The Devil Does Not Need to Be Defeated

Chapter 510: “There’s No Room for a Third Person.”

Elven Homeland, Tree House.

When Shien returned with Millu, before they even entered, Carol, who had been anxiously pacing outside, silently excused herself.

Having guessed Lid’s identity, this vice-commander was undoubtedly worried about the Elven Queen and went to check on the situation.

Shien ignored her and entered the tree house with Millu, seeing the others gathered in the living room, waiting for him.

“You’re finally back?”

Lucy, sitting there, looked at Shien entering and sighed for some reason.

“Welcome back, Mr. Shien.”

Lasha’s indifferent demeanor reminded Shien of the time he didn’t come home at night, and his expression turned awkward.

“Thud!”

Lilith, without a word, immediately pounced into Shien’s arms, hugging him tightly, her face showing both relief and grievance.

“Sorry, sorry, I made you worry.”

Shien, feeling heartbroken, patted her head and comforted her.

Everyone had been waiting for Shien’s return and was finally relieved.

Only Airi didn’t have the energy to pay attention to Shien.

Because…

“Airi! Airi!”

Millu’s eyes lit up the moment she saw Airi, letting out the loudest cheer yet, then, like Lilith, pounced on her.

“It’s really you!”

Airi, seemingly having anticipated Millu’s arrival, sighed and tried to dodge, but she couldn’t avoid Millu’s pounce.

Millu hugged Airi tightly, rubbing her face against hers and cheering happily.

“Airi! Airi!”

Millu’s joyful laughter filled the tree house.

That laughter was infectious.

However, seeing this unfamiliar little girl suddenly hugging Airi, making her look displeased, everyone was still startled.

“Could this be…!?”

Lucy’s eyes widened in surprise.

“…”

Lasha also looked at Millu, silent, her eyes lowered.

“?”

Lilith tilted her head, confused.

Especially seeing Airi’s unwilling expression, yet unable to resist Millu’s hug and nuzzling, everyone’s surprise was evident.

If there were others here, they would definitely be shocked.

Airi, the Dragon Demon, one of the Six Demon Lords, known as the most ferocious being, was being hugged tightly by a little girl, seemingly displeased, yet unable to resist. This scene could definitely leave anyone stunned.

Shien, however, looked as if he had expected this.

“As expected, this girl is a Demon Lord.”

Yes.

Millu was a Demon Lord.

In other words, this seemingly innocent, naive, and romantic little girl was the sister of Airi, Sara, and Lid.

Lucy murmured in surprise,

“Millu Peshi, the Ghost Demon…”

—”Millu Peshi.”

This was Millu’s real name.

Millu was just a nickname.

The same went for Lid, who had been using a nickname. Her real name hadn’t been revealed yet.

“Airi! Airi! Airi!”

Millu hugged Airi tightly, like a beloved toy, chanting her name happily.

Airi, on the other hand, was displeased with Millu’s actions.

“Alright, stop it.” Airi said with annoyance. “Getting so excited every time you see your sister, how lonely are you?”

“Yes, yes!” Millu nodded repeatedly, looking pitiful. “Millu, lonely, Airi, always gone.”

The little girl looked aggrieved.

Unfortunately, Airi, with her heart of stone, wasn’t moved by this at all.

“Cut it out.” Airi saw through Millu’s act. “You’re always with Lid. How could you be lonely?”

Others might not know, but Airi knew very well.

Millu always had Lid by her side, never acting alone.

The reason was simple: this Ghost Demon’s mind wasn’t mature. Like a spoiled child, she rarely had her own judgment or principles.

If someone dangled a lollipop in front of her, this Ghost Demon would definitely follow them, easily deceived, and potentially causing a huge disaster.

Therefore, no one would let Millu act alone.

And Lid, if she acted alone, once she entered a battle, would become incredibly dangerous.

Therefore, these two sisters, one girl and one beast, had been together for more than ten thousand years, always acting together. One usually restrained her power, appearing weaker and under Millu’s protection for convenience, while the other acted according to Lid’s instructions, preventing them from going off track and causing trouble.

Under such circumstances, Millu always had Lid by her side and couldn’t possibly be lonely.

Of course…

“It’s different.” Millu said seriously, “Lid is older sister, Airi is younger sister.”

“What’s the difference?” Airi retorted, “They’re both accompanying you. Isn’t it the same whether it’s an older or younger sister?”

“Mmm…” Millu puffed out her cheeks and protested, “Different, different.”

“Sigh…” Airi said with a headache, “Always being difficult. Who’s the older sister, and who’s the younger sister?”

The two sisters, reunited after a long separation, started bickering.

It was quite an amusing sight, making Shien watch with interest.

“Hiss~~~”

Suddenly, a sharp pain in his waist made Shien gasp.

“You…”

Lucy had come to Shien’s side at some point, pinching the flesh on his waist angrily.

“What are you doing?”

Shien complained.

But this was met with Lucy’s glare.

“I should be the one asking, what have you been doing?” Lucy asked in a low but aggressive voice, “What did you do? Why are you with the Ghost Demon? Why is she here? What happened?”

Lucy bombarded him with questions.

Millu’s appearance had clearly made the princess anxious.

“Well, it’s a long story.”

Shien didn’t know how to explain.

Could he say that he met her by chance while bathing?

That would be ridiculous!

“Then make it short!”

Lucy didn’t let Shien off the hook.

The couple started bickering, attracting Lilith’s attention.

