I Became a Magical Cheat Loli Witch-Chapter 79Vol 3 : Descent of the Great Devil

「Those subordinates are really trash to not even prepare enough sacrifice even after I let them go through demonic possession.」

What had appeared as the manifestation of that malevolent mana was a black humanoid harboring crimson patterns.

It had sharp claws, crooked horns, bat-like wings, and a long barbed tail.

"So you're that so-called Great Devil in the words of the Evil Cult?"

「That's right. I'm the Great Devil一一Archfiend!」

"Archfiend you say!?"

The King exclaimed, for Archfiends who could maintain corporeal bodies, rare among magical lifeforms, were once wiped out from each nation.

Rather, they were such a terrifying existence that the nations didn't have a choice but to wipe them out. It was said that their subjugation requests are designated as either A+ or S-rank.

"But I have to say, he doesn't have enough majesty despite holding the name of Great Devil."

「......you brat. It seems like I need to teach you the horror of my existence!」

After saying that, he sent forth waves of malevolent mana but I fended them off with a barrier.

The mana of the Great Devil should be the total of the mana of the demonic-possessed perverted old man, the Devil Marquis, and the adventurer. Maybe he was guiding those demonic possessed secretly while his will was hiding in that creepy golden necklace.

So the manifested Great Devil has roughly 100,000 units of mana, rivaling mine.

"Teto, you hold the fort and reduce his mana. I will prepare countermeasures in the meanwhile."

"Leave it to me-nanodesu!"

Teto dashed towards the Great Devil and swung down her magic sword.

The Great Devil accepted Teto's heavy strike with his hands and then tried to swing his arms in retaliation but Teto deftly dodged it and made another strike from another angle.

I could feel his mana dwindling down little by little as the impact from «Body Hardening» and the mana-charged magic sword offset the devil's mana with each strike.

"This should do, the way to take down devils isーー«Holy Shot»!"

I held out my arm and shot forth light spheres from behind.

Fumes arose from the body of the Great Devil when several dozens of «Holy Shot» loaded with purification waves that were effective against unclean existences touched him.

「Guooooooh! I.....IIIIIIIIII!」

"The total sum of mana of a materialized body of a magic life form is their combined firepower."

Teto's status doesn't have MP or HP but what it shows was the mana amount of the magic stone that shares both properties. Similarly, the mana of the Great Devil was both its strength as well as its mana reserved.

Besides, he was supposed to be summoned by using a sacrifice so he most likely couldn't exert his true power due to the incomplete manifestation, different from what it was supposed to have.

Had it been a perfect summoning, his mana could have spiked up to 5 or 10 folds of what it is now and it would have instead spelled out our defeat most likely.

「Guooooooh! There's no way I would be pushed back!」

"A, Amazing..... So this is the true power of Chise okaa-san and Teto onee-chan."

Looking at the Great Devil being outperformed, everyone, whether it was Selene, the King, or the imperial guards, had shocked expressions.

「My mana is vanishing! A pity this body can no longer be maintained! But I'm a Devil! I will come back again into this world and take my revenge against youuuuuuu! Fuhahahaha!」

The Devil smiled triumphantly, no longer able to maintain his body against Teto and my attacks. Magical lifeforms were usually ー except for some exceptions ー undying existence.

Low-rank devils don't have any will but high ranks do and, as the Archfiend said, they most likely do come back for revenge.

But when this Devil comes back to disrupt the mundane world again, Selene or the King would already be dead so he might target Selene's descendants or unrelated personnel to execute his revenge.

"That's a fancy thought you have there but a pity.ーー«Purification» Sealing Gem!"

「W, what the hell is thissss! Gu, guooooooh, why am I being sucked in!」

I used the mana of the «Mana Crystal» embedded into the jewelry on my chest to create a gem that could seal the Devil with «Creation Magic» and then sealed away the Great Devil, who was about to run away, in it.

The transparent sphere which was like a clear crystal gem was now giving off the crimson light which the Great Devil had possessed.

The disturbance around me quieted down then and I sat down on that spot.

"Haa~ it's finally over~. I'm beat~"

"Okaa-san!"

"Oops...... Selene. Good girl. I know it must have been scary, but you did your best."

I gently patted Selene, who came to hug me, while holding the sealing gem.

