The empire Clesdia.

Currently, through the whole empire, a large scale investigation going on due news of the sudden rise of demons on the outskirt of territory caused by an unknown demon worshiping cult.

-Pov of Saiga Kuromori-

"Just like Saiga said, there is a real hidden passage."

"So that means the main force tricked by a decoy."

"Yes, and even if he receives, the message it will be too late to arrive."

"There is not enough time."

"It is okay we can stop, the ritual before they complete it."

I held their hand and assured them.

I definitely protect Anna's home town.

At first, when guild asked our assistance, I refused it because I didn't want to work under those disgusting nobles but, finding her home town on the list, I couldn't help but agree. I don't want to see her sad.

She was the first person who helped when I first arrived in this word four years ago.

As I entered the underground passage, I closed my eyes and scanned surroundings using my skill [Life Detection] and [Scan]. At the end of the tunnel, behind the gate, I found thirty people and eight or ten demons.

Among thirty people, I recognized a few faces of nobles from known families along with two elven children. As expected, it is nobles again fucking human waste that doesn't even deserve to breathe the same air with us.

Despite passage filled with traps and doors enchanted with all kinds of magic and runes, it was like a child play for me to erase all of them. Thanks for my cheat skill.

[Magic Mastery] was cheat I got when I transported into this world. This skill was as follows: First, I can use any kind of magic without any requirement; All element affinity; mana manipulation; and most of all, the ability to learn, create magic spells.

If I can be creative, I can create almost all types of spells that nobody knows, even what does it do.

"Let's stop that ritual."

While at using the chance, I better kill those nobles as well.

With Anna, Rose, and Lyra, I attacked their hideout while they busy preparing a ritual.

Just as I saw inside the hideout, there is a gigantic summoning circle that could cleanly fit onto the grounds of a small mansion surrounded by twenty people in black robe guarded by ten demons and nobles armed with their fancy weapons. At the center of the summoning circle, I saw two elven children in a cage.

Lyra and I charged at guards while Anna and Rose attacked cultists that controlling the summoning circle.

"Shit, how did they found this place!"

"Protect the summoning circle! if they stop this ritual, there will be no eternal life or unlimited strength for you!"

"F*ck! kill them!"

[Shotgun!]

Immediately I cast my custom spell towards guards. A faint blue ball appears on my palm and then explodes into tiny particles shooting towards guards.

Within just a moment, those nobles turned into mincemeat after being hit by million particles.

"As expected, those humans no use."

Said demons charged towards us six towards me and Lyra, four towards Anna and Rose.

[Divine Possession: Nemean Lion!]

A red flame enveloped Lyra's whole body granting her strength of mythological beast and transforming her into something similar to the race of beastman. With this, she easily cleaves through two demons in one swing of her blade.

[Demon bane!]

Demons in some way are similar to spirits, beings that inhabit the spiritual world using mana to manifest in the real world. Basically, what I am doing is, manipulating mana in their body and dispersing it, making them unable to hold into their form in the real world.

"You!"

Because of the large difference between mine and their mana other eight demons disappears into many pieces without even able to their sentence.

"No!, we must summon the great demon!"

Seeing their guards taken out in a matter of seconds, their leader screamed.

"For lord Crociel!"

Following his scream, other cult members took out a knife from their robes and began to pierce their hearts, spraying blood to summoning the circle.

"Quick, stop them!"

Fucking crazy people. Four of us tried to stop them all of able to sacrifice themselves into a summoning circle. While I pierced hearth of a cult leader, summoning circle began to shine in creepy red light, from the circle a large door appeared behind the two elven children.

The door decorated with a countless skeleton from all kinds of races.

With a creaking sound, the gate slowly opens up displaying pitch-black space behind it.

A greater demon slowly appeared from the gate. He had a strange large body, two long goat-like horn, gray eyes that full of anger and yellowmouth with long spear-like fangs twisted outward.

What should I do?

Should I take the children and run away with others or try to beat a greater demon?

"Who call-HUCK!?"

But we saw something even more unbelievable thing as something looks like a white slender hand pierced greater demon's chest from behind. But most surprised one was greater demon himself.

"W-what ?"

With a confused expression, the greater demon moved his head, looked his back. Then, the color disappeared from his face.

Literally color disappeared from his expression like in an old cartoon.

"No!"

"Please, don't. I want to live."

As if he saw something thing came straight from his nightmare, the greater demon began to struggle to leave the gate but couldn't do anything against this slender hand. Then he noticed us and asked something that I never thought, I hear it from the demon.

"Hey, hey you human!"

"Quick! destroy this circle. Erase those three symbols and this gate will collapse hurry!"

But at that moment our brain shut down from too much surprise, so we just stood there like idiots.

"You fucking idiotsss~."

With his pitiful last word, the greater demon disappeared into the gate being pulled back by a white.

"Wow, this gate smaller than I thought."

Then a figure that even bigger than a previous greater demon walked out from the gate. Unlike the greater demon, this thing doesn't have face except for her bloody jaw that looks like mission it skin. It wearing pure white armor around her chest and legs. But other parts are completely missing its skin just like her jaw.

It was something looks even more dangerous than the demon king itself.

First time I regret not following the demon's word.