None of the three noticed that Millu, who was clinging to Airi, suddenly glanced at Lasha, who was standing there expressionlessly, and her innocent smile froze, her body trembling, as if stunned.

“Millu…?”

Airi noticed this, her expression turning serious, a bad feeling rising in her heart.

Millu just stared blankly at Lasha, not reacting at all.

Looking at Millu like this, Lasha, unusually, didn’t bow, but just stared at her, then reached out and patted Millu’s head.

This action not only stunned Airi, but also caused Millu’s emotions to erupt.

“Waaah…”

Millu burst into tears.

“Huh?”

“What?”

Shien and Lucy, who had been bickering, finally noticed this and looked at the crying Millu, dumbfounded.

“This…”

Even Airi was at a loss.

Lasha, however, remained unmoved, gently stroking Millu’s head, as if comforting her silently.

This development silenced the entire tree house.

Everyone looked at each other, not knowing what to do.

This scene lasted for an unknown amount of time.

Until a faint voice came,

“Alright, Millu, stop crying.”

With this voice, the fluffy and mysterious little beast appeared in the treehouse.

“Huh?”

Lilith blinked her eyes.

“Y-you… you’re…!?”

Lucy was shocked, her expression changing drastically.

“Sister Lid…”

Airi turned her gaze to Lid.

As for Lasha, she stopped what she was doing, looked at Lid, and finally knelt down.

“Lasha greets Your Highness Liddoma.”

Lasha, just like when she first met Sara and Airi, bowed respectfully to Lid.

“…Get up, don’t kneel.”

Lid looked at Lasha with a complicated expression, then said with an impassive face, a slight tremor in her voice.

“Yes.”

Lasha obeyed, like a humble maid, but her expression remained indifferent.

“Lid…”

Millu, her face streaked with tears, turned to Lid as if seeing a lifeline.

Lid sighed and turned her gaze to Shien.

“Millu and I will be staying here for a while.” Lid said to Shien, “Is that alright?”

Shien frowned, his gaze sweeping over Airi, Millu, Lid, and Lasha, then he relaxed his expression and shrugged.

“This isn’t my territory. Why are you asking me?”

In other words, do as you please, no need to tell him.

“Alright.” Lid didn’t stand on ceremony and said to Airi, “We’ll share a room. Tell me everything. What’s going on?”

“…What are you referring to?” Airi’s tone was distant.

This naturally earned her a glare from Lid.

“Of course, I’m referring to when you woke up, when you came to the human world, and why you’ve been messing around here for so long!” Lid snorted. “You better tell me everything that happened after you came to the human world!”

“Why?” Airi still protested. “I’m not Millu. I don’t need to be questioned about everything I do, do I?”

“Do you really think so?” Lid narrowed her eyes. “Do you want to have a family meeting and see?”

Airi immediately shut up.

That would definitely be a bad thing for her.

Because this so-called family meeting was a gathering of the six Demon Lord sisters to discuss matters.

If that happened, regardless of the outcome, during the process, she, as the youngest sister, would definitely be the one being picked on.

In the past family meetings, Airi had always been the one at a disadvantage.

These plastic sisters always played this trick. It was hateful.

Especially Lid, who loved using this to suppress her younger sisters.

Speaking of this, it was necessary to mention the order of the six Demon Lord sisters.

Firstly, Sara was undoubtedly the eldest sister, the firstborn.

The second eldest was the Charm Demon, second only to Sara among the six sisters, considered the second-in-command of the Demon Race.

Then there was Lid, the third eldest, with three younger sisters.

The Poison Demon was the fourth.

Millu, the Ghost Demon, was the fifth.

And finally, there was Airi, the youngest, the baby of the six sisters.

And as everyone knew, the youngest sister had no rights. Airi always felt that she was being persecuted by her five older sisters.

Which older sisters would take turns using their younger sister as a body pillow, refusing to sleep without hugging her?

Which older sisters would force their younger sister to bathe with them and always touch her inappropriately?

Which older sisters would treat their younger sister like a doll, always wanting to play dress-up?

Which older sisters would interrogate their younger sister about everything she did, treating her like a pet, always keeping her at home?

Airi had them!

And she had five of them!

Even Millu was persecuting her!

Therefore, Airi had become a bit rebellious, not wanting to listen to her sisters at all.

However, if Shien knew about this, he would definitely say without hesitation,

“Is this persecution? This is clearly the doting of a group of siscons!”

This was the truth.

However, Airi would never think this way.

Therefore, Airi could only resist.

“I don’t want to share a room with you.”

The youngest sister, rebelling online.

“Oh?” Lid seemed used to this and said nonchalantly, “Give me a reason.”

Airi really wanted to say that there was no reason, she just didn’t want to.

But she also knew that if she said that, she would be seen as a spoiled child and be ruthlessly suppressed.

Lid knew very well that Airi hated being treated like a child.

Under such circumstances, as long as Airi didn’t give a reasonable excuse, she would definitely be provoked by Lid and forced to accept sharing a room.

Knowing this routine, Airi racked her brains.

After a while, Airi seemed to have an idea and turned her gaze to Shien.

“…”

Sensing Airi’s gaze, Shien’s lips twitched.

A sense of foreboding, a premonition of impending doom, suddenly arose in his heart.

And the next moment, Airi’s words confirmed his premonition.

“I’ll stay with that man.”

Airi pointed at Shien and said loudly,

“We always share a room. There’s no room for a third person.”

The air instantly froze.

Shien felt his vision darken, a single word appearing in his mind.

That word was—”Danger.”
