Time had lost all meaning here, allowing them to push their bodies and abilities far beyond what would have been possible in the real world. Akari stood beside Akeno, both of them breathing heavily after an intense final spar.
Akeno's dual wings were still slightly extended, her body glistening with sweat. The half-fallen devil had finally unleashed her full potential — Holy Lightning crackling with devastating power that blended her father's light and her mother's magic. She had gone all out, and Akari had pushed her every step of the way.
Akari raised both hands. A pair of ornate, gold-and-blue rings materialized around her fingers, glowing with a soft, soothing green light. This was her newly acquired Twilight Healing manifesting visually.
Gentle emerald energy flowed from the rings, enveloping Akeno's body. Cuts, bruises, and muscle fatigue vanished almost instantly. Akeno let out a soft sigh of relief as the healing light washed over her, restoring her strength and soothing her exhausted body.
Akari then turned the rings on herself. The same green light bathed her own form, easing the tiredness that had built up from the long session. Her muscles relaxed, her breathing steadied, and the faint ache in her limbs disappeared.
Akeno watched the process with quiet curiosity. She assumed this was simply one of Akari's hidden abilities and chose not to ask. There was something comforting in not knowing every secret — especially when the result was this effective.
Once both were fully healed and refreshed, Akari and Akeno walked back toward the main training area where the others were waiting.
Rias was sitting on the white ground, catching her breath after her own intense solo practice with the Power of Destruction. Koneko and Kiba were also resting nearby, clearly exhausted but visibly stronger than when they had first entered the dungeon.
Akari stopped in front of Rias and Akeno, a satisfied smile on her face.
"Rias and my lovely Akeno, both of you no longer need to train. You are now strong enough."
Rias let out a long, relieved sigh, her shoulders slumping as the tension finally left her body.
"Thank goodness… I really needed that rest."
Akeno, however, blushed deeply at being called "lovely" by Akari. The memory of what had happened during their private session — how Akari had transformed into a futa version of Rias and thoroughly impregnated her — flooded back.
Her cheeks turned a shade redder than Rias's crimson hair. She brought a hand up to cover her mouth, trying to hide her embarrassment, but the faint smile on her lips betrayed her.
Akari then turned her attention to Koneko and Kiba.
"Time to train the both of you."
Timeskip – Many Hours Later (Inside the Dungeon)
The white void was filled with the sounds of combat and heavy breathing. Koneko's Rook-enhanced strength had been pushed to new heights, her punches now capable of creating visible shockwaves even in this dimension.
Kiba had refined his Sword Birth to an impressive degree, creating and switching between multiple demonic swords with fluid precision.
Akari stood in the center, half-tired but still standing tall. She had trained both of them relentlessly, sparring with them one after another and then together. The effort had taken its toll.
She raised her hands again. The gold-and-blue rings of Twilight Healing appeared, emitting their soft green glow. First, she healed herself, the green light washing away her fatigue and restoring her stamina.
Then she moved to Koneko and Kiba, bathing them in the same healing energy. Their bruises faded, their muscles relaxed, and their breathing returned to normal.
Asia, who had been watching from the side while practicing her own support techniques in secret with Akari earlier, walked over quickly.
"Are you okay, Sis?"
Akari chuckled softly at the new nickname.
"Calling me Sis now, huh Asia? That's cool. But I'm fine."
She looked at the entire group — Rias, Akeno, Koneko, Kiba, and Asia — and gestured for them to gather.
"Everyone, hold each other's hands."
They formed a small circle, linking hands. Akari placed herself in the center and spoke clearly.
"Escape."
A bright white light enveloped all six of them. The Instant Dungeon dissolved around them, and in the blink of an eye, they reappeared inside the familiar Occult Research Club room in the old school building.
Only two seconds had passed in the real world.
The group stood there for a moment, adjusting to the return of normal time and space. They looked stronger, more confident, and far more prepared than when they had left.
Akari smiled at them.
"Good luck to all of you in the upcoming Rating Game."
Rias stepped forward, her expression sincere and grateful.
"Thank you for your help, Akari-kun."
Akeno, Koneko, and Kiba echoed the sentiment almost in unison.
"Thank you for your help, Akari-kun."
Akeno gave Akari a playful wink, her violet eyes sparkling with affection and a hint of their shared secret. Akari felt a small blush creep up her cheeks, but she quickly hid it with a grin.
Akari then took Asia's hand gently.
"Come on, Asia. Let's head home."
Asia nodded shyly, waving goodbye to the others as they left the clubroom together.
The door closed softly behind them, leaving Rias and her peerage standing in the quiet room, now significantly stronger and more united than before.
