Breakthrough, level 6!

. . .

After he left Emiya residence, Ryan sneakily went toward the underground cavern under the temple; he was going to the place where Avenger manifested itself.

When he finally arrived at its depth, Ryan was greeted by a cold voice from the front,

"You've finally come."

Ryan's doppelganger laughed strangely as he turned around. His face twitched, he was torn between laughter and crying as he trembled violently.

From his eyes, Ryan could see that his doppelganger was almost fully consumed by insanity.

"These resentments, curses, evil wishes of the world and all creatures… the immense mana of the Greater Grail… I almost couldn't hold it any longer waiting for you."

Ryan went toward his doppelganger with grim look. He patted his shoulder strongly, "Good job, mate. Thanks for holding on for so long, and leave the rest to me."

A small smile appeared on his face as Ryan's doppelganger turned into a group of black smoke, covering the whole underground dark in their shadow.

With him in the middle, those black smoke were soon absorbed by Ryan as he exercised the Demon King Arcane Art furiously, going plus ultra and exceeding its full capacity.

His Demon King Arcane Art was advancing fast the more Ryan refined those black smoke.

[Demon King of Domination Arcane Art (level 5 – Soul Transformation) (30%)]

[…(35%)]

[…(45%)]

[…(60%)]

[…(80%)]

[…(100%)]

At some point, when he already devoured half of the black smoke, his Demon King Arcane Art reached a critical point of breakthrough.

"Ahh!"

At same time, the evil wishes, curses, and resentments from the world and all its creatures were flooding into his mind; they were trying to corrupt him.

Artoria who was immersed in her own practice suddenly felt a negative feeling started haunting her calm heart. As she didn't have any contacts with outside world during these periods, she immediately thought about Ryan who was outside.

'…stay safe. I am heading there soon.'

Artoria looked stern as she left the hotel room in a flash of blue light.

In her wake, the room was full of frozen icicles and frost on its wall and furniture, as though a snowstorm just happened inside the room.

'Shit! This is too much indeed!'

Ryan thought in silence when he was immediately surrounded by even more evil wishes, curses and resentments.

His situation was different from Gilgamesh who only touched the surface of the entire thing. That time, Gilgamesh was immersed inside the black mud. However, this time, Ryan was trying to engrave the concept of the All the World's Evil into him.

With the immense mana stored inside the Greater Grail as the burning wood, and Angra Mainyu as the catalyst, Ryan was trying to turn himself into a true Demon King through the Demon King Arcane Art.

Although, with his mind fully focused on absorbing the black smoke and defending his mind from the corruption, Ryan couldn't help losing his awareness to his surroundings. He didn't realize that another figure had appeared at the entrance of underground cavern at some point of time.

Soon, another figure also appeared beside the first figure. The second figure looked shocked at the sheer of evilness emanating from that place, and clad herself in a cover of furious lightning.

"Ruler, Jeanne d'Arc, do you happen to know what kind of abominable place this is?" Raikou frowned as she looked at the thick miasma of evil intents in the underground cavern.

She was originally tracking Jeanne d'Arc after she realized that Jeanne was following Ryan. However, when she finally arrived at their destination, she became extremely alarmed instead.

In front of her, she saw a dense cluster of evil miasma that could even corrupt Servants was hiding unnoticed by other Servants in this underground cavern.

If this miasma were released when they were fighting... God knew what would happen to this city…

Jeanne looked sad. It was after seeing it for herself that she understood just what kind of thing Ryan wanted to do;

He wanted to bear all the sins and evils in the world unto himself, becoming the true All the World's Evil.   

"This is the sins of the world. It is not something he should carry nor it is something meant for him."

A thought occurred to Raikou when she heard that, "Him? Ryan? Is he there?!"

She felt slightly worried for him.

If these evil miasma could even corrupt the Servants, no matter how strong Ryan was, he would also become corrupted if he stayed there long enough.

In a while, Jeanne nodded in silence.

Leaving the stunned Raikou behind, Jeanne raised her flag bearer and tried to pass through the thick layers of corruption smoke as faint golden light enveloped her.

