Want to play cards? I'll use my King's Deck!

The first card revealed was "Dark Witch - Diabelstar", which had been obtained in the Trial Duel.

A lot happened today, but he still has one last thing to do.

"Then let's test my hypothesis."

Yuki activated her Duel Disk and placed the "Dark Witch" card on it.

The 3D imaging system immediately started operating, with light and shadow shifting and outlining the erotic witch wearing a black hood and a red demon mask, possessing a rather voluptuous figure.

Upon appearing, before even receiving any orders from Youxi, the Black Witch suddenly raised her arm-length dagger and pointed it at Youxi.

Those lively eyes and movements are an effect that a simple 3D imaging system cannot achieve.

Just as You Xi had expected.

“Miss Belle…you really did bring the card along.”

"Damn it! Do you think I wanted this?! That damn trial didn't even ask me before including me! What do they take me for, you bastard?! This is human trafficking! Human trafficking!"

Yu Xi was fine until she mentioned the Black Witch, and she immediately started yelling excitedly like a cat with its fur standing on end. Fortunately, the room was soundproofed, so it wouldn't disturb the other girl she was living with.

After grumbling and cursing for a long time, the Dark Witch finally remembered what she had been planning to do.

"Wait a minute, come to think of it, why aren't you scared at all? I've already pulled out a weapon and pointed it at you, shouldn't a defenseless human like you show some fear?"

"Because Miss Bell, you didn't intend to kill me."

Yu Xi replied, "I'm quite sensitive to other people's emotional changes. Miss Bell just wanted to scare me, am I right?"

"That's hard to say."

The Black Witch gave a mysterious smile, neither confirming nor denying, and said in a dangerous tone, "Perhaps I really am planning to attack you. After all, if I can finish you off here, I might be able to gain my freedom and return to my original world."

"That would have to be something you, Miss Belle, can do."

In the time before summoning the Dark Witch with the Duel Disk, Yuuki had probably figured out some things, so she simply exposed the Dark Witch's true nature.

“If Miss Bell could do it, she should have done it before. Since she didn’t, it’s not that she didn’t have the intention to kill, but that she’s probably bound by some kind of restriction, such as not being able to materialize autonomously in the human world.”

"It's only able to show its form now thanks to the Duel Disk's 3D projection function. If I take the card off, it'll probably disappear immediately?"

"Gu...!"

—That was absolutely right.

The Dark Witch is now fully aware of her situation.

Unlike in her original world, she found herself severely restricted upon arriving in this world. She couldn't materialize freely, and acting alone required consuming significantly more Feel power.

More importantly, she was now completely bound to the boy in front of her.

Youxi has now become like her master, and in reality, he has no way to harm her.

All we can do is bluff and intimidate them like this.

However, the Dark Witch was very unwilling to accept this.

Damn it!

Being defeated by a human duelist is bad enough, but to be captured by them is utterly humiliating!

What legendary thief would have such a humiliating experience? It's probably only found in those little notebooks.

Hmm, wait a minute... Isn't this development exactly the same as in the little notebook? So, is it possible that this human master is going to do whatever he wants to me next?

No, that kind of thing absolutely cannot be allowed to happen!

"So what if you guess right? Don't think you can use that to blackmail me."

Thinking of this, the Black Witch glared fiercely at Youxi and emphasized, "I can't hurt you right now, but the reverse is also true; you can't do anything to me. I will absolutely not submit to you, you despicable human!"

"No, I didn't intend to do anything to you."

I have a feeling that the black witch in front of me is thinking about something strange.

You Xi didn't voice her inner complaints, but instead said, "Miss Belle, I called you out today for two reasons. First, I wanted to confirm that you really came back with me. Second, I wanted to have a proper talk with you."

"What to talk about?"

"Whatever we talk about, could you at least put your weapon down first?"

Yu Xi gestured to the dagger still held by the Black Witch, and after she sheathed her weapon, he continued, "In any case, Miss Bell has already returned to this world with me, and there's no use being angry. Now, can you still return to the Elf Realm, which is that other world?"

"Nonsense, of course not."

The Black Witch plopped down on Youxi's bed and rolled her eyes in annoyance.

Although lacking the support of Feel and dark power, the Dark Witch cannot materialize, but the 3D imaging technology still gives her a certain tactile sense.

"If I could go back, do you think I'd still be this angry? I'm a prisoner, you know. I've never heard of prisoners just wandering around like that."

"Is that so? Then let's cooperate, Miss Bell."

Yu Xi earnestly proposed, "I'll find a way to help Miss Belle return to the Elf Realm. In exchange, until this agreement is fulfilled, how about I lend you my power, Miss Belle?"

"So that's it. What they coveted wasn't my body, but my power," the Black Witch suddenly realized.

"Hmph, you have pretty good taste."

"After all, Miss Bell's strength is indeed very strong. I have experienced that firsthand."

