Serenia came again to the Kimetsu Public Park as usual. But for this time, she wasn't alone, Tiresias was also there with her. It's not that she needs someone to accompany her, but Tiresias only wanted to tag along too.
"So... you're an alien, Serenia?" Mitsuri asked for confirmation.
Serenia took a deep breath before finally spoke.
"Yes, I'm" Serenia slowly nodded. "But you must trust me, I didn't come here to harm anyone or bring any ill intention"
"Seriously!? You are a human from another planet!?" Inosuke was excited to meet Tiresias.
"Yes?" Tiresias smiled awkwardly.
"Does your people cook tempuras in their hometowns?" Inosuke asked.
"Tempura? What's that? Is that some kind of food?" Tiresias was confused.
"You don't know what's a tempura!?" Inosuke was shocked.
"No, I didn't" Tiresias shooked his head.
"Inosuke..." Aoi sighed with a frown.
"Serenia, there's something I must tell you!" Mitsuri said.
"What's it?" Serenia was curious.
Serenia soon noticed Senjurou was standing behind Mitsuri.
...
Professor Demaclos only wants to continue his great-grandfather's legacy. He don't really care if his ambitions was against the decisions of Supreme Council, but he was more than willing to achieve it. he expected absolute respect from everyone, and wished to eliminate those who oppose him, even for those who hid in the shadows.
Somewhere in an unknown location, Demaclos stared silently at a huge transparent blue sphere in the centre of a dark hall. Inside the sphere, there's a bald humanoid with pale white skin and claws floated unconsciously. His latest project was almost completed, and now he only waited for the right time to unleash the full power of his new masterpiece.
Soon, he was approached by a white robot shaped like a skeleton with a pair of light blue eyes from behind.
"My Lord" the the robot addressed his superior.
"What?" Demaclos slowly turned his face, raised his eyebrows.
"They're coming, My Lord" the robot informed.
"Just let them be, I'll give them a very nice surprise they won't forget soon" Demaclos replied.
The robot then left the hall.
"Grrrrrrrrrrrrr..."
Another creature just showed up behind Demaclos. It's The Night Crawler, and it survived the fight against The Birdman.
"There you're, Revidox" Demaclos smirked at his servant.
...
"The evil aliens you met in the last night..."
Serenia turned her face towards Tanjirou and friends with a grimful expression.
"Are the minions of Zargoror" Serenia said.
"Hahahahahaha!" Susamaru laughed as she ran behind the alien girl, carried a volleyball.
"Zargoror?" the rest of them were dumbfounded.
"So who's this Zargoror anyway?" Tanjirou asked.
"Many years ago, Zargoror was a high ranking officer in the military, and his reputation is well known across my home planet. My father and my captain are serving under him as his subordinates. However, Zargoror betrayed our own kind in a war when he switched his allegiance to our main enemy, the Gorgoronian Empire" Serenia explained. "Our forces finally defeated the Gorgoronians in a devastating battle, yet he somehow survived and formed his own pirate crew after the war ended. And now, he's coming to Earth to search for an ancient weapon hidden beneath the southernmost continent of this planet"
"WOW! There's a powerful weapon hidden in the land of penguins!?" Inosuke was shocked in amazement.
"Why are you so excited!? They're going to kill us, you dummy!" Zenitsu yelled.
"Hahahaha! You're so weak, Monitsu!" Inosuke laughed.
"SHUT UP! I'M NOT WEAK!" Zenitsu yelled louder than before.
"Does she mean Antarctica?" Senjurou glanced at Tanjirou.
"Yes" Tanjirou nodded.
"What are he going to do with that weapon?" Mitsuri asked.
"Honestly, I don't have any information about his real motives, but this can't be a good thing" Serenia stated.
"I'm just worried if they're coming again to our neighborhood tonight" Mitsuri's face showed worried expression.
"Alright, don't worry, I'll inform my father and my captain about this" Serenia assured.
"And looks like I need to lend my brain and hands too" Tiresias said.
"RUN!"
Out of sudden, all of them were clueless as they could heard people screaming from nearby.
"Hey, what's happening!?" Zenitsu was panic.
A few seconds later, they were shocked when a hot air balloon crashed against the tree. Luckily the passenger survived the crash.
"What the!?" Tanjirou was shocked.
"I'm okay!" the passenger shouted.
...
In the sewers beneath Kimetsu Town, two unnamed robbers were trying to find their way to the museum. They couldn't risk themselves by getting chased by the cops.
"Alright! Now we need to keep our eyes open and stay alert!" Robber 1 said. "We'll be lucky if we're able to find a shortcut to the museum!"
"But the problem is we're supposed to go to the museum, not the sewers!" Robber 2 stated.
"Can you shut your mouth please!? At least we're safe from the cops!" Robber 1 scolded.
"But this place is very creepy" Robber 2 commented.
Out of sudden, the robbers just heard an inhuman scream from nearby.
"What's that!?" Robber 2 was scared. "Can we get out from here now!?"
"I don't if care if there are any monsters hiding in there! They won't stop us from-"
A strange creature just appeared in front of them. It was a huge frog-like creature with purple skin, clawed legs and a pair of antennas.
"What the heck is that?" Robber 1's eyes widened.
"A...frog?" Robber 2 was confused.
"Rrrraaaaaaaagggghhhh!" the frog-like creature screamed again.