"Please don't enter this place, Minamoto no Raikou. If not, you'd also be corrupted into something you don't want to see.

"I am a special case, as such, I will help him."

Jeanne d'Arc braved through the evil miasma of All the World's Evil under the protection of sacred light emanating from her flag bearer. As she walked through the fiendish and evil intents, her steps were steady and firm.

Her eyes were filled with resolve as she looked toward the kneeling figure in the center of this evil miasma.

'You shouldn't impose that much evil unto yourself. That is not the kind of burden you should carry.

'*sigh*…I don't know what that revelation actually meant, or what I was supposed to do to you.

'However, if you really fall here, a hell shall be unleashed in this world.'

Killing Ryan at this point would not turn the situation into anything better. If anything, without a focal point for them to gather, the evil miasma would spread across the land and brought an even greater destruction.

That was not something Jeanne was willing to see.

Yet, if Ryan was corrupted by these evil contaminations, he would also become a catastrophe for the world.

Both options were equally disastrous.

Knowing that, even if she was to sacrifice herself, she would make sure that Ryan wouldn't fall to the contamination. Only by reaching a balance between good and evil that he would be able to retain himself...

"[Luminosité Eternelle: God is Here With Me]."

A sacred barrier was erected in the middle of these evil miasma. Its light brought a flicker of warmth amidst the bone-chilling evil intents all around the underground cavern.

Jeanne embraced the young man kneeling on the ground who was trembling in pain and rage.

She whispered gently to him, "Resist them, young man; those impure, wicked whispers of this world's sins... Stay true to yourself." 

At that time, Ryan was feeling like he was plunged inside an abyss of despair, resentments, curses, and all sorts of evil wishes. They tried to pull him deeper and deeper into a devilish paradise; to mould him into another person entirely.

Although this was already the case after he used his doppelganger to filter some of the evil intents, even the remaining evil intents almost drowned him completely.

It was no wonder that his doppelganger almost fell into insanity before...

Yet, at such time, he suddenly felt a pair of warm hands casted the darkness away from him and took him into a gentle embrace.

Those hands felt familiar, yet also unfamiliar at same time. Even so, since it was the first time he tasted such warmth in this pit of hell, he yearned for more.

Ryan tried to grab those 'warmth' close to himself, as though he wanted to melt them into his being.

However, it seemed like the owner of those warmth was startled. They were getting away, which prompted him to forcefully grab them.

Like a child who finally got his favorite toy,  Ryan wouldn't let them go no matter what. He cuddled, caressed, and kept them close to him so he wouldn't lose them.

In fact, at that moment, Jeanne d'Arc was having a dilemma...

If she moved, he would go berserk and sought her out no matter what. He wouldn't calm down if she left him even for a moment.

Yet, if she didn't move and just accepted whatever he did to her, the embarrassment was too much to take for her!

Her upper clothes was already torn by the young man, revealing her pearly white skin hidden under her battledress. She was practically naked on her upper body.

One of her pair of enchanting breasts was fondled and caressed by him, while another one was sucked gently by him like a kid breastfeeding on their mother.

His other hand was roaming on her back, going from her neck, slowly gliding down to her torso, then her bottom...

She couldn't help feeling slightly aroused as he kept fondling her body.

Although she was so embarrassed that she could die, she still stayed beside him because she could see that the evil miasma in their surrounding was thinning out rapidly.

This young man still persisted to absorb those evil miasma while he was harassing her.

"Ah! Not that...place... Ehn!"

The young man's hand had suddenly slid into her innermost part just now. His finger moved around that place, being gentle and rough at times.

In this silent and cold place, hearing those lewd sounds when his finger made a mess of her innermost part was quite a stimulation for her.

Her feeling was messed up even more when she felt a wave of pleasure coursing through her. She felt that her body was gradually becoming more heated by the seconds passed.

"No! I wouldn't succumb to this...! Wake up, young man!"

Jeanne pushed him away in the heat of moment.

She covered her enchanting pair of breasts with her left hand as she admonished him, "Don't let those evil thoughts control you. You should be the master of your own self!"

