The card player needs to win easily

Then, a mermaid girl dressed in the same style as Siren and Celine appeared.

(Isn’t this really a Pokémon?!)

"Mello!?"

Celine braked abruptly.

She looked at the girl in front of her holding a long-handled hammer in surprise and doubt.

But, after only a moment's pause, Celine gripped the one-handed sword tightly and rushed forward again with an indomitable momentum.

“Renohart—!”

(It seems to have made her misunderstanding even worse!)

Siren looked at the duel disk that had been giving prompts and confirmed it decisively.

"I activate the effect of "Melo Mermaid, the Tearful Lament Tribe"! Send the top three cards of my deck to the Graveyard!"

The same azure light covered the Merlot Mermaid of the Pearl Tear Lament Tribe.

As she swung the long-handled hammer in her hand, the power was transferred to the top of Siren's deck.

"The Pearl Tears Lamentation Clan Type Kushagha Wrathful Clan"

"Revolutionary Synchronicist"

Gray Flowing Beauty

"Activate the effect of 'Pearl Tear Lament Tribe Type Kusha Rage Tribe'—Ugh!"

Siren deftly dodged the hammer-wielding Merlot Mermaid of the Pearl Tear Lament Tribe and stabbed Siren's abdomen with a single sword.

(Is that a bit forced...?)

Siren looked at the one-handed sword that pierced her body.

Logically speaking, if this sword strikes, at the very least, I will lose the ability to move - permanently.

However, not a drop of blood fell from the wound.

"Life force is really tenacious—"

The "Melo Mermaid of the Pearl Tear Lament Tribe" behind her had already caught up with Celine, and she had no choice but to draw her sword to block the long hammer.

"…Is everything alright?"

There was some pain, but not as much as Siren had imagined.

Instead, a feeling of weakness swept over my whole body.

The corner of his eye inadvertently glanced at the top of his duel disk.

LP: 8000-5700

"All damage received becomes loss of basic points..."

(That's what "Dark Game Mode Type 2" means... Then, I need to use my deck to defeat "Tear Crown Elegy: Celine" before my basic points reach zero!)

"Using the effect of 'Kusha's Wrathful Tribe', I send two cards from the top of my deck to the Graveyard!"

Beneath the calm surface of the sea, some scarlet creature roamed at the bottom.

(You have to have something usable!)

It was obvious that the "Melo Mermaid of the Pearly Tear Elegy Tribe" could not hold out for much longer.

Such a will arose from the Siren's heart.

The blue light flashed again.

"The sound of claws rubbing against each other in this life"

"The Lament of a Bad Life"

After defeating the "Melo Mermaid of the Pearl Tear Lament Tribe" that was no match for her, Celine saw the two cards floating out of the water.

To be precise, it is "the lament of a bad life."

"Qi...duo?"

"Chain one, 'The mournful song of a lifetime of evil', chain two, 'The rubbing claw sounds of a lifetime of evil'!"

"Return "Pearl Tear Lament Tribe - Kusaka Rage" from the Graveyard to your hand, and add "Pearl Tear Lament Tribe - Siren Mermaid" from your Deck to your hand!"

The one-handed sword stabbed at the Siren again.

However, this time, the creature that was originally active on the seabed caused a huge wave when Siren was about to cut Siren's heart with her sharp blade.

"!"

With her vision obscured, Celine had to give up the attack.

In front of her, the creature slowly materialized.

Mermaid?

No, this wasn't some merman—not even a living thing.

A body made of scarlet mechanical structure, a giant axe replacing the right arm, and long hair that is almost pale.

"I activate the effect of 'Pearl Tear Lament-Tribe, Kusha's Wrathful Tribe' to banish 'The Claw of a Lifetime of Ruin'' from the Graveyard and Special Summon this card from my hand!"

The red mermaid raised her axe high.

Just as Celine was about to dodge and rush towards Siren, past the imitation, the power of "Wrath" was revealed.

"I activate the effect of [Pearl Tear Lament-Tribe-type Kusaka Rage-Tribe]! Send the top three cards of my deck to the Graveyard!"

An axe struck the originally calm sea surface, splashing water everywhere.

Three cards floated up in front of the Siren.

"Pearl Tear Singing Tribe - Renohart"

"The Demon King of the Swamp"

Tuning

Looking at the "Pearl Tears Lament Clan-type Kusaka Nuwei Clan" that exuded an ominous aura, Sailian began to doubt for the first time.