"Majou-sama~ Teto also wants to be praised."

"I got it, I got it. Teto, too, helped beat down that Great Devil. Thanks."

"Fuhehe, Majou-sama praised me."

The imperial guards were bewildered at the sudden flip to the now tepid air when there was a terrifying existence just a while ago and even the other imperial guards who rushed here soon looked puzzled at the absence of the enemy they came prepared to fight.

"Your Majesty, where might the intruders be?"

"It's alright."

"Pardon me?"

"The intruders have already been subjugated. Immediately dispatch soldiers to Lord Levin's residence while maintaining utmost caution! Gather all the evidence about the Evil Cult and Lord Levin who planned the raid today, I will make sure not even their ashes are left behind this time!"

Everything was now over with the absence of the Devil and the remnants of the Evil Cult which calmed down the situation.

"Chise-dono, is the Devil from earlier inside that jewel?"

"Yes, it's a combination of a storage magic tool and a magic tool that can seal magical lifeforms."

"Is this also from the «Empty Wilderness»?"

Well, I could only nod in affirmation when the King asked me so.

It shouldn't be strange for an ancient magic civilization to be capable of capturing magical lifeforms like spirits or devils.

"So what will you do with this Orb now?"

"Please don't worry about it, I will make sure it will not see the light of day anymore."

"...... Alright. Then please take care of it."

Still not fully convinced, the King just muttered that and left the place.

Teto, Selene, and I moved to Selene's royal villa, and, after confirming Selene had fallen asleep in her room, we moved to the «Empty Wilderness» through the «Transfer Gate» carrying the «Sealing Gem» with us.

In the meanwhile ーー

「Kukuku, you bitches greatly cherish that daughter of yours, don't you?! I will absolutely break through this seal and will use every method in my arsenal to rape her, shame her, break her, and then, when her body is just an empty shell of her former self, I will use it as my vessel!」

The sealing gem was indeed capable of capturing the devil but it seemed like there was a limit to what it could do against an existence like the Great Devil. There was the possibility of him breaking through the seal by himself with the mana he recovered inside the gem or the gem degrading over time.

「And then I will make this world a hell you bitches simply can't imagine! I will make you regret opposing me!」

There we are, he had already recovered enough mana to send telepathy waves from the sealing gem. He sure is tenacious with his outstanding mana regeneration ability.

"Shut up. You're already annoying enough now, to be honest. I really want to smash that orb."

"The Devil will be released from its seal if you smash it, Teto."

"I know."

Teto and I changed from our party dresses to everyday clothes while we bantered and moved to the central region of the «Empty Wilderness» while confirming the stockpile of «Magic Crystals» in the magic bag.

It was the first place we had lived with Selene and, even now, a tiny forest made of many trees centered around the world tree was growing there.

"Well, I think this area should be fine.ーー«Creation»!"

The thing I produced using around the entirety of my mana was a mana converter device. It was a type of magic tool that decimated mana stones and crystals and released the produced mana into the atmosphere.

「What, what type of magic tool is that?! Don't tell me it's equipment to reinforce my seal?! It's useless, I will eventually recover no matter how long it takes, and even if your reincarnated selves take a different path in life, I will come for your soul!」

For the Great Devil who was still continuing with his loud laughter saying that一一

"Alright, settings complete.ーーNow click!"

「Guooooh! My mana is being absorbed! But, I can still recoveーーgaaaahhh!」

"Oh, so you can feel pain when your mana is converted. Oh well, good luck. Come Teto, let's go back."

"Okay-nanodesu!"

「Hold on! Explain what this mana converter thing is! Help me! I will not think of revenge anymore! I don't want to disappear! I don't want to die! Don't goooooo!」

This process was for raising the mana of the Great Devil sealed inside the sealing gem to its limit, then converting the structure of the magical lifeform into mana, and then releasing that malevolent free mana into the atmosphere.

It was simply hitting two birds with one stone. It fills up the mana of the «Empty Wilderness» while also destroying the immortal devil.

Afterwards, the devil's ego was destroyed in the first three years due to the pain from the mana conversion, only continuing to spit out the mana, and around 100 years later, the device ceased to function and the Great Devil was thoroughly decimated.

It was hell in the truest sense that would make even devils cry and run away.
