Demon King – Chapter 380 – The Silver-Haired Girl Who Lost Her Mind

They had been sitting and chatting for who knows how long when Eiya, who was resting her head against Eiru’s chest, suddenly trembled a few times. At last, there were signs that she was about to wake up.

“Awake? If you’re awake then hurry up and get up to brush your teeth and wash your face. You’ve been pressing on me for so long I’m about to starve flat.”

Facing her sister’s hazy gaze, the Demon Lord, whose stomach was already growling from hunger, gently pinched her sister’s cheeks a few times and urged her to get up.

“But you really slept for a long time today…”

While helping her sit up, Eiru complained helplessly.

Eiya normally didn’t have the habit of sleeping in. Her daily routine could be said to be very healthy. From childhood until now, whenever the two of them slept together, barring special circumstances, Eiya was usually the one who woke up first…

Like today, sleeping until she naturally woke up, and even waking up this much later than Eiru, this was the first time it had ever happened.

Yawning, half-asleep and half-awake, Eiya narrowed her eyes and hugged her sister’s body, rubbing against her in a spoiled, clingy way a few times, with absolutely no intention of getting off Eiru.

Letting out a sigh, Her Majesty the Demon Lord had no choice. She could only circulate a bit of her magic power and lift her silly little sister up in a princess carry, preparing to take her to the bathroom to wash up. If she let her keep sleeping, the two of them would both pass out from hunger.

Yuki had already gone ahead to prepare food. Standing by the stove, he watched as a silver-haired girl held another girl of similar build in this posture. That subtle scene really gave him a whole pile of complaints he wanted to spit out in his heart.

“Are you… feeling unwell?”

They had already reached the bathroom, yet her sister was still wearing that half-asleep, intoxicated look. Eiru sensed something was off.

“Nope. Sister, hug hug~”

Eiya was still acting like a spoiled little girl, with no sign of discomfort on her face. But that expression left her sister completely puzzled.

‘Why does she look like a cat high on catnip? It can’t be that the lavender is still taking effect, right? I’m already fine… forget it, maybe this girl is suddenly feeling extra clingy. Better not randomly guess a girl’s thoughts.’

Putting the toilet lid down, Eiru gently sat Eiya on it. Then she used magic to heat a basin of cool water to warm, wet a towel, and helped her wash her face, just like when they were little.

After brushing teeth and washing up, Eiya was still wearing that confusing, catnip-high look, resting her head on Eiru’s shoulder and rubbing against her affectionately.

‘I really give up. What is wrong with you today? I was originally going to ask you why lavender affects you too… but looking at this situation, whether I can even have a normal conversation with you today is already questionable.’

“What’s wrong with Little Eiya?”

Yuki brought the dishes to the table and asked in confusion. Before, he thought it was just affectionate sisterly interaction, but now even he could tell something wasn’t right.

“Probably because of the lavender. She hasn’t acted this spoiled toward me since I started middle school… or maybe she’s just gone dumb.”

Helping Eiya sit down on the chair, Eiru deliberately said something provocative while looking at her sister, who was acting strangely childish, trying to see if she was pretending.

If it were the usual Eiya, hearing that last sentence, she would have exploded on the spot and demanded an explanation. But right now, she was still acting like a spoiled little kitten, which only made Eiru’s headache worse.

Since she wasn’t pretending, that meant this girl’s head really wasn’t right at the moment. Could it be that when I inhaled lavender back then, I was also in this kind of state… Thinking of that, the Demon Lord suddenly felt a chill for no reason.

“Lavender? What’s wrong with that stuff?”

Hearing Eiru mention it, Yuki suddenly remembered that Eiya had mentioned this thing to him before.

At the time, he hadn’t figured out what it meant at all. After all, just being given a term, who the hell knows what it refers to? Now that he heard it again, of course he wanted to ask in detail.

“According to Little Ya, lavender is like catnip to me… but because I black out and lose my memory every time, I don’t really know what the exact situation is.”

The Demon Lord held her head. This inexplicable constitution really gave her a massive headache.

Of course, if Eiya were still conscious, as the Demon Lord girl Research Master, she would definitely have pointed out the problems Eiru was leaving out.

After all, she had conducted N experiments back then. Not only did she find out that lavender’s effects on Eiru were divided into three stages, she even tested the different required doses and intake times needed to enter each stage…

So it was fortunate that Eiya wasn’t a yandere. Otherwise, she could have completely relied on these research results to make her dear sister obedient to her for the rest of her life.

“Uh… so both you sisters are like this? Is it congenital?”

Hearing about this kind of constitution for the first time, Yuki silently noted down this key point.

After all, lavender was extremely common everywhere now, in things like air fresheners. It was definitely necessary to be careful. Even if he wasn’t afraid of his little girlfriend going crazy and embarrassing herself, he was afraid she’d black out and get abducted or tricked away without knowing it.

“Of course not! When I was still human, I wasn’t afraid of this stuff at all… even when I was using a male body, lavender didn’t affect me.”

Because this might be related to why she turned into a girl, Eiru had privately done this small experiment before. In male form, or rather in a human state, lavender had absolutely no effect on her. But once she switched to her true demon race form, she didn’t remember anything after that.

“So this stuff is some kind of demon-specific weapon? Then what about Little Eiya? Is she also a demon? Your whole family wouldn’t actually all be demons, would they?”

The amount of information was a bit much. As Yuki organized it in his head, he couldn’t help but speculate.

“No. Little Ya is a pure human. I’m the only one who became a demon later because of an accident.”

Her Majesty the Demon Lord denied it. Her sister’s medical reports were all there, and combined with the Demon Lord’s ability to sense her own kind, she was very certain that she was the only demon in the world.

“Then why does she…”

“How would I know? I’m puzzled too… Don’t even talk about when she was little. Even during summer vacation, she had no reaction to lavender at all. She even kept using lavender-scented spray to torment me every day…”

Looking at Eiya, who was clinging to her shoulder like an affectionate kitten, the Demon Lord sighed helplessly.

Eiru still remembered what happened before she blacked out. She clearly remembered her sister saying “let’s die together”. From that alone, it was obvious that Eiya knew she herself would also react to lavender.

I’ll ask her in detail after she wakes up. In this state, I can’t get anything out of her anyway… Eiru felt a vague unease in her heart. She always felt this wasn’t a good sign, but she couldn’t say exactly what was wrong.

“Forget it. Stupid Yuki, help me get a plate. Little Ya can’t eat by herself like this, so I’ll just feed her…”

“You really dote on your sister…”

“Nonsense. She’s my sister. If I don’t dote on her, who would I dote on? Besides, I can’t just let her starve like this, can I?”
