The Incubus System

"Before you go. Can I ask you a few questions?" Nathan's voice broke my mind. His sharp gaze didn't change. From his emotional status, I guessed he was curious about what was going on. Besides, prom night parties usually didn't serve alcohol so I was sure he could predict that we were the ones who gave Jenny.

"Sure," I answered in a casual tone.

"Do you know who her prom date is?" he began his interrogation. His anger was clear from his eyes. I could imagine how Nathan broke that demon's neck mercilessly even though the demon was still in his human form. I could understand this since I was in the same position as him when Celia came home after midnight with Bern a few months ago.

"Sorry, we don't know him. He only said his name is Damon and---" I shrugged

"That's all..."

He turned his gaze to Celia, indicating he was asking her the same thing.

"I don't know him either."

He sighed, trying to swallow his anger.

"Then may I know why she ended up with you guys?" Realizing his ambiguous words, he raised his hands slightly, gesturing he didn't want to offend us.

"Don't get me wrong. She told me that her boyfriend brought a car. I know she lied to me. So I want to know what happened to her?" he explained his point.

"I saw her trying to order a Guberr at the entrance and she didn't get it. Demon attacks are getting more frequent these days. So we took the initiative to give her a ride." I purposely mentioned the demon's attack to find out his reaction.

"As for what we've done, we mostly only accompanied her to chat and drink. We didn't know she had a bad alcohol tolerance. Sorry for that." I took the initiative to explain it before he asked.

Upon my words, his gaze turned cold. His killing intent was clear as well as his grudges. It even made Celia grab my hand out of fear.

"Yeah... The demon is indeed very dangerous. Especially that famous great demon..." he muttered.

"I think Jenny should be more careful with strangers. For whatever reason," I added in a casual tone to dispel this tension. I didn't know his reaction could be that bad, especially since I was the first person he thought of.

He huffed and tried to relax his facial expression.

"I will scold her for her stupidity after this. By the way, thank you for taking my sister home."

"No problem." In contrast to Jenny, judging from his statement, Nathan seemed more careful than his reckless sister. Well, he was a demon hunter after all.

"Thank you. I owe you one. If you need any help, just tell me. I'll help you as best I can."

"I will come to you if I need it," I said. I didn't know if he would keep his word or not, but I was not going to waste this opportunity, in case I needed him. Besides, his sister owed me her life.

"It's getting late now. We'll excuse ourselves," I ended our conversation.

"Okay. Take care." Then we turned around and walked to the car.

Realizing that there was something strange from our conversation, Celia glanced at the front door to make sure Nathan had closed it before he turned his gaze to me.

"Brother?" she whispered. She knew I wasn't someone who accepted random help from strangers, so she was sure there was something different about Nathan.

"He is a demon hunter. An advanced one," I said without stopping my steps. No, judging from his level, he may be a top advanced demon hunter.

Celia looked surprised and took another glance behind us before she returned her gaze to me. She opened her mouth and was about to speak again, but I pressed my index finger on my lips and pointed at the car, asking her to continue our conversation later.

After we got into the car, we closed the partition and the car moved.

"Do you know where he went before?" I wanted to ask this directly but was afraid he would suspect me. Besides, we just met.

"I heard he worked at the Kingdom of Serpent Rock."

"I see..." I muttered. Again I was deep in thought. Although not sure, maybe... Just maybe, he wasn't a Nephilim. But because he got a stronger vaccine from that kingdom. Even if it was just a guess, I hoped it was true. I didn't want to fight with the other Nephilim if I could.

"Brother, is the Advanced Demon hunter that bad? You look more cautious than usual." Finally, she said her question.

"He is a high level. Even his level exceeds Mrs Clea. So I have to be careful with him. After all, the association must have summoned him for a purpose." And I guessed it has something to do with me.

"If both of you meet on the battlefield one day will you fight each other?" A trace of worry was evident in the tone of her voice. This was why I accepted his offer, at least, I could use it to talk to him someday. But this was in the worst case where he already knew Damian and the great demon were the same people.

"Yes. I would avoid it if I could. But I guess the association called him because of me," I said. This worried me a bit since I kept appearing around Lightglen City, Nighthallow City and Ironshade Town.

'I think I'll have to show myself in some other country to break their concentration.' I just needed to show myself briefly with some witnesses who saw me slaying demons or something. Then came back with my portal.

'I should read some of my woman's mind then.' I had never been abroad before. Except for Kingdom of Serpent Rock, of course. So I had to find out about it from their memories. Well, they were rich so they should have gone on vacation to a country or two at least.

"I hope that doesn't happen. I just fixed my relationship with Jenny. I don't want to lose her... " she said in a gloomy tone. Indeed, my identity made things even more difficult. But with this, I could move faster than Demon Hunter. Not to mention, I didn't have to bow my head to the Senate and make my decisions more freely.

"In that case, it all depends on his decision. I just get rid of whoever stands in my way. Whoever it is." Even though my tone sounded relaxed, it was a serious one.
