My Overpowered Bunny Girls

Hours later, when the party had finally dispersed—Garrett heading home , Dillon to the noisy, crowded guild barracks, and Elise returning to her pristine, quiet private quarters at Celestial Peak—the tiny apartment finally settled back into its usual, comforting stillness.

Lucy had passed out entirely on the mattress, one small hand resting protectively over her glowing star-shaped nightlight, the other loosely clutching her crumpled, graphite drawing of dragons and long-eared warriors. The sheer adrenaline of the summoning had utterly exhausted her, and she had barely managed to swap into her pajamas before collapsing into a deep, dreamless sleep.

Nathan sat alone at the small kitchen table, Moonlight resting securely against the wall beside him. The Leyline Ring hummed a low, comforting vibration against his finger. The Mana Capacitor strapped to his wrist was actively recharging, its internal crystal slowly refilling by pulling ambient mana from the cool night air. Outside the window, the capital’s sprawling lights glittered sharply against the pitch-dark sky, while the monolithic, obsidian silhouettes of the Towers loomed on the distant horizon like jagged teeth.

His three summons were resting in their small forms at the foot of the bed. Mirko—soft green fur, pink eyes shut tight, curled aggressively into a tight ball near Lucy’s pillow, occasionally twitching as she chased phantom enemies in her sleep. Kuro—sleek black fur, stark white mask-markings, resting as a silent, watchful shadow near the very edge of the mattress, her breathing shallow and perfectly controlled. Shiro—orange-red fur heavily marked with dark tiger stripes, the tiny horn-tufts on her ears catching the faint starlight from the window. She had positioned herself with deliberate, mathematical precision exactly equidistant between the other two, calculating the optimal defensive placement for the pack even in sleep.

It was Shiro who quietly shifted back into her humanoid form, the transition utterly silent.

She approached him in the dark. She didn’t drop to one knee this time—her earlier martial salute had been for her naming, a highly formal, public acknowledgment of his absolute authority. This was something different. Something infinitely more personal. She stood before his chair with her hands clasped loosely behind her back, her posture impeccable, her golden eyes glowing softly in the dark room, steady and unblinking.

"Young Lord. I wish to speak plainly with you."

Nathan nodded, leaning back in his creaking chair, pouring two glasses of water and pushing one across the table to her. "Go ahead, Shiro."

She ignored the glass. "I was born directly from the dragon’s heart. Vorlagrath’s ancient fire gave me my physical form, my absolute power, my class. But his memories... his memories gave me context." She looked toward the window, at the distant, looming Towers. "I know exactly what the Shepherd did to our people. I know what was systematically stolen—the grand kingdom of Drak’thar, the beautiful alliance between dragons and Demi-Beasts, the countless mortal races who fought and bled and died in a war they never asked for. I know that this System is merely a fragmented piece of something much larger, a desperate, broken failsafe that rescued our erased souls from total extinction and gave us a cruel new life as bounded summons."

She paused, turning her burning gaze back to him, the sorrow of a dead civilization bleeding into her voice. "And I know that you carry the ember. The promise that the fire will not be extinguished."

Her golden eyes locked onto his, and Nathan saw something terrifyingly ancient in them—the heavy, unbroken echo of a dragon king’s final, desperate charge, passed through fire and time into a new, lethal vessel.

"I am your sworn vassal. Your martial artist. I am your sword and your absolute fist. Whatever comes for us next, I will face it at your side without a single moment of hesitation. I will train until my physical body breaks, and then I will heal and train more. I will fight until my flames completely gutter, and then I will dig deep into my core and find new fire. This I swear to you, Young Lord. On the dragon’s heart that forged my life. On the ember that refuses to die."

Nathan held her intense gaze. The sheer weight of her midnight oath settled heavily over his shoulders like a lead mantle—crushing, but grounding.

He thought of Mirko, who had stubbornly sworn to be his shield on the day of his graduation, who had stared down a Dread Knight, a Shadow Wyrm, and a Level 51 Berserker, and had never once taken a backward step, even when her armor shattered. He thought of Kuro, who had sworn to be his blade in the suffocating depths of the Whispering Dark, who had executed a high-level Court operative in cold blood to save his life and had never spoken a word of it again.

And now Shiro—born from pure, unadulterated dragon fire, named for the blinding white heart of the ember, swearing absolute fealty in the dark with the formal grace of a warrior who had been waiting centuries for a lord worthy of her loyalty.

"I don’t need oaths, Shiro." His voice was quiet, so as not to wake Lucy, but it held the steady ring of absolute certainty. "I don’t need you to swear on ancient dragon hearts or dying kings. I just need you. All three of you. Mirko. Kuro. Shiro." He looked toward the bed, where Mirko’s green ears had perked straight up despite her apparent sleep, and Kuro’s dark eyes had slid fully open in the gloom. They were listening. They were always listening. "Whatever comes for us—the Cleansing, the Court, the Shepherd—we face it together. That’s not an oath. That’s just... what we do."

Shiro was completely silent for a long moment, processing the rejection of formality in favor of genuine family. Then, she slowly inclined her head—not the rigid, formal bow of her martial salute, but something smaller. Softer. Intimate. "Together, then. That is an oath in its own unique way, Young Lord. Perhaps it is the strongest kind."

’She is very formal,’ Kuro observed smoothly through the psychic link, no longer pretending to sleep. ’But her sincerity is genuine. She means every single word.’

’I like her!’ Mirko added, her mental voice bright with aggressive enthusiasm, completely abandoning the pretense of slumber. ’She deeply respects seniority! She actively called me her senior! Eventually, she will acknowledge my complete and total superiority in all tactical things! It is only a matter of time!’

’That may take some time, Mirko,’ Kuro noted dryly.

’I am highly patient! I can wait! I have been waiting my entire existence for a proper, respectful junior! Well, I have been waiting since Kuro was summoned, but Kuro flatly refuses to acknowledge my superiority! She says things like "you are loud" and "that is not a viable strategy"!’

’Those things are objectively true,’ Kuro said calmly.

’They are not the POINT!’

Shiro’s lips twitched—the very first genuine smile Nathan had seen from her. It was small and incredibly fleeting, but unmistakable. "The bond between you is remarkably strong. I can feel the weight of it through the link. It is... warm. Familiar. Like coming home to a place I have never actually been."

"That’s the link," Nathan said softly, tapping his temple. "It connects all of us. It gets loud, but you’ll get used to the noise eventually."

"I already am." Shiro turned toward the mattress, where Mirko and Kuro waited in their small forms. "I should rest. Tomorrow, rigorous training begins. The Young Lord’s enemies will not wait, and therefore, neither shall I."

She shifted seamlessly back into her bunny form and hopped effortlessly onto the bed. She settled exactly between Mirko and Kuro, her golden eyes sliding shut, her breathing slowing to a steady, meditative rhythm as she began to passively cycle the dragon core within her.

Nathan watched his three summons for a long time in the dark, the reality of the morning slowly encroaching.

Green. Black. Orange-red.

Knight. Assassin. Martial Artist.

Three embers of a raging fire that had stubbornly refused to die, carried across centuries of darkness by a System he still didn’t fully comprehend. The war was coming to their doorstep, but looking at them, Nathan felt a profound sense of peace. They were ready.
