"...Anyway, everyone, you caught me on my break."
Lust smiled.
"Come on, Sanses. How about I... show you around my house?"
The Skeleton Home.
"Oh... Looks like my brother isn't home yet..."
Lust motioned for everyone to sit on the couch, then sat down himself.
"So... everyone? What brings you here?"
This time, Killer answered him.
"We... travel through countless worlds, journeying across a sky full of stars... all to save those suffering in every world."
"...Then you probably can't help us."
Lust closed his eyes and gave a slightly sad smile.
His clothes were just as revealing and provocative as those of the monsters outside, but this was clearly just his way of fitting in.
Murder sensed that the lust within him was much weaker than in the other monsters. Clearly, he had suppressed it himself through some means.
"Well, since Papyrus isn't back yet, why not hear the story of our world?"
All three nodded.
"All right... A long time ago, the king, the queen, every one of us lived happily in the Underground."
"Then one day... the queen became pregnant. It should have been cause for the whole kingdom to celebrate."
"But..."
Lust shook his head.
"...She miscarried."
"Later, a human child fell down here."
"It unleashed its sadistic urges on us... in that particular way. You understand, right?"
"The king destroyed it. Afterward, Dr. Gaster extracted the trait from its soul."
As though they had heard a word that should never have come up here, everyone else's eyes suddenly widened.
"Wait... did you say... Gaster?!"
Killer shouted the name.
"That's right... Wait, judging by your expressions... it's as though... he doesn't exist in other timelines?"
Lust looked at everyone in some confusion, confirming his own guess.
"All right, I'll keep going. Dr. Gaster discovered this powerful trait-lust."
"At the time, the Underground also happened to be suffering from infertility... Everyone was a little worried that doing nothing would lead to our species going extinct."
"So... Dr. Gaster made the worst decision in history."
At this point, Lust took out a comb and began combing his long hair.
"He injected every adult monster with that soul trait, himself included."
"As for the results... heh... Other than the monsters' lust growing stronger... nothing else changed."
"No... Rather than saying nothing changed, I should say things got worse."
As he spoke, Lust narrowed his eyes, pink glimmering within them.
"Those... members of the Royal Guard, originally formed to seize souls... I don't even want to say what they ended up becoming..."
"Oh, and that big star. You know her too, right? MTT."
They all nodded.
"Heh, heh... She's a ghost possessing a robot. She wasn't injected with that substance, so naturally, she couldn't understand those monsters..."
"And guess what happened? She originally possessed that body because she wanted to bring education to the monsters, but instead, she was... those brutal monsters..."
Lust's fists tightened slightly. He was clearly furious now.
Furious at those monsters' brutality.
Furious at the fate that had left him here.
"...It isn't all bad. Papyrus really likes that star. He's been supporting her behind the scenes all this time... hoping she can find salvation."
Thinking of Papyrus's face, Lust's expression softened considerably. His brother was a major reason he was still in this hellhole.
If not for his brother, Lust would never have gone outside every day to deal with this sick world.
