Even if you're a corrupted magical girl, you still have to try to redeem yourself.

Tentacles surged wildly into the sanctuary through its cracks, exploring its unknown areas and trying to tear it apart.

If this terrifying beast were replaced with a human, this scene would absolutely never be shown! Absolutely!

Although its cries were just as agonizing, making the girls' eardrums ache.

The creature beneath Nishio Reki's feet opened its terrifying jaws and bit down on the beast's head, forcefully tearing off the black, sticky substance. It spat the torn-off black mud into the water and then plunged its teeth back into the head.

The beast's recovery speed was clearly not keeping up with Nishio Reki's tearing, but it was still standing firm and had not fallen.

Helica wasn't sure if her current attack would be effective, but seeing how pitifully it was screaming, it seemed inappropriate not to give it a few more hits.

"Again! Keep going! Three! Four! Five! Six! Ora Ora Ora Ora!"

Herlica roared, pounding on Yuuki with the same force and power she used when she brutally beat him in the dream.

At this moment, the fists changed their attack pattern. The lightning that burst forth was no longer concentrated on one point, but became an area attack that covered the entire back armor. The current formed a huge net of light through the sea surface, further adding wounds to the sanctuary.

"Not enough, not enough, not enough! Useless, useless, useless, useless! Take this punch!"

Helica became even more excited. Now she screamed like a blonde villain in a Stand fighting manga, raising her fists high. The giant lightning fist in the air also clasped together with its fingers, and fell down with Helica's arms.

Cracking sounds filled the air, and the entire body of water was dyed silvery-white by the flowing lightning, as if a flashbang had been dropped, blinding the girls.

This was the limit of what Helica could do; she was quite confident in her offensive capabilities.

If this doesn't cause any damage, Helica will really be disappointed.

"Phew! How was that!" Helica took a few steps back, looking around, waiting for her companions' response.

"Not very good!"

As Helica's vision gradually cleared, Nishio Reki appeared with several scorch marks on his face, and his once smooth black hair was now sticking up like a black sea urchin from the electric shock, making him look as miserable as could be.

Giant beasts don't electrocute people, so there's only one possibility for how Nishio Reki became like this.

"Helika, are you sick? I told you to attack, not to shock me too!" Nishio Reki, as if possessed by Baki, pointed his halberd at Helika's nose and started cursing.

"I didn't mean to shock you..." Helica said a little guiltyly, fiddling with her fingers. Her two giant fists, which were being controlled by her, also moved in mid-air to strike her fingers.

Helica got a little too excited while fighting. In Moonsea City, she had to be careful that her strength wasn't too great and might affect the surrounding environment. But this was the Dreamland, and her opponent was an unusually resilient turtle. For a moment, Helica really forgot to hold back.

No, it's not that Helica forgot to hold back her power, it's that Helica couldn't hold back her power, and she couldn't hold back her power against an opponent like that either.

"Besides, besides, I didn't electrocute Yumehara Sumireko, look, she's fine..." Helica quickly argued, turning back to look at Yumehara Sumireko behind her, who was manipulating the water flow and the octopus.

As expected, Sumireko Yumehara was unharmed; since she hadn't rushed in directly, she wouldn't have been affected.

However, Sumireko Yumehara's expression was a little strange at the moment. She was staring intently at something, her lips twitching constantly, as if she had seen something incredibly astonishing.

Herlica followed Sumireko Yumehara's gaze and saw the giant octopus controlling the enormous sanctuary coiled up, its body several shades redder than before, emitting a unique and fresh caramelized aroma, and the pupils of its enormous eyes completely transformed into X shapes.

"Is it... cooked?"

Helica, like Sumireko Yumehara, twitched the corners of her mouth.

As if responding to Helica's words, the giant octopus slid down its legs around the hoof of the Sanctuary Beast, its body curling up like a small, roasted octopus. The sea monster's enormous body plunged into the dark blue water below with a splash, the spray almost hitting Helica's face.

The giant octopus floated on the water for a while, then began to decompose, turning into a ball of blue magic that dissipated into the air.