(Renohart... can actually control something like this?)

(No——even escaping like this can happen, so it’s not impossible for him to gain new abilities.)

With a firm will, he gripped the one-handed sword again.

The speed increased again.

He dodged the axe by leaning forward, and while he was changing his posture, Selene used her sword to cut the right arm of the "Pearl Tears Lamentation Clan Type Kusaka Nuwei Clan".

"Activate the effect of "Renoheart of the Pearly Tearful Lament"! Special Summon this card in Defense Position and discard "The Little Mermaid of the Pearly Tearful Lament"!"

The machine, having lost its giant axe, naturally had no power to resist.

The moment Sylvan cut off its head, the impact was felt by Siren.

LP: 5700-5200

(Converted... her attack power increased from 2300 to 2800.)

If Selene possesses such a method to continuously improve her combat capabilities, then she must act quickly.

(Someone...someone!)

Someone appeared in front of Celine.

He was covered in light armor and held a whip blade.

A person who once used the power of "sorrow" to enslave and bring countless nightmares.

"Pearl Tear Singing Tribe - Renohart"

"...!!!!"

Her eyes widened.

Almost instinctively, Celine swung the most resolute sword strike she had made in the entire battle.

"—Chain 1, activate the effect of "Pearl Tear Lament Tribe: Renoheart" and send a "Pearl Tear Lament Tribe" monster from your deck to the Graveyard!"

"Chain two, activate the effect of [Pearl Tear Elegy Tribe - Little Mermaid] and perform a fusion!"

The blue-haired man was hit through the heart, and the aftermath swept across the Siren in the distance.

LP: 5200-4200

With one blow from Selene's sword, "Renohart of the Pearly Tear Singing Tribe" was easily killed.

A green swamp suddenly appeared around.

Under the chaotic and sticky shaping, the man stood up again.

"What--"

"...I use "Demon King of the Swamp" instead of "Renoheart of the Pearl Tear Lament Tribe" and return "Little Mermaid of the Pearl Tear Lament Tribe" and "Melo Mermaid of the Pearl Tear Lament Tribe" to the Deck for a Fusion Summon!"

The Siren, who was blown far away by the aftermath, resurfaced, stood wetly on the sea, and declared fusion.

"Kaledohart of the Pearl Tear Singing Tribe!"

The man gradually sank into the sea.

When it reappeared, the "Melo Mermaid of the Pearly Tear Lament Tribe" and the "Little Mermaid of the Pearly Tear Lament Tribe" were tied below its mutated legs and were lifted up mercilessly.

Renoheart's final form - draws upon everything in this world to gain power.

"Activating the effect of 'Pearl Tear Singer's Clan, Kaledohart'... Tsk, it can't be activated."

When the effect was about to be activated, Siren realized that it seemed that in this battle, Celine had been acting as her own thug.

In other words, the opponent seems to be a "Dueler" or something like that, and cannot be treated as a card on the field.

A tentacle shot out and hit Celine's body.

"[Pearl Tear Singer Clan, Kaledohart], launch a direct attack!"

He barely managed to block several whipping blows with his sword, but was accidentally hit by the whip blade held by the evil-smiling man and rolled out.

"Now that I'm out of control... how can I fall down in this place?!"

Blue light excitation.

He mobilized all his strength to fight against the tyrant creature in front of him, a creature he had never seen before but was extremely familiar with.

"drink--"

There is only one way to get rid of the monster in front of us.

One hit kill.

I have to break some limits——

Selene wielded her one-handed sword and cleared a path to avoid all the tentacles blocking her way.

The whip blade swept across.

However, Selene, who had already entered a certain state of perfection, simply blocked lightly, completely deflecting those attacks.

In a flash, she came in front of Renohart, whose face was becoming increasingly terrified.

"Go to hell."

The gem-like structure on the chest of "Kaledohart of the Pearl Tear Lament" shattered with a sound.

The one-handed sword pierced his chest.

"Well--!"

The tentacles lost their vitality, peeled off from the man's body, and fell to the bottom of the deep sea.

"Kaleidohart of the Pearl Tear Lament Tribe" spat out a blue, turbid liquid with a look of shock.

Immediately afterwards, the energy released by the broken gem on the chest completely dissipated.

"boom!"

The man who had transformed back into "Renohart of the Pearly Tear Elegy Tribe" collapsed onto the sea, his eyes gradually losing focus.
