Demon King – Chapter 377 – I Am Your Little Sister!

“Sleep. Be good. Stop making trouble…”

Coaxing a certain silver-haired girl who kept complaining about headache and discomfort, Yuki’s face was filled with helplessness.

“Can’t sleep. I can’t sleep. I’m going to die…”

Sitting on the bed, Her Majesty the Demon Lord pressed both hands against her temples, trying to ease the headache this way, but the effect was obviously minimal.

“If you can’t sleep then lie down for me. Stop climbing up and making trouble. Learn from your little sister.”

Pointing at the girl lying on her sister’s thighs, Yuki scolded her without mercy.

“Wuu…”

Eiya, who was lying on Eiru’s legs, let out a timely groan of discomfort, clearly much more well-behaved than her sister who was trying to get up and party.

“Close your eyes and rest. Do you understand?”

Yuki scratched his head in frustration.

“I know you’re lively and active, but please take that usual slacking spirit of yours and lie properly on the bed right now!”

“Stupid Yuki, the so-called slacking isn’t just being lazy and not moving. The meaning of slacking is…”

“I’m not arguing with you about that right now. If you don’t sleep, I’ll find a way to make you sleep!”

As he spoke, Yuki crooked his fingers at his little girlfriend twice. That subtle gesture instantly made a certain girl break out in goosebumps.

“You wouldn’t be thinking…?”

Her Majesty the Demon Lord’s tone carried some uncertainty, even though she had already more or less guessed what he was thinking.

“Anyway you have succubus blood. You’re quite willing to do that kind of thing, right?”

“But Little Ya is still here. I think that’s not very appro—”

Trying to use her little sister as a shield, Her Majesty the Demon Lord was cut off halfway through by the girl lying on her legs.

“I can leave for a moment…”

After saying that, Eiya climbed up, wobbling as she prepared to walk toward the bedroom door.

“No, Little Ya! If you leave, I’m done for!”

Eiru panicked and hugged Eiya tightly.

“I’m your dearest big brother. You absolutely won’t be this heartless, right!”

But both sisters were in terrible condition. Their whole bodies were weak, plus dizziness and headaches. With Eiru making such a violent movement, the two girls lost control and flopped down onto the bed with a smack.

““Wuah!””

The two sisters let out pained sounds in unison. Dizzy, head hurting, and then taking a fall like that. Even if it was on a bed, it was still more than enough to make them miserable.

Seeing how uncomfortable the two girls looked, Yuki was racking his brain over how to coax them to sleep. Unable to stand the situation any longer, Eiya suddenly spoke to him.

“Brother Yuki, there’s a small box in my bag. Take it out…”

“A small box?”

Even though Yuki was full of question marks, he still followed what Eiya said and found a delicate little box in her bag.

“Open it. Then bring it in front of us and crush it.”

“Oh…”

Responding, Yuki opened it and found that inside were exquisitely made light purple little round balls.

“Wait, what is that?”

Feeling something was wrong, Eiru was just about to make a run for it when she realized her little sister was tightly holding onto her.

“I can’t take it anymore, so let’s die together, sister…”

Eiya made a dangerous and confusing statement, and after a wave of fragrance spread, the two girls lost consciousness just like that.

‘Damn it, lavender again. Why did Little Ya go down together with me too? Shouldn’t you be immune to this…’

That was the last thought in Eiru’s mind before blacking out.

“Cough, cough, cough…”

The room was filled with the scent of lavender, so strong that even Yuki found it hard to endure. The smell made it hard for him to breathe.

“Isn’t this way too strong? Is this meant to choke people to death?”

While complaining, Yuki noticed that the two girls on the bed had already lost consciousness. They were sleeping very peacefully.

“Wahahaha! I’m really a genius. I actually pulled the mutual destruction move! Hahahahaha!”

At the boundary between dream and reality, Miss ‘Insurance Mechanism’ rolled around clutching her stomach with laughter when she saw this scene.

“But I’m affected by lavender now? That means… the transformation is almost complete? The day I go back isn’t far off?”

Catching the key point, a hint of excitement appeared on Miss Insurance Mechanism’s face.

“Ah, being locked up here for so long was suffocating. And I had to constantly eat dog food… How should I tease and bully big sister after I get out?”

Miss Insurance Mechanism wore a mischievous grin, completely unaware that a silver-haired girl with a blank expression was standing behind her.

“What are you talking about?”

“Wha! You, you, you! When did you get here?”

The sudden voice from behind scared Miss Insurance Mechanism badly.

“From the line ‘the day I go back isn’t far off’… So what are you talking about? Were you locked here by me?”

Her Majesty the Demon Lord found it hard to accept. She couldn’t believe that her past self would imprison someone.

“No no, semi-voluntary… No wait, what am I even saying? Anyway you don’t need to dig into it. You just need to know that I… wait, what are you doing?”

Her thoughts in a mess, by the time she came back to her senses, she realized Eiru was reaching out to fiddle with the wings behind her.

“These wings… fake?”

Looking at the wing fragments in her hand in disbelief, and seeing that the other party showed no sign of pain, Eiru reached that conclusion.

With a light snap, a gap appeared. Starting from the cracked spot, as if unable to maintain their existence, the other party’s wings turned half-transparent.

“W-W-W-W-What are you doing! Do you know how much effort I put into making these wings exactly the same as yours! They’re really hard to make!”

Panicking as she tried to protect her wings, Miss Insurance Mechanism attempted to salvage the situation, but it was clearly useless. Very quickly, the wings behind her turned into particles and disappeared.

“My wings! My wings! Even if they’re fake, you can’t just dismantle them like that!”

Holding the fragments on the ground that hadn’t fully dissipated yet, Miss Insurance Mechanism looked utterly grief-stricken.

“Then the tail? Is that fake too?”

Looking at the silver-haired girl in front of her, Her Majesty the Demon Lord reconsidered the other party’s identity and reached out to grab her tail.

“No! The tail is real! You can’t touch it!”

Seeing the demonic claw reaching for her tail, Miss Insurance Mechanism jolted in fright. Forgetting about mourning her lost wings, she hurriedly retreated several steps back.

“Are you some kind of brat? Why do you want to grab and destroy everything!”

“Logically speaking, your wings were just too fragile… I really only pinched them lightly.”

Her Majesty the Demon Lord felt a bit wronged. She really didn’t use any force. And who would have thought that the thing behind you that flaps from time to time would be even more brittle than the potato chips I usually chew on.

“The tail is real! You’re not allowed to touch it! You have a tail too. You should know how sensitive they are when relaxed!”

Hugging her tail, Miss Insurance Mechanism glared at Eiru with vigilance.

“So who exactly are you? Did you lie to me before?”

Between those confusing statements earlier and her deliberate disguise to look like herself, Her Majesty the Demon Lord couldn’t help but start caring about the other party’s true identity.

“Anyway I won’t remember after I get out. Even if you tell me, it won’t matter, right? You’re not some insurance mechanism at all, are you?”

“Get lost! I’m your little sister!”

Facing Eiru’s questioning, the silver-haired girl across from her just made a face, her tone extremely unfriendly.

“Can we talk properly? Can you stop swearing?”