The card "Dark Witch - Diabelstar" is the core of the "Sinful Treasures" series, without exception.

Before Yuki traveled through time, it was right in the early stages of DogK Company launching this brand new card story.

Based on the experience of "Teaching", "World's Destruction" and other large-scale card stories, it is known that there will be many more new cards related to "Dark Witch" in the future, showing great potential.

Even though she can no longer continue the original card story and obtain those new cards because she was accidentally kidnapped, "Black Witch" is already strong enough and is a very high-quality add-on.

If possible, Yuki still wants to integrate the power of "Black Witch" and "Snake Eyes" into her deck. These are truly turbulent times, so any increase in strength would be a good thing.

However, "Dark Witch" is not an ordinary card; it is inhabited by a card spirit. If the spirit itself doesn't cooperate, it will be difficult to use it normally.

Therefore, he needs to reach an agreement with the Black Witch here.

“I’ll lend you my power, and you’ll help me return to the Elf Realm. That sounds like a good offer, but how can I trust you to do it? You’re just a student, aren’t you?”

The Black Witch was initially pleased with Yu Xi's compliments, but after regaining her composure, she also raised her own concerns.

The vast majority of Duel Spirits have long since separated from humans, residing in different dimensions, separated by a thick dimensional barrier.

Sometimes, there are indeed gaps, like trial cards, that temporarily connect the spirit world and the human world, but those gaps are not enough for her to return.

While in card form, the Black Witch also learned some of Yuki's situation. Given Yuki's resources, the Black Witch didn't think Yuki could find any other way.

"But Miss Bell has no other choice but to trust me."

Yu Xi remained unmoved by the Black Witch's doubts and said, "We're in the same boat now. Besides me, probably no one else would be willing to help Miss Bell, and I do have some relevant clues. Miss Bell, you don't want to stay in the human world forever and never be able to go home, do you?"

"Gu...!"

The Black Witch's expression changed after her weakness was exposed, and her gaze toward Yu Xi turned sinister once again.

"As expected, I still really want to beat you up!"

This guy looks harmless, but he's still really awful.

"In short, that's roughly how it is."

Yu Xi extended her hand, a symbol of "friendship," towards the Black Witch.

"So, Miss Belle, let's fight side by side."

"Tch, it seems like there's no other choice besides this."

The Dark Witch curled her lip.

Even though she was unwilling, she had to admit that You Xi was right. In the present moment, when she was bound to him, only You Xi had the potential to help her break free from his control.

In the process of searching for the passage to the Spirit Realm, there will definitely be many battles, and I naturally cannot stand idly by.

"Alright, let's form a united front for now."

The Black Witch reached out and shook hands with Yu Xi.

With this handshake, an unseen connection seemed to be established.

In novels and anime, this would probably be the perfect moment for a narration that says, "This is where the legend begins."

But the Dark Witch then said, "However, let me make this clear beforehand: this legendary thief is not a servant you can order around. I won't show up unless it's an extremely important occasion. Besides, my patience is limited; if you take too long without making any progress..."

"It's alright, this is enough. If everything goes smoothly, I think we should have results within six months."

Yu Xi didn't care much about the Black Witch's diva-like behavior. Anyway, he usually used the King's own deck to play cards in order to use his golden finger to print cards.

The fact that the Dark Witch can appear at crucial moments is more than enough.

Having finally gained the Black Witch's approval and resolved a worry, Yu Xi was finally able to relax.

But as soon as you relax, all sorts of feelings of fatigue come rushing in.

This made Youxi unable to control her overwhelming sleepiness any longer.

He yawned widely and said to the Black Witch, "It's getting late. Let's discuss the rest tomorrow. I also need to introduce you to Miss Xingye. Goodnight, Bell..."

"What's wrong? Why did you suddenly stop talking?"

You Xi suddenly stopped speaking, and the Black Witch was puzzled.

"No, it's just..."

Yu Xi looked at the Black Witch still sitting on her bed, her expression somewhat subtle: "I suddenly thought of something. Miss Bell is an elf, right? Do elves need sleep? Also, where do you usually sleep? In your cards?"

"Of course it's in the card, otherwise where would it be?"

At first, the Black Witch was a little puzzled by Yu Xi's strange reaction, but then she realized something and the corners of her mouth slowly turned up.

"Oh ho~ So you care about me? You care about my existence."

The Black Witch jumped off the bed and moved closer to Yu Xi.

"Speaking of which, I have heard that human boys of this age do indeed act like this. They get nervous when they are alone with a girl or when they sleep in the same room with a girl. It seems that you are the same way, Yuki. What's wrong? Are you nervous? Are you shy? Oh my, you are so cute and innocent."

“Miss Belle… if you keep going like this, I’m going to get angry.”

Yu hoped to get closer and closer to her, teasing the black witch who kept talking to her, and said expressionlessly.

"I'm angry, so what can you do about it?"
