The card player needs to win easily

(Black...under the eyes...)

(Isn't it something like "Lise of the Star Cup Fairy" or "Dream Absorber"?)

Even though she was reluctant to accept the fact that she seemed to be entangled in something, she still had to think about these things.

The more important reason was that she just discovered that the pre-assembled card deck on her panel seemed to have been tampered with.

SPYRAL Gear - Drone

"Wheel of Destruction"

DD Dynamite

There were also a lot of cards with unknown meanings - but Liva had no idea what they were.

(Can anyone else touch this panel...?)

"Naia?"

"what happened?"

Noa stopped and turned to look at Liva who called him in confusion.

"Um... do me a favor."

"Stretch out your hand, reach out to me."

"?"

Although he was confused, Noah still did it.

"Yes, here—and then move to the right."

The panel in front of me didn't change at all.

"……Thank you."

"?"

Noa walked back even more confused.

However, he didn't ask anything - perhaps he thought Liva was performing some mysterious magical ritual that he couldn't understand.

(No response...)

Liva broke out in a cold sweat.

(So, I used the panel myself? But I have no memory of it...)

(Is it because I have lost my memory?)

(No, no, it's possible that someone like "Lise the Fairy of the Star Cup" could be controlling my body using the panel... Ugh, I don't want to think about it!)

Liva, whose brain was overloaded, stopped thinking decisively.

I might as well just let Siren watch me when the time comes, or just put a pinhole camera on my body.

She couldn't come up with anything by herself.

"Turn here and go straight..."

“Hmph—hmph—”

While Noa was pointing the way, a humming sound came from somewhere.

“Hehehe—hehe—”

"What's the noise?"

Pulling Noa back, Liva stared nervously at the end of the corridor.

There are people here...but this is a place full of sea water.

But, I seem to have heard this voice somewhere before?

"……Um?"

A piece of blue cloth was revealed.

Liva instantly clenched the "destruction wheel" she had just taken out in her hand - she still remembered how "herself" in the surveillance video blew up the wall.

"Stop! Or I'll—eh?"

"what?"

The gray-haired girl swam out lightly, waving her dark blue sleeves and the silver one-handed sword in her hand.

"Hi--?"

She saw the "Wheel of Destruction" in Liva's hand.

Then, he crossed his hands in front of his chest and made a pitiful expression.

"Ugh! You're holding something so dangerous towards me...are we no longer friends?!"

"Could it be that I have been heartlessly abandoned...嘤嘤嘤!嘤嘤嘤!"

"Claw!"

Raise your hand to stop Siren's exaggerated performance.

"At this point, I think the more important thing is to rescue the others from the room... Wait, you swam here directly?"

Liva finally noticed that the Siren seemed to have no protection at all.

Moreover, he had a one-handed sword in his hand that he had seen on Celine.

"yes?"

"What's wrong?"

Pointing at the shield on his body that was glowing with a bright green light, Liva became increasingly unable to understand Siren's current situation.

"Protection! Protection! Protection like a diving suit—and where did you get this sword from?!"

Pick up "Starry Night Dragon" and show it to Siren.

Siren tilted her head.

"Well, I didn't have time to take it out for protection because of the emergency...and the sword just appeared in my hand out of nowhere."

"—Also, why can you talk underwater without any protection and without fear of suffocation?!"

Liva expressed her incomprehension for the second time.

"This."

Siren touched her pointed ears.

"I did think about this a little while ago—"

"Best answer, I don't know."

"Maybe it's because I've played Pearl Tears too much."

(Pointy ears...?)

Noa noticed some details, and then she and Mu Ma fell into the chaos of Space Cat.

“I actually think this is reasonable…”

Liva covered her forehead.

It seems that she has been assimilated into this magical world of playing cards.

"Well, the setting is like this. We just need to apply the conclusion wholeheartedly and follow our instincts. As for the principles, there are many things to consider."

"It's faster to solve problems with a formula... Stop, it's time to get down to business. Let's—find out what's going on around here."

Liva glanced at Noa, who was in shock.

"According to him, the underwater fortress is now located above sea level."

"So the seawater here must have been pumped up from somewhere."

"Hmm... let me try."

The Siren tried to turn in a circle.

The water formed several whirlpools around her.

"Feel it—ah, I feel it."

"The direction of the water flow is probably from this side..."

"This direction?!"

Looking at the direction pointed by the Siren, Noa was horrified.

"Hmm? What's wrong? Judging from the map carved on the wall and the route I just took, the source of the water is probably around here."

"This place... cough!"

Noah was so excited that he almost got a stitch in his side.

"This place is the tactical nuclear weapons storage point of the underwater fortress!"

"what!?"

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

"Kaiba, do you have any way to contact the outside world?"

Already searched the entire room.

There was no other way out—and, even though the water was pouring through the doorway, not a drop of liquid got in.

This could also be bad news.

Because, this might mean that the room is almost completely sealed -

"No, there isn't any signal from any of my devices."

"..."

Yami Yugi sighed.

"Is this all we can do?"

(Alternatively, I trust they can handle this.)

(If we can't be there in person, then let's hope.)

(Perhaps, the spirit can be transformed into a force to assist them in their progress.)

"...Yeah, partner."

Yami Yugi looked around at his companions.

"I think you're right."

"Let's pray for their actions."

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

"Hurry up! Hurry up!"

"I know!"

Noa, who was pulled by Siren and Liva, experienced for the first time what it felt like to be like the wind - although she was now in the sea.

Liva saw Noa's trembling eyes out of the corner of her eye.

“Too fast?”

"No, don't stop—if you don't hurry up you might miss it!"

Even though she gritted her teeth and struggled to resist the super-speed brought about by the two people using the card effects, Noa couldn't help feeling dizzy.

But it must be faster - that is where the most powerful weapons in the world are stored.

Even if a horrific nuclear explosion does not occur in a seawater environment, the chemical explosives used to trigger tactical nuclear weapons are enough to cause a bad chain reaction.

What's more, it's radioactive material - if it leaks here, the consequences will be unimaginable.

"Are you sure the source of the water is coming from that room?!"

"That's what my instinct tells me anyway!"
