Demonic Dragon: Harem System

Strax woke up the next day, remembering almost nothing of what had happened. After all, it had been an intense night of sex, and even his hips ached from the vigorous movements he had made. He left the bedroom without waking Beatrice and descended the stairs. The soft morning light had already penetrated the mansion's windows. He didn't go for breakfast; he just left, feeling a familiar presence.

"I was sure you'd come earlier," Strax said, seeing the Phoenix hovering. "I wanted to, but the brat caused a huge problem at that mansion. Knock some sense into her; she's waiting for you," Xyn said and flew ahead. "At least you let me talk a bit..." Strax murmured.

"She's gone for two days, and the first thing my sword tells me is to knock some sense into her. Seriously... what am I going to face today?" He lowered his head and started walking, holding a carrot in his hand. "Come on, girl, we have quite a day ahead," he said, giving the carrot to Apocalypse and mounting her.

"I had sex again... and still, the System hasn't increased my cultivation. Dual cultivation skill? Shouldn't this improve my cultivation speed? I feel like I'm falling behind," he thought, galloping towards...

Not much time passed before he approached the Family Mansion and saw a strange scene. The gate was ajar, which was unusual, and in the distance, he heard a faint rumble and sensed an aura. His eyes detected a large concentration of Mana coming from the main building... "Xyn... you could have told me to come more prepared," he murmured and dismounted Apocalypse.

"Stay here, it could be dangerous," he said, stroking her neck. "I'll be back soon."

As he approached, each step he took made him feel an invisible pressure coming from the mansion... "Holy shit," he said and opened the door.

Upon entering the mansion, Strax encountered a scene that left him slightly dazed. The entrance hall was somewhat destroyed, with overturned furniture and combat marks on all the walls. Four of his siblings were lying in different corners of the room, even those who had been punished were there, something that already aroused Strax's suspicion—they were visibly injured.

Looking at the epicenter, six swords were attacking Xenovia while only her aura held off six other people... But with just one look... All of them were sent flying, breaking the rest of the house, when he saw one of the older women... It was one of his sisters...

"Repeat what you said," Xenovia's voice echoed, causing a strange chill to run through all his hairs, then all the windows shattered.

Her eyes burned with fury, her firm posture, and her face marked by disgust remained in Strax's mind. He had never seen such rage, such a feeling of hatred... such a bad sensation. Her fists were clenched at her sides, and her breathing was heavy as if she was trying to control an uncontrollable anger.

"Xenovia?" Strax called, his voice carrying a mix of fear and caution. After all, he could be a target if she didn't control herself.

She turned slowly to him, her eyes still flashing. "Finally," she said, her voice low and laden with tension. "You're quite late." Strax heard this and raised his eyebrows, "But what happened here? And how am I late? Xyn warned me about you not ten minutes ago!" he asked, taking a few hesitant steps towards her.

"Since you've arrived, I'll give you a lesson," Xenovia replied coldly. "A lesson they all needed to learn."

"This is scaring me," he murmured. Strax looked around, his eyes scanning his siblings' bodies. They groaned in pain, some trying to get up but failing. The mansion looked like a battlefield, and he knew only Xenovia could have caused such destruction. "What did they do?" he asked, trying to understand the cause of such fury.

Xenovia closed her eyes for a moment, taking a deep breath before answering. "They defied my orders," she said, omitting some details. Strax felt a chill run down his spine at those words. He knew Xenovia was relentless, but the intensity of her anger was terrifying. "And you... resolved this with violence?

I mean, I'd do the same, but what was so extreme for this to happen?" Strax questioned, looking at the unconscious bodies...

"Tsk, they were bad-mouthing you," she murmured so low that Strax couldn't hear, and in front of him, a mission appeared.

[Legendary Mission Opened – A Sister's Love.]

"What the hell? I mean, what the hell is this! I expected something like this, but now? What happened here!" Strax screamed internally. He was now curious. What had those idiots done for him to receive this notification?

What did they say?

He stared at Xenovia with a really bizarre look, something like (0-o).

