"The cold and remote outer planets, Uranus and Neptune are known as the ice giants because their interiors are compositionally different from Jupiter and Saturn..."

The evil politician, Muzan Kibutsuji sipped a cup of cappuccino as he watched a documentary of outer planets of Solar System.

Beep! Beep!

Muzan just received a call from his secretary and right hand man, Kokushibou. He quickly answered the call.

"Good morning, Kibutsuji-sama" Kokushibou greeted his boss. "Sorry for interrupting you but we got a huge problem"

"A huge problem? What's it?" Muzan raised his eyebrows.

"Three of our spies had been murdered by the aliens, and their corpses are found by the Black Narcissus agents in an abandoned building" Kokushibou informed.

"Murdered by the aliens!?" Muzan was shocked in disbelief, he quickly raised from his seat.

"It was hard for me to believe at first, but unfortunately it's true after all" Kokushibou stated. "And more thing, our agents have been on their way to Kimetsu Town"

"Come here immediately! We'll go to Black Narcissus headquarters soon!" Muzan ordered.

"Yes, Kibutsuji-sama!"

Muzan then ended the call as he slowly sat back on his chair. His face was looking grim after Kokushibo told him the unpleasant news.

...

"Hmm...such a nice art" Natsuo smiled as he inspected a koi acryllic painting on the wall in Rengoku family's house. It was painted by Tengen himself as a flashy birthday gift for Kyoujurou last year.

"Alright, I guess it's time for us to go"

Natsuo could heard Denji's voice from nearby as the bird nest agent put his files back into the suitcase. The agents just finished gathering all informations from Senjurou and Mitsuri regarding the events of last night.

"Anyway, I must say thank you for cooperating with us, Rengoku-san" Denji thanked Shinjurou as both of them shaked hands. Denji's pet yellowfinch chirped happily.

"No problem, mister. I suggest it's better for you to buy a bird cage" Shinjurou replied awkwardly.

Meanwhile, as Shinjurou and the agents left the living room, Kyoujurou slowly rose up from the floor as he was heading to the kitchen.

"I want to take some juices from the fridge, you guys stay here first" Kyoujurou said.

Mitsuri however decided to follow Kyoujurou to the kitchen too.

"Mitsuri-chan, where do you want to go?" Senjurou asked.

"Oh, there's something important i forgot to tell your brother" Mitsuri replied.

A few seconds later, when Kyoujurou took several juice bottles from the fridge, he noticed Mitsuri entered the kitchen.

"Rengoku-sensei?" Mitsuri called her former teacher.

"Yes, Kanroji?" Kyoujurou placed the bottles on the table.

"About those aliens... I need to tell you something" Mitsuri said.

"What's it?" Kyoujurou asked.

"What do you think if they can read your mind?" Mitsuri said. "Especially when they read your past memories"

"Past memories?" Kyoujurou's expression began to change. "Why?"

...

The police officers, Kyougo and Masachika were present in the Haganezuka residence. Someone just illegally sneaked inside the backyard and badly damaged the outdoor storage shed, and they were here to investigate it.

"When I found that culprit, I'll tie him on a tree and burn them alive!" Hotaru was angry.

"Well, I think you need to calm down first" Kozo tried to calm his friend down.

"Did you found something, Kumeno?" Kyougo asked his junior.

"Not yet" Masachika replied.

Out of sudden, Masachika just found a very disturbing object inside the broken shed.

An abandoned laser gun. Did Hotaru's backyard was invaded by...an alien?

"What the..."Masachika's eyes widened. "Shinazugawa-san, can you come here?"

"Did you found anything!? Did you found anything!?" It was Hotaru who appeared behind him instead.

Hotaru's eyes widened behind his mask.

"NAAAAAANIIIIIII!?" Hotaru was shocked.

Hotaru quickly ran back towards Kozo.

"Kozo, I know you won't believe this!" Hotaru suddenly went panic.

"What's it?" Kozo started feeling uneasy.

"Masachika found an alien laser gun!" Hotaru said with a terrified expression.

"An alien laser gun!?" Kozo was shocked in disbelief. "Are you kidding me!?

"Seriously, I'm not lying!" Hotaru yelled.

"What's going on in our neighborhood!?" Kozo also went panic.

No one asked for this to happen. But what can they do now?

To be continued...

Fun Fact #6: It were Mordrezan and Bithus who damaged Hotaru's outdoor storage shed and left the laser gun in there, and the Haganezuka wasn't there during that time since he was going to neighbouring prefecture. The reason why the aliens doing this are unknown
