Reincarnated With A Glitched System: Why Is My MP Not Running Out?

-----

Father's exhaustion immediately dissipated, or at least half of it. His eyes opened wide once more. The combination of my mother's healing magic and my leaf of life resulted to be rather powerful.

"Ahh… Eh? I feel better…" My father sighed, as he slowly stood up.

"Eat another!" I said.

"Huh? Just what are these?" He wondered, eating a second leaf. He quickly felt way better.

"It is something that Sylphy has been hiding from us, apparently one of her Spirits can produce those leaves!" My mother said.

"What?!" My father asked in surprise. "A spirit that produces an item… Now that's something new. And your spirit too, the fire one… What's going on in here?"

"Ah, well-"

TRUUUUMMM…!

Before I could even explain things properly, a tremor shook the ground.

As we all desperately looked into the direction of the sudden tremor, a shockwave of mana and another dangerous energy emerged, clashing against my mother's fortress.

CLAAASH!

From the skies, several magic circles appeared, three of them, in fact. They were strange, not like the normal magic circles of this world, but had weird runes and shapes, such shapes which I have only seen that time when we had to fight a True Demon summoned in front of this town's dungeon.

From within those three magic circles in the sky, which I will now name Demonic Circles, three enormous figures emerged. They were overflowing with red and black essence, resembling monsters I had… never seen before. All three of them were humanoid in appearance, and their mere presences created that shockwave that impacted my mother's Light Fortress.

"Those are True Demons?" Asked my mother.

"Three of them! And they look to be stronger than anything we fought before in here…! Ah!" My father quickly realized something. "Those are Demon Dukes…!"

"Demon Dukes?!"

Apparently, demons had ranks based in levels of nobility, Dukes were obviously incredibly powerful, as they governed over a piece of Land. These guys might as well be just that. Perhaps they even governed over their own land before being summoned here!

"So this was the ultimate endpoint of these cultists, bringing these absolute monsters! They'll end up wiping out the entire city if we let them do as they please!" Ninhursag pointed out.

The three figures quickly looked down on us specifically, as if they knew we were talking about them. All three of them looked demonic and monstrous in nature. Their appearances were also humanoid, and the smallest of the three was as tall as six meters. I quickly noticed they were even wearing clothes that seemed to mimic nobility's clothes. There was a tall female and two males.

The female resembled a beautiful woman with red skin, sharp horns growing over her head and shoulders, alongside a monstrous jaw with many sharp claws in her stomach spoke. Her stomach opened, showing a long tongue waving around as if it were ready to devour us. Her long black hair and her sharp red eyes made her resemble a beauty of the depths of hell. And her long, red dress seemed to go with the rest of her skin color.

Suddenly, several other magic circles emerged around the entire place, as if it was all shaking, several red-skinned monsters emerged one after the other constantly, dozens of True Demons. But they didn't attacked first, they looked into the skies, astonished to see these three Demons.

"Ooohh!"

"But if aren't those… The Dukes!"

"I can't believe it… they're here!"

"It is an honor to be able to delight ourselves with the flesh of these mortals with their presences!"

It was as if their very existences were way above the others.

"So many more demons! What is going on?!" Ninhursag asked in shock. "Did these Cultists really had enough souls to go this far?!"

"Bastards… there are dozens… dozens of true demons!" My father said.

"It feels like…" My mother muttered. "We are being sacrificed to them. Look at their smiles. I've always hated True Demons. They're fearless and cannot feel any cowardice at all. They have no fear of their lives and are worse than monsters themselves."

"And those three atop the sky are bad news." Agni said. "Now that I've switched sides, I'll have to fight these buffoons, huh? Well, bring it on!"

The Demon Woman slowly flew in front of the other two who remained in silence. It seemed she had some higher authority than them.

"Welcome, my dear guests! I have heard from the Gatekeeper of Dimensions that you were the "Heroes" of this world, is that right?" She asked with a smile. "Would it be alright to introduce ourselves?"

As she heard no response, she giggled.

"Are you all so scared?" She asked, while flying around, suddenly beginning to spin over the sky as her enormous jaws in her stomach began to move its long and disgusting tongue. "Don't worry, you've finally been given a fitting end to your pitiful lives! Please, smile!"

"Smile?! What is she even talking about?!" My father said, fury clear into his eyes.

"My name is Lilith, I am the Duchess of the Fourth Infernal Gate, and one of the concubines of my beloved Lucifer." Said the woman. "I have been summoned here for the purpose of bringing torment, suffering, and bathing in your blood! And oh! By all means, please! Let me bathe in your blood!" She said, beginning to caress her entire body with her hands seductively, a smile filled with lust and desire emerged in her face as her second jaws began to drool, the long tongue beginning to move around playfully.

"Lady Lilith."

One of the demons behind her spoke.

"Ah, yes…  might as well introduce you to my two retainers, yes?"

The True Demon crowd quickly went insane again.

"Oooh! It is Lady Lilith and her retainers!"

"Her two servants?!"

"How honorable is to fight with them at our side!"

Lilith laughed at the excitement of the other True Demons.

"Let me introduce them to you, Berith and Astaroth…!"

The two demons flew forwards, showcasing their enormous auras…
