In the same location where Captain Eurydox met the Superiors, the leader of a gang was shoved on the ground, heavily injured as his henchmen were laying unconsciously, scattered around him. Stood in front of him were a trio of powerful Half-Infesters (any person who consumed the blood of an Infester) who addressed themselves as the "Fallen Angels"; Schwarzengel, Segador and Pegaso.

"Damn you..." the gang leader muttered in pain. "Why are you doing this to me?"

"Blame yourself first before you blame the others. You're the one who broke the promise" Schwarzengel reminded.

"You're the one who tricked me to do your silly biddings! I'm grown tired from all of this!" the gang leader was furious.

"Tricking you?" Schwarzengel chuckled. "I never tricked anyone"

"YOU'RE DEVIL!" the gang leader yelled.

Schwarzengel violently stomped his leg on his stomach, making the gang leader shrieked in pain.

"Be grateful that I saved you from the blasted Slayers because you're going to suffer in Hell if I don't" Schwarzengel stated.

Schwarzengel pulled out a laser gun before aimed it against the gang leader.

"Now I give you one last chance...' Schwarzengel said. "Listen to me or say goodbye to this world"

The gang leader was mentally at the crossroads, wether he'll continue to obey him or lose his own life.

...

"What's the meaning of this?"

In a lounge room inside the headquarters of Kibutsuji Foundation, Muzan stood in front of his underlings with a very upset expression.

"Why can't even every of you create a single scratch on that masked brat!?" Muzan banged his fist against the wooden table.

"Muzan-sama, we've tried our best but-" Douma interrupted.

"SHUT UP!" Muzan silenced him. "I don't have time to listen to your excuse!"

"Oh no, Muzan-sama is really angry right now! What should we do? I don't want to get fired!" Hantengu covered his face with his hands in fear. Kaigaku only sighed with a frown.

"If I met that fool again, I'll personally cut him to pieces and fed his remains to the crocodiles!" Muzan growled.

Muzan then turned his face towards a male person with a black fedora hat who stood next to him.

"Kharkhor"

"Yes, Boss"

Kharkhor, the secretary of Kibutsuji Foundation. He's a were serpent who formerly began his career as a talented magician.

"I want you to find more information about that brat" Muzan ordered. "Got it?"

"Yes, boss" Kharkhor nodded.

"From this moment, I want everyone know that no one shall mess with me, or they'll face the dire consequences!" Muzan warned.

Deep inside his heart, Muzan felt an immense level of anger. He hates it when someone messed up with him.

...

"Can someone please tell me how to get out from here? This place is much more worse than the most dirty place I ever seen!" Mordrezan blabbered.

"BURN THIS PLACE!" Orbaum shouted.

Soon, Mordrezan spotted a prison janitor passed through the hallway.

"Hey you!"

The prison janitor noticed Mordrezan was calling him.

"Yes?" the prison janitor raised his eyebrows.

"Let me out from here right now!" Mordrezan ordered.

The prison janitor only stared silently at Mordrezan.

"Will you give me Rs 5 lakh crore if I have the key?" the prison janitor said.

"Why I must give my own money to you?" Mordrezan replied.

The prison janitor however ignored the alien as he then walked away from there.

"Come back here, you dork! I'll cut your weak legs for that!" Mordrezan was angry.

"CUT HIS LEGS!" Orbaum shouted again.

"Can you please shut up for one second!?" Vozurek scolded.

...

Goriun and Vodnek focused their eyes on a large screen inside their spaceship. Eight red dots were seen blinking on the map, indicating the locations of the Demon King and the Upper Ranks.

"They're hiding not far from us, but we need to wait for the nighttime to lure them out" Vodnek said.

"But their main weakness grows the impatience inside me, my liege. Better we act now instead of waiting for nothing" Goriun said.

"Be patient, General. We must not be too hasty in our plans" Vodnek replied. "Even only a little mistake can lead to loss of our chance"

"What about those pesky Slayers? I know they won't sit quietly if they noticed our presence" Goriun stated.

"Forget about them, they're not our focus for now" Vodnek replied again.

Meanwhile in the other side of the spaceship, as one of huge-sized automated doors was opened, a swarm of winged humanoid Infesters with dark green skin and blackish red eyes swiftly flew outside, followed by another swarm of huge-sized carnivorous worm Infesters with insect-like wings and sharp teeth. Their inhuman screeches echoed in terror and fury as they flew away from the spaceship.