"Uh...it's because, because water can conduct electricity, oh yes, that's right, that's it, Yumehara Sumireko made a little, a little too much water..." Herica's expression completely broke down.

"I don't want to hear this little bit of science! I don't want to hear it! If you have that magic, go ahead and shock it! Don't shock me!" Nishio Reki grabbed his messy hair a few times to make himself look less disheveled, and shouted in despair.

Even the giant octopus was electrocuted; if Nishio Reki were a little weaker, he might not be standing here unharmed.

Well, "intact" here means it hasn't turned into a charred mess and is beyond repair.

"However, our attack was effective."

Sumireko Yumehara interjected appropriately, trying to smooth things over between the two, and casually pointed her trident at the enormous beast churning with heat.

Nishio Reki and Tenrai Herika looked together at the ferocious beast lying on the ground, its body emitting smoke.

The beast's entire body was covered in black mud, marked with burn marks. Its massive hooves and the joints between the stone bricks were riddled with holes from lightning strikes. A nauseating, pungent odor emanated from its horrific wounds, making the smell of the freshly grilled octopus even more bizarre.

The monster was drooping its head, trying to get up from the ground, but its injuries were too severe. Its hooves, which had just landed, could not support its weight and it bent to the side at a painful angle.

The flowing black mud was still repairing the giant beast's wounds. Its bent hoof kicked a few times before it stood firmly on its feet. It was believed that the Sanctuary Monster would soon be back to normal.

"It worked, but only temporarily." Nishio Reki had tidied his hair and looked serious. "Compared to its self-repair speed, our attack is still not strong enough."

While it's certainly cause for celebration that the attack was successful, the monster's powerful regenerative abilities meant that the attack would soon become futile again.

“But it’s not all bad. At least we’ve discovered what this strange thing’s weakness is,” Sumireko Yumehara said.

It's clearly illogical that the combined attacks of three magical girls couldn't break through its defenses.

During the attack just now, they suddenly realized that the answer had always been on the surface of the mystery.

The black mud covering the monster's surface, forming its head, hooves, and connecting muscles, is its true weakness. Just like the Arces, if Umki attacks it, the monster will definitely lose all ability to move.

The girls exchanged glances and understood what Sumireko Yumehara meant.

However, Achilles' heel is just a foot; this monster is more like a giant tortoise, a multi-legged giant tortoise, and it's not easy to cover all the soft flesh inside.

Nishio Reki scanned the beast's entire body. By now, most of its injuries had healed. Its body, which was entirely made of black mud, had no specific tissues. All it needed to do was fill it with mud, but this was the most troublesome thing for the girls.

“Heracles of the Heavenly Thunder.” Nishio Reki turned to look at Heracles: “As long as our attacks are strong enough to outpace its regeneration, that’s enough. So, can your attacks be even stronger?”

“No, my output efficiency is also limited.” Helica shook her head.

A magical girl's body is like a swimming pool; no matter what she does, there's a limit to how fast she can release water. This doesn't conflict with the fact that everyone usually releases water slowly to save magic power.

"Damn it, this is troublesome." Nishio Ryū dejectedly touched his burnt hair again.

"Oh well, why worry about it! Now that we've found a weakness, let's just hit it hard, shall we?" Helica clapped her hands, raised her fist, and looked ready to charge forward again.

When faced with a problem, she tackles it without hesitation, which is very much in Helica's style.

But this battle is especially crucial, and Helica is a key fighting force; she cannot allow Helica to squander her magic.

"It's easy to say, but how are you going to attack so many places at the same time? Even Inuyama Tomoe's explosions couldn't cover them all."

“What did you say?” Helica interrupted Nishio Reki.

"I'm asking you, how are you going to attack so many places at the same time?"

"No! The next line!"

"The next sentence is, even Inuyama Hideki's explosion could not completely cover it."

"That's it!" Helica exclaimed, slamming her fist into her hand. "This is it!"

"Huh? What?" Nishio Reki was startled by Helica's sudden excitement.

"As long as I can cause a big enough explosion, wouldn't that be great?" Helica had a sudden realization and bumped her fists together. "You two are both water-type! Right?"

