Two days later, in Different Dimension ----
In a desolate area, Leo is currently confronting Rem.
"Boom!"
Rem, still dressed in a somewhat provocative maid outfit, exuded a ferocious aura, her face contorted in a grimace.
A single horn emitting white light was slowly growing from her forehead, making the aura emanating from Rem increasingly ferocious.
It's clear that Rem is trying to Oni Transformation again.
"Hang in there."
Leo exposed himself completely to Rem's ferocious aura, as if he were unprepared to expose himself to an invisible storm. Even though Rem's face was contorted with rage, he remained remarkably calm.
"Don't let the horn on your forehead lead you astray. Shift your attention away from the horn and focus on the surging power within you. Guide it to your limbs, using them naturally, like you would your hands and feet."
Leo gave Rem a lot of guidance, every word hitting the nail on the head. Rem followed his instructions with a troubled expression, trying her best to control the surging power within her and prevent herself from losing her way.
"Remember, go slowly. You absolutely cannot let the Oni Transformation power expand to its maximum point too quickly, or you will lose your mind very soon."
"Control the rate at which the power surges, and suppress it as much as possible."
"While this will reduce the power gained after Oni Transformation, it will also make it easier for you to control this power."
By now, Leo has almost figured out the true nature of Rem's Oni Transformation.
He discovered that there were some fundamental differences between Rem's Oni Transformation and that of ordinary Oni Clan.
Ordinary Oni Clan, including Ram, release their physical potential by activating their horns when they Oni Transformation, transforming that potential into tangible power to enhance themselves.
Rem is different; her horns are not limiters for unleashing her physical potential, but rather amplifiers for absorbing external power.
When Rem activates her horns and enters her Oni Transformation form, her horns begin to continuously absorb free energy from the outside world, channeling this energy into Rem's body. Rem who receives this energy instantly gains ten or even a hundred times more power than ordinary Oni Clan, causing her strength to surge exponentially.
This enhancement far surpasses that of ordinary Oni Clan, but it also makes one extremely difficult to control. One careless move can cause a person to fall into depravity, lose their way, and ultimately lose their reason, plunging into a state of rage and transforming into a true evil demon.
Tiamat is right. Whether it's Ram or Rem, they can both be considered transcendent beings of the Oni Clan, beings that have surpassed the "Oni" race.
Therefore, they all underwent varying degrees of mutation.
Ram chose the wrong Talent Tree; despite being Oni Clan, he is not good at physical combat, but is extremely talented in magic, making him a peerless magical genius.
Rem underwent a mutation in her Oni Transformation. Her horn, the greatest symbol of the Oni Clan, transformed from a limiter into an amplifier, allowing her to undergo enhancements spanning two levels. The extent of this enhancement was even more outrageous than some Longinus.
Upon discovering this, Leo quickly devised Training Plan, instructing Rem to consciously control her horns, the speed at which they absorbed external energy, and the flow of energy after it entered her body.
After this training, Rem's ability to control her Oni Transformation indeed improved at a visible rate.
"Ugh----Ahhh----!"
Over time, Rem couldn't help but let out low growls, and his eyes gradually turned red.
"Alright, that's all for now."
Seeing this, Leo suddenly flashed in front of Rem and flicked the single horn on her forehead.
"Bang!"
The impact, carrying Demonic Power, struck the horn that was emitting white light, causing Rem to feel a jolt in her forehead, her head to tilt back, and her whole body to fall backward.
Leo grabbed the little maid, put his arm around her slender waist, and stared at the single horn on her forehead.
After being impacted, the single horn quickly went silent, ceasing its outward growth and instead beginning to retract inward.
"Hmm----"
Only when the horn completely disappeared from her forehead did Rem let out a somewhat distressed sound and slowly open her eyes, which were no longer red.
"How are you feeling? Are you alright?"
Leo helped the girl, who had slumped in front of him, to her feet and asked with a smile.
"Y-yes—" Rem shook her groggy head, supporting her weak and sore body, and asked Leo, "How long did Rem last this time?"
"About forty-five minutes, I guess?" Leo glanced at the pocket watch in his hand and praised, "Not bad. That's enough time to handle high-level battles."
Unlike the Balance Breaker of Sacred Gear, how long Rem's Oni Transformation can last depends not on how much power the host has left to expend, but on whether Rem can firmly grasp the reins called "horn" on her forehead.
Once the Balance Breaker of the Sacred Gear is activated, even using its ability will incur additional costs. Therefore, even Leo and Vali Lucifer dare not say that they can last for half an hour in a battle that requires their full strength.
Rem is different. As long as she doesn't let go of the control over the opposite corner, those 45 minutes are real and won't be reduced just because she's fighting with all her might.
certainly----
"Considering we need to allow for some leeway, you'd better keep the Oni Transformation time under thirty minutes," Leo said seriously. "If it exceeds that time, it might become dangerous."
If Rem's Oni Transformation lasts for more than thirty minutes, the power within her body will surge to a level that is difficult to control. Not only will the burden on her body increase dramatically, but the impact on her will will also increase rapidly.
It can be said that after thirty minutes of Oni Transformation, Rem is essentially dancing on a piano line. Her body will become fatigued due to the prolonged Oni Transformation, and she will lose control of her power. As a result, Rem will lose control at an alarming speed.
Just like now, even though Rem stopped Leo from losing control, because she maintained her maximum Oni Transformation and endured the maximum surge of power, Rem was immediately exhausted and couldn't even stand up.
If she were on the battlefield, she would definitely not be able to handle the next crisis, and could be easily overtaken by some enemy she hadn't yet defeated.
That's why Leo gave her that advice.