"There was no other way," she replied, her voice now more controlled. "They needed to understand that their actions have consequences," she said, turning towards the exit. "Come on, you need to train." She continued walking while Strax remained in that scene... "I hope you all die, I don't care," Strax said, smiling and running out. "My dear sister, wait for me!" he said in a very fawning tone.

Hours later, after leaving his injured siblings to fend for themselves, Strax and Xenovia were in the Training Room.

"Let's begin," Xenovia said, assuming her usual stance, and once again, they started a hand-to-hand combat session. Strax positioned himself in front of her, and she advanced, pushing him to his limits. Her blows were precisely calculated to test him in the most efficient way possible, focusing on his vital points.

"Xenovia," Strax asked while skillfully dodging her strikes, "why are you training me like this?" He summoned an ice sword, which for the first time managed to block one of the wind blasts Xenovia created by slicing the air. "You need to become strong," she said seriously, her tone slightly irrational.

"I want to become strong, but not without knowing what I'm fighting against," Strax said, breaking Xenovia's attack again.

"Something is wrong," she commented, this time advancing on him before he could process what she had said. With a wooden sword, she attacked, but his ice sword was already prepared to parry her strike. "If something's wrong, tell me," Strax said, his eyes shifting from merely defending to attacking. His ice sword traced a path towards impact.

*CRACK*

The wooden sword of the woman in front of him split in half, flying in various directions. "You've improved," Xenovia said, but that wasn't what he wanted to hear. "Xenovia, stop hiding things from me," Strax said, approaching her. "You wouldn't send me back just because you're worried about me, nor would you put me through training without a good reason.

If you were really concerned, you wouldn't even let me leave this mansion." Strax's eyes pierced into hers, and she was at a loss for what to do. She wasn't used to dealing with these issues; dealing with people was not something she was good at.

"I-I..." She tried to say something, but nothing came out. "Ah~" Strax murmured, looking at her again. "If there's something I need to worry about for the future and you can't tell me, give me a hug," Strax said seriously. "Let's take advantage of the beautiful sister I have, let's see if this works," Strax thought.

He had already confirmed it with the Mission he received; he was making this scene just to advance with Xenovia.

Xenovia pondered for a second about speaking, but then she just dropped the sword and approached Strax, hugging him tightly. Strax held her firmly, feeling her entire body. "Is that all?" Xenovia said, but it didn't seem like she wanted to pull away from him. On the contrary, she was holding onto him, not the other way around. "Sister, you're the one hugging me," Strax said with a charming smile.

She looked at him, confused, but soon she saw that he wasn't even hugging her; it was she who was holding him tightly, feeling his warmth, his scent, his heartbeat.

She quickly let go and pushed him away, blushing furiously. "W-what was that?" she asked herself, completely embarrassed and not knowing what to say. She was just trying to figure out where she had lost control for that to happen. "It seems like you like me," she heard, the man's voice entering her ear and going straight to her heart, which began to race. "L-liking y-you?" she said quickly.

"Hm? Isn't it obvious? Showing me that cute expression clearly means you like me, the mighty Xenovia blushing," Strax said with a seductive smile as he began to approach her. He quickly grabbed her hand and pulled her to his chest, hugging her for real now, making her feel his entire body just as he had felt hers. "I don't know what worries you, but if this calms your heart, it's all right.

I trust you, little amethyst, but know that I also have my goals," he said and whispered in her ear, "And you are one of them." Xenovia's entire body trembled as a message appeared in front of Strax...

[Mission Advanced]

Before he could continue, he felt something... His sister was hugging him much tighter than usual. "Hey, are you okay?" Strax asked, and she murmured, "The training is over." She then separated from Strax, quickly disappearing, even forgetting her black sword.

"Xyn, did I do something wrong?" Strax asked, and the bird flew around him. "I'd say you did more than necessary. What do you mean, 'one of my goals is you'? Was that a flirt?" she asked, and Strax just laughed. "Let her have her own thoughts. Maybe I was talking about her strength," he shrugged.

"I'll be back tomorrow," he said, leaving the Training Room.