"Yes, that's right."

"Yes."

"Then give me a good bath! Let this guy give me a proper shower! If one person's magic isn't enough, then three of us will do it together!" Helica rubbed her fists, full of confidence.

"Why?" Sumireko Yumehara asked, puzzled, but she still raised the trident without rushing to do anything.

"Why worry about all that! Just do it!" Helica urged.

"Because water can conduct electricity?" Nishio Reki put his newfound knowledge to use.

"I told you not to worry about it so much!" Helica continued to urge.

Although there isn't such a rule in magical girls, everyone who fought alongside Yuuki Yuuki lived up to it.

Trust your companions.

Sumireko Yumehara and Reki Nishio raised their wands together, and streams of black and blue water rose from the dark ocean, converging in the air before falling back to the ground.

The water pounded against the Holy Beast, which had mostly recovered. The mud on the beast's body was washed away, but it seemed to come alive and began to writhe, like slimes clinging tightly to the beast's body, swaying repeatedly in the water.

"No! It won't wash away!" Nishio Reki shouted, raising his voice amidst the rushing water.

"It's alright! I wasn't planning on letting you wash it off anyway! Keep going!" Helica said, as crackling electricity, like tiny silver snakes, began to emanate from the air around her, clearly indicating that she was gathering some even more powerful attack.

"How far should we continue?" Sumireko Yumehara continued to brandish her trident.

"Flood it!"

The water flowed around the strange beast like a swimming fish, gathering more and more around the sanctuary. Suddenly, the iridescent spherical water film expanded, enveloping the entire sanctuary in a semi-transparent cage.

A colossal black dragon coiled atop the bubble, dark liquid continuously seeping from between its claws, increasing the density of the water's interior. A gigantic octopus made entirely of water reappeared from the water below, its tentacles rapidly multiplying within the confined space. The fluorescent patterns on its tentacles resonated with the water, relentlessly slapping at the restless beast and halting its struggles.

Having already suffered a combined attack from the girls, the behemoth became even more ferocious, constantly ramming its massive body against the edge of the giant bubble even while it was inside it.

The bubble that rose into the air and enveloped the giant beast trembled violently, with ripples spreading out from its edges. The ripples piled up and caused towering waves to rise from the bubble.

"How much longer!" Nishio Reki gritted his teeth, while the giant dragon coiled on the bubble waved its massive claws, calming the turbulent waves in its own unique way.

"Wait a little longer!"

"It's moving too much. I'm fine with just outputting magic, but I can't maintain this form for long," Sumireko Yumehara coldly reminded her, her face already soaked with sweat as she moved away from the center of the conflict.

"I said! Wait a little longer!" The surge of magic tousled Helica's golden hair, but in Helica's hands, she seemed to be holding something new.

The colossal beast that the sanctuary had transformed from raised its head and let out a silent scream from within the bubbles, an unprecedented destructive force spreading out from the beast's center.

The surging magic collided with the surrounding bubbles, causing them to burst in the air like balloons, and the magic that made up the bubbles scattered and fled.

The water droplets that splashed into the air suddenly stopped, as if everything had remained frozen at the moment of the explosion.

Nishio Reki and Yumehara Sumireko gripped their wands tightly, their teeth sinking deep into their lips, but the pain from their clenched teeth seemed to have no effect on the girls; at that moment, they had only one thought in mind.

Buy some time!

The stagnant water droplets scattered in the air retreated rapidly as if time had reversed, each drop striking the beast that had burst through the bubbles and was roaring with its hooves raised.

Tiny droplets of water began to converge, accumulating again on the beast's body and enveloping it once more.

The aimless beast seemed to panic, trying to break free of its cage once again.

However, it no longer has that opportunity.

"Helika!"

"They're here!" Herika shouted, raising her hands as if tearing open the sky above the monster's head.

Countless silvery-white currents, like veins, burst forth from the depths of the torn sky, continuously connecting and reconstructing behind the muscular, lightning-like fists, finally forming a towering, earth-shattering figure of lightning.

"Big," was Nishio Reki's first impression.