Although, Ryan seemed like he was unable to understand her. His eyes already turned black, his body was wrapped tightly by the evil miasma, his reason was replaced by instinct.

Feeling that his 'toy' had moved out of his reach, he went berserk. Like a beast leaping down on their prey, he pushed Jeanne down to the ground.

"Rrawrr!"

His hands held her shoulder strongly that deep marks appeared on her pristine shoulders.

His other hand teared her skirt, removing the last piece of clothing hiding her beautiful figure.

As he was reaching out to her flowery pot, he heard a gentle and soothing voice calling out to him once more,

"Please, come to your senses..."

His hand stopped. For a moment, when he looked at his 'toy' again, he seemed to see the image of Artoria on 'it'.

"Argh...!!!"

Ryan held his head tightly as he felt pain all over his body. The insanity within his eyes was also reduced by a notch.

"Artoria? No... You are not her... Who are y–!!!"

Even so, as the trace of sanity appeared on him, it also quickly vanished. His eyes turned black once more as his reason disappeared again.

Ryan grinned evilly as he looked at the beautiful 'toy' in front of him.

Yet, just as his hand reached out to Jeanne, he seemed to feel someone else blocked him.

Ryan seemed confused when he turned to look at a new 'toy' that suddenly appeared. Even if his reasoning had vanished, his instinct told him that this 'toy' was dear to him...

"Geez. Don't trouble the holy maiden, Ryan. You should have called me if you want to do this kind of dangerous matter again.

"Honestly I prefer to do this while you are awake and at a more romantic place. But, looking at your current situation, it would be asking too much.

"I have sealed the entrance of this underground cavern, so no one would disturb us. Therefore, come, unleash your desire on me, Ryan."

At that moment, he had decided to play with this new 'toy'. He abandoned the thought to play with his previous 'toy'.

In the underground cavern, under the cover of evil miasma and witnessed by the embarrassed Jeanne, Ryan took Artoria roughly as he plowed through the verdants plain and lofty hills throughout the night. 

"Wha– so shameless!"

Jeanne closed her face with her hand, though there was a wide gap between her finger that allowed her to peek at Ryan's and Artoria's intimate act.

Her face was burning red hot as if she got a fever.

Seeing their entranced face as they were engrossed in their act, Jeanne felt the heat, which had previously subsided, was roused once more inside her.

At that moment, Ryan seemed to feel that his previous 'toy' was quite pitiful. To be neglected after he got a new 'toy', he just couldn't help feeling wanting to give some affection too...

After he finished playing with the new 'toy', Ryan went toward his old 'toy'. He couldn't be biased to only favor one side, right?

Yet, when he just took a step toward it, his gait stopped. He was held again by his new 'toy'.

"Aren't you underestimating a dragon's vigor?"

He didn't know how he was pushed down by his new 'toy' just now, but he felt that it was not that bad sometimes.

"Brace yourself. I will thoroughly drain you tonight, my dear demon king."

Artoria Lancer looked quite lewd as she smiled while straddling him on top. At that time, she seemed to glance lightly at Jeanne d'Arc. 

'Ahh! What's with her smirk?!'

For some reason, Jeanne felt a bit annoyed seeing Artoria's smirk just now.

Artoria then dismissed Jeanne as she focused on Ryan again. She went on the offensive, though Ryan also responded with equal ferocity. After all, he didn't want to lose to his 'toy'.

That night, both combatants were fighting fiercely for many rounds without much of a pause. After they rested for a bit, they immediately went toward each other as they continued their 'battle', soaking in endless pleasure as they fought fiercely with each other.

If anything, it was the spectator of their 'battle' who felt quite agonized throughout the night...

At dawn,

The entire evil miasma had finally disappeared from the underground cavern.

Also, Ryan was finally awake as he regained his senses, having finished absorbing the entirety of the Greater Grail's mana and Angra Mainyu.

Though,

After seeing the two naked bodies in front of him, no matter how strong or smart he was, Ryan was still flabbergasted at how things had reached such a point...

"The... Heck? Did I just have a threesome here last night??"
