Armageddon Evil

“[Armageddon – Evil].”
Darkness gathered around Suzuki Satoru and formed a swirling vortex.
Then, a gurgling sound came from bubble-like objects around him, and
demons were born from the abyss.
The first to appear were demons below level 10; there were a total of 128 of
those Inferior Demons.
There was no other word he could use to describe them other than
“deformed.” Their heads were swollen, their left arms were unnaturally thin,
their massive right arms were made of several tentacles twined together, and
their legs were of different lengths. They did not possess anything to tell their
gender apart, and yellow pus oozed from countless small holes all over their
bodies.
Their forms seemed to imply that they had been born solely to pollute the
world.
These demons, made for destruction and slaughter, were not under Suzuki
Satoru’s control. Instead, they attacked everything around them. Given the
circumstances, the only one near them was Cure Elim, and so they attacked it.

The bubble-like objects around Suzuki Satoru formed into a vortex again, and
now demons of around level 20 appeared — [Hell Scythes].
These demons looked like a fusion between praying mantises, humans, and
other creatures. Their gigantic scythes shone with a steely glint, and they were
coated in poison.
There were 64 of these demons in all.
Much like the Inferior Demons from before, they spread their praying mantislike
wings and flew towards Cure Elim.

At the same time, black bubbles appeared around him, and from them
emerged demons of around level 30 or so, Rotting Demons. They were over two
meters tall, with tarry black skin that resembled bubbling swamps. The bubbles
rose to the surface and burst, releasing a yellow mist. Despite being surrounded
by these demons who were wreathed in rot-inducing gas, Suzuki Satoru was not
affected, because he was undead.
There were 32 of them in all.

[...]

The black bubbles appeared again, and the demons which appeared this time
were around level 40, Supplicants. They had female bodies with long hair and
bluish-white skin, and that alone would not make one think that they were
demons. However, their eyes, noses and mouths were all sewn up with thread,
and their hands were also sewn together as though begging the gods for mercy.
There were eight of them.

[...]

More black bubbles spewed forth, and the demons which appeared were
around level 50 — War Devils. They were demons who wore full plate armor and
looked like warriors. They held bastard swords wreathed in black hellfire, and
their black wings protruded through their armor. They actually looked pretty
cool, and there were four of them.
Normally, the spell would summon two level 60ish demons and one more
level demon of around level 70, but Suzuki Satoru cancelled that and instead
chose to summon more lower-level demons instead. And so, there were twice as
many level demons ranging from level 10 to 30.