"Always leave yourself some room for maneuver. If you only use your Oni Transformation for thirty minutes, that means you've exited the Oni Transformation form and will still have the strength to continue fighting. At worst, you can find a way to escape. Never exhaust yourself to the point where you have no strength left, because if anything unexpected happens, you could lose your life."
Leo patted Rem on the smooth shoulder and said something.
"As for the last thirty minutes, you can play however you want. During that time, you're no worse than your sister."
Upon hearing this, a relaxed smile finally appeared on Rem's exhausted face.
"Now, Rem is finally qualified to stand beside her sister and fight alongside her."
The blue-haired girl seemed only happy about it.
That pure heart made Leo take notice.
"No wonder those perverts in my past life were always clamoring that if true love existed in this world, it would definitely be blue. It seems like Rem is the best wife for them after all."
Leo sighed inwardly, his gaze towards Rem becoming somewhat intense.
"What's wrong, Lord Leo?"
Rem noticed Leo's gaze, tilted her head, and looked puzzled.
No, it's nothing.
99
Looking into those innocent eyes, Leo felt a little guilty and looked away.
He always felt that ever since he had tasted the forbidden fruit with Yukino Yukinoshita and Asuna Yuuki, his self-control had been declining rapidly.
These past two days, whenever he saw the young girls running around the manor with their long, white legs, he couldn't help but glance at them. The restless desire in his heart grew stronger day by day, and he could no longer resist the urge to be affectionate with his lovely family members.
"I feel like all my switches have been flipped, I wonder how long I can keep this up."
Leo felt somewhat melancholy.
If I continue like this, won't I become the next Issei Hyoudou?
"----Lord Leo, you'd better control your desires a little, especially at this critical juncture."
At that moment, a completely emotionless voice broke in, causing both Leo and Rem to look towards the source of the sound.
"Big sister."
Rem called out to the other person.
"Thank you for your hard work, Rem."
Ram walked slowly from afar, first offering a word of comfort to his younger sister, before glaring at Leo.
Why are you here?
Leo touched his nose and chose to change the subject.
I've been seen through by this perceptive maid!
" Ram is here to inform you." Ram continued to stare at Leo for a while before looking away, then said, "It's time for the Summit Meeting."
Leo glanced at the sky and realized that it had darkened sometime earlier.
"Have we arrived yet?" Leo murmured, then asked, "Where are the others?"
"Everything is ready," Ram said. "Only you and Rem are missing."
"Is that so?" Leo nodded and said, "Then let's set off."
On this day, all universities in Japan, including Kuoh Academy, celebrated a holiday.
Because it was a holiday, Kuoh Academy was deserted all day, but the high-level meeting between the Three Factions was still scheduled for the late night when no one was around, making the entire Kuoh Academy quiet and extremely silent.
Meanwhile, unseen by ordinary people, a crystal-clear barrier was silently unfolding, enveloping the entire Kuoh Academy.
--
This barrier is far stronger and more resilient than the Kokabiel attacked before, because it was jointly set up by the guards of the Three Factions, which is much stronger than the barrier previously set up by the members of the Sitri Peerage.
Guards from all sides had already arrived in advance, and each faction had dispatched a group of powerful individuals. These powerful individuals, working together, were far superior to a mere unproduced Sitri Peerage, turning the entire Kuoh Academy into a true impregnable fortress. It seemed that even if Kokabiel attacked again, he would not be able to break through this barrier.
Under these circumstances, the armies of Devil, angels, and Fallen Angel have completely surrounded Kuoh Academy. Representatives from each faction are waiting in the lounge of the New School Building. No one can enter the meeting room, and no one can leave until the meeting ends.
The atmosphere was tense and ready to erupt at any moment. It felt as if any mishap, conflict, or argument during the meeting could easily escalate into a Three Factions war.
In the minutes before the barrier opened, Leo and his group used the magic cube to jump to the Kuoh Academy. After going through heavy security checks and surveillance, they entered the New School Building and headed towards the conference room.
Although they didn't see anyone along the way, both Leo and the group of girls in their familiars could clearly feel that someone was watching them.
Therefore, the girls all tensed up, and influenced by the atmosphere, they didn't dare to breathe loudly. Only Leo walked here with a normal expression, looking calm and composed, and led his group of family members to the conference room.
The conference room door opened silently, revealing the scene inside to everyone.
The first thing everyone saw was a specially prepared table, which looked quite luxurious. Several imposing figures had already sat around the table, none of them speaking, creating a serious, silent, and heavy atmosphere.
Around the conference room, in the corners, Rias Gremory's Gremory Peerage and Sona Shitori's Sitri Peerage had already arrived and were exchanging glances with Leo and his group.
Rias Gremory and Sona Shitori nodded slightly in acknowledgment when they saw Leo appear.
At the conference table, both Sirzechs and Serafall looked at Leo; one gave him a gentle smile, while the other snorted and looked sullen.
Grayfia Lucifuge was standing next to the tea cart on Sirzechs and Serafall's side, seemingly in charge of the hospitality for the meeting.
Opposite Sirzechs and Serafall sat a man who had met Leo once before.
"You've finally arrived, lad from the Eligos Clan."
Ignoring the serious atmosphere, Azazel remained as flippant and nonchalant as ever, greeting Leo with a smile.
Behind him, Vali Lucifer leaned against the wall with his arms crossed, his gaze never leaving Leo since he entered, a slight smile playing on his lips, his eyes filled with the familiar fighting spirit.
Seated next to Azazel was a very conspicuous figure.
He was a man dressed in a luxurious white robe, with long golden hair, extremely handsome, with a golden halo above his head and six pairs of golden wings on his back.
He seemed to be radiating light, with a gentle and kind smile on his face, instantly attracting the attention of most of Eligos Peerage.
Leo glanced at the other person a few times, silently thinking to himself.
" Archangel Michael."
I finally met the current leader of the Heaven.
