The Game Rune System

The demon woman, Yurishia, didn't have much time to think about it.

However, it was highly unlikely for Tetsuya's powers to be potent enough to completely control her.

That was why she took this eroge game and became the player.

[You have completed the first eroge quest - Trust Your Prince!]

"..." The demon woman's eyes narrowed as she spotted that the first quest got completed upon her accepting this game.

There were two rewards: kiss from charming prince and Red Yin Demon Essence.

While the first one was completely ignored by the woman, the second pulled her eyes and she raised those to question Tetsuya, "You can pass it to me?"

Her eyes got hazed with lust, but while Tetsuya would gladly exercise a little with this woman, he also couldn't be that easily achieved, could he?

It should be also dangerous to have a ride with that woman and Tetsuya couldn't risk anything for now.

"I can just pass it through handshake," Tetsuya smiled as he replied.

He still needed to make some contact and limits and this was the perfect answer.

As Tetsuya came closer, he extended his hand, "I will be in contact with you through this eroge game. Let's say you have to be at least in the neighboring province of Yulia Household for me to contact you," Tetsuya said, then the demon woman shook his hand.

"That is the yin demon essence I have never felt. Ahhh…" She moaned while clenching Tetsuya's hand.

Tetsuya wasn't even surprised by her skin as it just felt good. Her hand seemed boneless and was really soft to hold. Just by holding her, Tetsuya could tell that difference between the human and lustful demon.

Soon, Yurishia's ecstasy calmed down, her eyes looking at Tetsuya who had begun to sneer at her widely.

She shivered a little from his smile, then said, "Let me present you with something too." Her hand swept, then purple tendrils began to gather around Tetsuya's wooden sword.

Those didn't seem dangerous, so Tetsuya just kept a close eye to his sword. As those began to coil around the blade and hilt, Tetsuya suddenly began to feel change.

It was as if lustful demon's bloodline origins began to reveal itself within him.

Though he didn't have bloodline, Tetsuya could use this Romantic Swordsmanship as well, so who knew what was actually going on here!

The wooden sword became as if swallowed in bud, then it soon bloomed with bright light.

What came out from it was the steel sword that had purple hilt. It was decorated nicely with rose and seemed stronger than before.

"Now, you gave a rather too good present," Tetsuya smiled, his sword already raised to look at it closely.

Yurishia sneered, "It's just a part of the power hidden within. But I erased the influence of another demon too."

"Influence of another demon…" Tetsuya narrowed his eyes. He couldn't tell that there was something like that within.

His countenance explained his inward thoughts to the demon woman. She said, "This sword is a weapon good against women and men. For women, you trigger their yin qi and make them wound from inside. As for men, you forcefully implant yin qi by wounding them and reach the similar effect."

"Thanks for the explanation," Tetsuya smiled genuinely, then the demon woman turned around, showed off her beautiful ample ass, then disappeared from the sight.

The women in this room were beyond help, so Tetsuya just closed his eyes and decided to inform Yara Yun about his finding.

While going here, Tetsuya whispered, "You wanted me to kiss that demon?"

"I just played a little here, hehe! I didn't expect her to go for the kiss anyway!" Ashley covered her lips and laughed in a lady-like manner. Even though it was a kiss for another woman, she still went for it and even enjoyed the eroge game.

As supportive as she had been, Ashley truly showed Tetsuya how much this world differed from his first one…

Tetsuya sighed, "I will have the eroge game controlled by you. Keep an eye on the demon woman."

Giving games to others didn't seem that bad, so Tetsuya already began to form some plans. Though all moderators would need to know at least the basics, it would be fine to have people specialized in one type.

[Lust Sword]

"Lust Sword sounds so simple, but it's going to be a fucking revolution in my strength," Tetsuya laughed and his partner understood him.

The whole world was their goal! Just how many women and adventures they would be on? How many races, hidden from demons' eyes, would enter Tetsuya's eyes and allow him to snatch their yin essences and turn them into unique demon ones?

