~ Support & Read 17 Advanced Chapters on My Patreon! ❁❁❁❁ Having a piece of meat delivered to my doorstep, how could I refuse? Looking at Rias's shy expression, my lips curled upwards slightly. That night, after a fierce "battle," Rias successfully completed her transformation from a girl to a woman. ——— A few days passed in the blink of an eye. My days in the Gremory household were quite pleasant. I even got to tease the innocent Irina Shidou from time to time. However, today I had serious business to attend to. After searching for several days, I had found a Black Grade target. [System Target: Tiamat, the Chaos Karma Dragon; Task Grade: Black; Task Condition: Subdue!] Therefore, after informing Rias, I headed alone to the Familiar Forest. Upon sensing the aura of a Dragon King-level being, I quickly flew towards Tiamat's resting place. Speaking of which, I had never seen the Human form of Tiamat—the only female Dragon King among the Five Great Dragon Kings in this world. 'After subduing her, I must have her transform.' Just as I was pondering this, I had already arrived within Tiamat's territory. Sensing the Draconic aura emanating from me, Tiamat immediately let out a Dragon roar, attempting to warn me not to cross the boundary. "ROAR!!!" I paid it no mind. After all, all Dragons possessed a strong sense of territory, especially Tiamat, one of the Five Great Dragon Kings. Within the Familiar Forest, hearing Tiamat's roar, the creatures seemed to sense impending doom and fled the area. Even some individuals who were originally trying to capture familiars, upon realizing it was the roar of a Dragon King, scrambled away in terror, fearing for their lives. However, I remained oblivious to this, continuing to fly towards her location despite Tiamat's furious roars. The awakened Tiamat, sensing the unfamiliar Draconic aura relentlessly approaching her, couldn't help but become enraged. Seeing this, Tiamat directly assumed a battle stance, ready to face this unfamiliar Dragonkin enemy. However, upon seeing me clearly, Tiamat paused for two seconds, a hint of surprise in her heart. 'This is clearly a Human youth. Why is the Draconic aura on him so potent and strong? Just who is he!?' Just as Tiamat was curious about my identity, I walked up to her, continuously sizing up this female Dragon. Tiamat had the appearance of a Western Dragon—Her entire body was predominantly cyan, with parts adorned in purple. A pair of light purple Dragon horns grew from her head. While I was observing Tiamat, Tiamat was also sizing me up. 'I have no memory of this Dragon aura, and I've never seen this Human before!' 'However, He seems quite charming, and he even gives me a sense of comfort.' Tiamat grew even more curious. This was natural. After all, the stronger a Dragon, the more it could attract the attention and closeness of other Dragons. "Human, who are you? Why have you trespassed into the territory of Tiamat, one of the Five Great Dragon Kings?" Tiamat couldn't help but ask. "Let me introduce myself. I am Hibari Kyoya. My purpose in coming here is naturally to subdue you and make you my familiar. Why else would I travel all this way to find you?!" Without any beating around the bush, I directly stated my intentions. "What? You're Hibari Kyoya?!" Tiamat's Dragon pupils constricted, looking at me with disbelief. After all, my deeds were now known throughout the Three Realms—Gods and Devils alike! Killing the Fallen Angel Cadre Kokabiel, instantly defeating Katerea Leviathan, and single-handedly taking on both the Red Dragon Emperor and the White Dragon Emperor—I was practically a legend. Because Sirzechs and the others had kept it a secret, very few people knew about my Azure Dragon Power. But even so, my track record was still terrifyingly impressive. No one dared to underestimate me anymore. "Wait... Did you just say you want me—a Dragon King—to become your familiar? Are you insane?!" Recovering from her shock, Tiamat roared angrily, flailing her claws. "I'm quite serious! After all, among the Five Great Dragon Kings, you're the only Female Dragon. I'm not interested in those other four males!" I first pouted, then looked at Tiamat with a beaming smile. Tiamat: "..." 'Hmph~ So I should thank you for taking an interest in me?' Hearing this, Tiamat's massive Dragon eyes rolled dramatically at me. My remarks during the Three Factions Summit had spread throughout the Three Realms. Now he was even targeting her! "Don't think you can talk so big just because you defeated Vali and the others!" Tiamat roared through her massive Dragon maw. She was one of the Five Great Dragon Kings—Even if she died in battle, she would never submit to force. A Dragon's pride and dignity were not to be trampled upon. —— However, after observing me more closely, Tiamat's Dragon eyes shifted, and her tone changed as she spoke. "However, I can give you a chance. If you can truly subdue me, I can become your familiar. But if you lose..." Tiamat paused deliberately, then dropped a bombshell. "From today onwards, you must become my partner and stay by my side always. How about it?" After all, I was related to Dragon-kind, and possessed considerable strength. More importantly—I was quite charming. Tiamat had taken a liking to me. Hearing this, I looked speechlessly at this female Dragon. 'Damn, she's actually interested in me?' 'I came here to subdue you! How did you end up taking a liking to me and trying to subdue me instead?!' However, after thinking about it, I said with a playful expression, "No problem. But you have to let me see your Human form first!" Hearing this, Tiamat didn't waste any more words. Her Dragon form suddenly erupted in cyan flames. Amidst the flames, the cyan Dragon's figure gradually shrank, replaced by a tall, curvaceous silhouette. Tiamat's Human form gradually emerged—cyan hair reaching her waist, light pink eyes. The pair of cyan-purple Dragon horns on her head and the pair of wings on her back remained. Cyan scales formed armor across her chest—simply rule-breakingly beautiful. Her entire being radiated a Heroic and Valiant aura. The imposing chest armor outlined alluring curves, a beauty that made my heart tremble, making it almost impossible for me to look away. I hadn't expected Tiamat—the Chaos Karma Dragon—to be so stunningly beautiful in Human form. "Hmph hmph~ Stunned, aren't you, boy?" Tiamat glanced at me, her exceptionally beautiful face showing a hint of smugness and a confident, charming smile. My reaction greatly satisfied Tiamat's vanity. ❁❁❁❁ ~ 17 Advanced Chapters Available on My Patreon! https://p-atreon.com/dragonnx (Just remove the hyphen to access Patreon normally.)
