The Mark of the Succubus

“What is this!?”

Seeing the mark on my lower abdomen, I couldn’t help but widen my eyes.

This… this thing looks just like English!

I’ve seen it in some works that can’t be broadcast!

As a former healthy male, I had some interest in this kind of thing, so having a little knowledge is understandable, right?

But how can such an erotic thing appear on my body!

It’s really hard to accept!

I really don’t want to accept that I’m a succubus… but the facts are right in front of me.

Just now, I suddenly lost control and kissed the young lady. It was probably the succubus constitution acting up…

They say succubi absorb people’s energy. The young lady must have had her energy drained by me, which is why she became so weak.

And it’s precisely because I absorbed her energy that my own power increased significantly.

No… maybe my influence on her doesn’t stop there.

Thinking back carefully, I’ve always felt the young lady was somewhat precocious.

Perhaps that’s also an effect of the succubus constitution.

…The impact on teenagers is immeasurable!

“It seems you’ve accepted this reality.”

“It’s all my fault… It’s because of me that the young lady ended up like that…”

I bowed my head deeply.

“I won’t allow you to blame yourself. That would be an insult to Elizabeth.”

Margaret interrupted me.

“The constitution is uncontrollable. Besides, before you were stabbed today, you didn’t show any harmful traits. You mostly had a strong human aura, at most inexplicably making people feel very close.”

Saying this, she looked me up and down again.

“Probably something that ghost did amplified your demonic side.”

Margaret’s reminder made me think of that crucial item.

“…The dagger!”

I knew why that dagger looked so familiar… Its design was exactly the same as the dagger that can turn people into monsters, right? Only the color and patterns were a bit different.

“So this time, their goal in invading the academy was to awaken your demonic side. The demon clan has many more tricks up their sleeves than we can imagine.”

…

I fell silent.

After a long while, I looked at Margaret with pleading eyes.

“What should I do, Margaret the Doraemon?”

“What the hell is Margaret the Doraemon… I’m not as omnipotent as that blue fatty. Let me ask you first, do you have any bad urges right now?”

I shook my head.

“…Not for now. But I’m not sure if this is just a temporary state after absorbing the young lady’s energy.”

“…Is that so? Then it’s better to keep observing for a while.”

“But in that case, if I lose control again today and hurt the young lady…”

“About that…”

Margaret fumbled through her small handbag and soon pulled out a wristwatch, handing it to me.

“Wear this. If you do anything excessive, the watch will detect it and inject you with a sedative, forcibly calming you down… That way you don’t have to worry about hurting Katerina.”

…She even pulled out such a tool, and you still say you’re not Doraemon?

After putting on the watch, I complained internally.

“Oh, right. If you two truly decide by your own will to engage in that kind of behavior, just press the adjustment button twice, and the injection function will stop for three hours. How thoughtful of me, right?”

“Thoughtful is nice, but…”

“Don’t be this thoughtful in such matters!”

I shouted, my face bright red.

“Hee hee~”

—My anger was met with Margaret’s smirk.

“Ahem, anyway, for now you need to cooperate with me more. I’ll do my best to investigate your body and find a solution.”

“…Yes, thank you.”

I bowed to her, my body at a perfect ninety-degree angle.

“Oh, don’t be so formal. I can’t get used to that.”

Margaret waved her hand, signaling me to rise.

“I’m not a noble now, and we’re both reincarnators, no need to be so reserved.”

“But… I’m really grateful to you this time. Without you, I really wouldn’t know what to do…”

In the worst case, I might have to leave the young lady.

Nothing is more painful than hurting her with my own hands.

“You’re so earnest and honest, no wonder Katerina likes you so much…”

Margaret scratched her head and reorganized her words.

“Listen, think of it this way: we’re just mutually benefiting each other. You’ve also helped me with my investigation, haven’t you? If not for you, Elizabeth would never have come to this school.

Besides, you’ve helped her in many ways, right? When they were alone, she told me about you. I was so jealous. Truly worthy of a succubus.”

“Ahaha…”

Such blatant teasing left me with nothing to say…

“Alright, alright. If you really feel you’ve wronged Katerina, then think of a good way to make it up to her.”

She had a point.

But how should I make it up to the young lady?

“Hehe, I knew you’d be troubled about this. So I prepared something in advance for you.”

“…?”

Margaret started rummaging through her small bag again.

Then… she actually pulled out a pink dress!

“Are you really not Doraemon? How did you fit that dress into that little bag?”

“Don’t worry about such trivial matters. Anyway, listen to me: wear this, and Katerina will definitely be happy.”

With that, she unfolded the dress.

I took a closer look—it was a nurse uniform!

And the hem was very short! There were inexplicable cutouts at the chest!

“…You want me to wear this and go see the young lady?”

Hearing my doubt, Margaret was unperturbed, instead placing her hands on her hips:

“Of course.”

“…”

But I had to admit, the young lady might really like this…

From before, she had a particular fondness for making me wear revealing clothes…

This succubus constitution is truly heinous! What has it done to my pure young lady!

My heart resisted, and wearing this dress might overexcite the young lady, harming her body.

But it was true that it would make her happy.

Despite some hesitation, I still took the dress.

“It seems you’ve made up your mind~ Then I won’t disturb your private time~”

With that, Margaret smirked and fled the room.

Leaving me alone, staring at the nurse uniform in my hands, lost in thought…

…

“Hehe, no need to thank me, my comrade.”

In the corridor, the little black seaweed proudly puffed out her small chest, looking smug.

Beside her, the grey maid, though not understanding what she was saying, still wore a doting smile.

But in this harmonious atmosphere, an uninvited guest intruded.

“Thud.”

In an instant, the maid beside the little seaweed fell unconscious.

“…! It’s sh…”

“Thud.”

Before the little seaweed could finish her words, she too collapsed.

The uninvited guest then groped around the little seaweed’s body and pulled out a black box emitting a purple glow.

Then, she revealed a chilling smile…

“Finally got you… My ‘Heroine’.”