Tetsuya was a man who would meet a lot of people and his Lust Sword might bring out a lot of yin power in the future.

Even the combination would be possible!

"It seems like Yurishia isn't particularly close with the demon in Yulia Household! If I had to guess, then one of the patriarch's wives must be under the cover!" Ashley said her theory and Tetsuya approved it on the spot.

Lustful Demon wouldn't give up on a strong sword and by having this seat she would be able to learn most of Yulia's Family patriarch's goals and his motives. She also would have easier time controlling things in case those would go against her way.

But Tetsuya had to comment on something, "Are all humans friends?"

"Eh? Of course not," Ashley replied.

"And that's how it is with the demons. We gotta leverage all we can and just make them dance in our games later on." Tetsuya smiled.

-

"So this is where you had been hiding…" Yara Yun stood above the certain mansion.

This mansion used to have a demon here that would search out for possible rich in yin qi essences. Of course, yin qi because it was a woman lustful demon!

This meant that her daughter could be one of the potential prey.

Though Yara Yu was already an adult woman, Yara Yun treated her still like a brat which was what most mothers did secretly to their children.

And Yara Yu was still not as experienced as her mother, so her age didn't matter; she could be one of the easiest prey.

From afar, Tetsuya had been looking at Yara Yun ever since she floated up into the sky. Using one of her runes, she could keep herself here and look like the real goddess on the moon background.

Her hair fluttered gently, but as the runes began to emerge out of her body, she suddenly turned into a ferocious goddess.

Nothing seemed calm around her anymore.

Even her eyes became narrowed and glazed with viciousness.

"Shit, this brings some memories…" Tetsuya uttered.

"Yes…" And Ashley responded.

The runes emerged out and those were all elemental runes.

One of those elements was a fire rune that was like mini sun circling around the ferocious goddess' body.

Was perhaps Yara Yun one of the people that could help Tetsuya prepare for that inevitable clash?

For now, Tetsuya didn't think of going against those monsters anyway.

He just raised his eyes, looked at the elements somehow blending with each other, then like an avalanche, descended upon the mansion and all its people.

It was sad, but no one was spared. Even if there was a part of the family that wasn't aware of this connection, they all got swept by the elemental avalanche and destroyed rather instantly by it.

Ashley raised her voice, "Rather than stern, she is merciless… Look, Tetsuya… Some people are escaping here."

Obviously, no one of the allies were close to that mansion.

All of them were scattered around it in case any people dared to run away from their punishment.

Tetsuya took out his lust sword, raised his eyes at the incoming people, then killed them all just like Yara Yun wanted him to do.

He continued to keep an eye on his surroundings for an hour more, even if the elemental avalanche already had ended.

-

"Welcome back, Tetsuya," Yara Yun greeted Tetsuya while sitting on her chair comfortably. She was more like laying on it and her legs were stretched out.

She was far more comfortable around him, even more after the demon's influence had been confirmed on the recent avalanche's victims.

Just a few minutes ago, Yara Yun ended writing a letter to the person in the wasteland in the north.

She had to be very formal and respectful, but now she could just ease up and stretch after all hard work.

Though her eyes no longer seemed vicious, Tetsuya still could see a faint viciousness within, "Mother in-law should relax more. I can't stand those eyes."

"What eyes?" Yara Yun probed.

"Eyes that are the farthest from what I had been seeing so far." Tetsuya closed up the distance and arrived before mother in-law. He then put his hands on her shoulders and began to massage those.

He could see a special ink and pen on the desk, so she must've been writing a lot for now.

"Mother in-law should relax and forget about everything. Then, I want to get spoiled by my mother's gentleness and beautiful and pure eyes."

"I will," Yara Yun already felt more relaxed and Tetsuya's massage couldn't be better. He had good hands and she soon fell asleep while leaving herself totally defenseless.

Tetsuya smiled, put a blanket around her sleeping body, then left the room in a silence.
