongest large-scale annihilation spell of darkness magic.
A very large magic formation emerges on the ground and the sky.
And, like connecting the sky and the ground, dark electric discharge begun to appear――and innumerable spheres of electricity were released.
The fang of darkness that swallows all substances.
It’s darkness magic that brings void to this world and is considered as one of the forbidden spells.
The void let loose in the world doesn’t vanish until it’s negative energy turns null.
Everyone inside the barrier of the magic formation that links the ground and the sky is devoured and their existence is erased.
It was one of the ultimate magics that was feared, as a mistake in its control can bring destruction to the world.
