Festering Desire

Runes are the written language of Anima, like how math is the language of physics. Manipulation of energy flow and arithmetic of runic scripts were essential to the formation of runic spells, which were the skills that Leo always lacked.

Hence currently, with their naked bodies, the twins were attempting to educate their young master on the proper techniques.

Do not question why a little demonstration from the grimoire required them to strip, Yuria and Filia had their own ways of teaching. Perhaps a visual showing was a physically more effective way to get hold of the boy's attention; and it had been very successful thus far, his eyes were pasted with undivided attention on the studying materials.

"Me and my sister possess two different types of Anima, but are also compatible with each other. With our energies channeled together, blending them like Yin and Yang, it becomes exponentially easier to construct various runes." - Yuria

Soon, the embedded runic scripts from the grimoire manifested on the twins. Following similar logic of zeros and ones on a computer chip, the twins were able construct more sophisticated designs of runes.

"We can selectively activate and combine certain runes on both of our bodies, easily forming the patterns that we dictate. Watch closely." - Filia

Leo *very closely* observed the glowing lights on their transcalent skins flowing from one region to another. However, he did not notice with each different combination of runes that lit up, a runic circle appeared near one of his limbs. By the time his mind returned from the enchanting sights, he was already bonded to the ground.

"Wait, what did you two do? Where did the seals come from?" The boy never expected the spells could latch onto him from different angles; he only knew how to activate runes from the ground.

"It's just some basic techniques. Now, young master, can you break free of our binding without brute forcing with your power? You are only allowed to disrupt the circulation of Anima within these runes by altering the current with your own." - Yuria

"For your training, let us play a game. If you climax before you break free of the binding, the young master loses. But if you were successful before then, we will tell you a secret about our elder sister." - Filia

"We will let you do anything you want with our bodies too, but if you lose... we get to have the young master all for ourselves tonight." Pressing their melons onto his arms from both sides, the twins teasingly lifted the dangling beast with their hand and seductively whispered into his ears.

The boy was unable to move an inch of his muscle due to the runic seal, and could only helplessly watch Yuria and Filia stroke on his erecting rod and toyed with his body however they wished.

But hmm... this didn't seem like a game he would lose no matter how it would end up.

Eventually, under the guidance of the twins, Leo managed to break free of the seals with just the control of Anima alone; but unfortunately, the wall before him was already covered in viscous white splatters of thick paints, adhesively dripping down from its surface. It was his complete utter defeat; the boy supposed he would have to make up for his loss in bed.

-------------------------

But the lesson, of course, did not end with a single ejaculation. There was still much to learn for a young little boy that was newly introduced to the proper education of runic cultivation. After attempting the trial for a few more rounds, the wooden wall was almost crumbling from the constant bombardment of his ravaging torrents.

In the meantime, the runic spell that seals the arch demon's power was finally placed on him; it was a more flexible and less restraining version. However, there was a single drawback.

"For the young master to sustain the runic seal yourself, you need to gather different types of Anima to blend in with portions of your life force. They can help maintain an equilibrium for the seal, even if it's temporarily." - Yuria

"The simplest way is to perform the holy deed with our sisters. As generous as were your blessings, a small amount of their Anima would be absorbed in reciprocation. The young master seemed to be compatible with any type of Anima from women. - Filia

"They also will come handy when mastering the runes. If the Young master truly wish to learn more about the art of runic spells, we recommend the academy of Laya Rucaria."

This was the second time Leo heard the name of the academy, and it has begun to pique his interest; especially after learning that his mother was a graduate of that school.

The academy of Laya Rucaria was built almost three decades ago after the great awakening; a national institution that gathered Anima users around the country to research the lost knowledge of the supernatural world.

Ancient writings that used to be considered as superstitions and religious myth were now the core curriculum of its classes. Many of them are quite popular on the market after a quick re-branding, like "How to be a witch 101, a guide for female cultivators", which was an excerpt from the holy bible the 25th edition.

The founders of the academy had a lofty goal of awakening every citizen in the country into Anima users. They had been trying to formulate a cultivation technique where normal people could practice and awaken themselves through hard work.

As the awakening was only fairly recent on the grand scale of history, and more and more Anima users are being awakened every day, countries were still trying to standardize the practice and common knowledge for cultivation. Given the trend of ever-increasing Anima density in the world, the process was accelerating due to public demand and concerns for national strength.

--------------------------

Meanwhile, back at the town's hospital, within a certain chamber of the hidden realm, Yurin was checking up on her baby girl with the main company of the cult.

"Madame Shouko, your daughter is still quite a glutton even in her hibernation. Have you devised a way to keep her under control for when she wakes?" The boss glanced at the pile of dried carcasses beneath the nest of gore; the aura emanating from the cocoon was growing stronger everyday.

"The bond is still secured, there is no need to worry. Just keep feeding her, then maybe she will be familiarized with the scents of her meal providers." Yurin hid her grin behind the sarcastic remark.

The woman held an important role within the cult because they thought she still possessed the blood seal that could influence their divine weapon. It was her biggest bargain chip after she donated her daughter to the plan. However, little did they know, the seal was easily broken by Komi's own will when she submitted to Leo as her master.

The big girl was only pretending to be docile because she recognized Yurin as her mother. If the organization had trouble keeping her under control before, then they would have struggled more after her evolution.

"But our hideouts are getting taken out one by one, as if the government knew exactly where we set up."

"I see, this is indeed troublesome." The woman was more focused on her daughter's state, unconcerned of the cult's troubles.

"Even the monolith we hid in the forest was destroyed. We won't be having any more scavengers arriving for a while."

"Oh? That is certainly unexpected. Who could have seen through the barrier I set up?" Yurin was genuinely surprised by this news.

"Indeed... I wonder who..."

In that instance, the boss slid out a knife from his sleeve and swiftly stabbed the woman behind her back. With the blade piercing all the way through her stomach, her eyes widened as she speechlessly watched her blood tainted with black inks spill from the wound. Yurin understood right away that she had been exposed, her only question... was how?

"You think I wouldn't have noticed, but if it wasn't for the collapse of the monolith, I would have never thought the traitor was you."

Runemasters were vital strategic resources even for the government organization; they were all high priority targets under the watch of the cult headquarters and none of them were remotely close to the area.

There was little chance for anyone around the town to dispel the barrier, other than the runemaster, Yurin herself. This was where the suspicion started even if it was just a possibility; but the doubt led the boss to discover the truth after a secret investigation.

Even though the monolith's collapse had nothing to do with Yurin, she could only sigh for her bad luck as she immediately sorted out the logic behind the boss's reasoning.

"To think you amongst all others would betray the organization, but to traitors, there is only death."

Regardless, as her consciousness slowly faded due to her wound and the lethal poison on the knife, the mother took one long last look at her daughter resting peacefully within the transparent membrane. Gazing at the goddess's serene beauty and impeccable form, a hollow emptiness was felt in her heart.

But there was one thing that lingered... and it was the regret that she had as a mother.

"I am sorry, Komi..."
