At this moment, unprecedented doubts welled up within the Rias of this world.
Just how strong was her parallel world self?
Although the Rias of this world had asked, she hadn't received an answer.
However, she had to be very strong, at least reaching the level of a Satan.
No... based on the combat methods shown by her parallel self, she might even be on par with her brother and Satan Ajuka.
The Rias of this world speculated, yet she didn't realize that her vision was still too narrow.
True, Sirzechs and Satan Ajuka were Transcendents; in terms of combat power, Sirzechs could fully enter the world's top ten once he revealed his Devils True Form.
Given her perspective, that was probably the limit.
Dragon Gods, and even those beyond Dragon Gods—it already exceeded her imagination.
It was precisely because she understood this world that she was even more unable to see the world beyond the circle.
"Take a good rest."
Rias smiled and said, "Afterwards, I will teach you my combat method, the Hakai Hōteishiki."
"Is the training going to continue?"
The Rias of this world blinked and couldn't help but ask.
"The next part won't just be pure training."
Rias explained, "The reason for such high-intensity training was entirely to make up for your lack of foundation. The Hakai Hōteishiki will be taught to you through inheritance. This requires not just day-after-day training, but also sufficient wisdom and knowledge."
Wisdom and knowledge... the Rias of this world pondered slightly.
If that was the case, as a noble among Devils, it shouldn't be a problem.
But—
During this period of training, she had gained some understanding of her parallel world self.
The Hakai Hōteishiki she spoke of was likely not that simple.
Despite this, she still had confidence—a confidence born from being a noble among Devils when compared to others.
In reality, by the age of three, Rias had already possessed a vision that surpassed Ajuka's. While the depth of her knowledge wasn't as great, her breadth of knowledge was even higher than Satan Ajuka's.
As for the so-called 'noble's knowledge,' what she had learned was only at a kindergarten level.
If one were to compare, Ajuka should be used as the standard unit for marking knowledge.
The knowledge learned by Devil nobles could only be described as comical compared to Ajuka's knowledge.
And for the current Rias, Satan Ajuka's knowledge was the same.
Fortunately, learning through inheritance was much easier than it had been for Rias as the pioneer.
Even so, her progress might not necessarily keep up with Rias herself.
"I'm looking forward to it a bit."
The Rias of this world smiled.
"Don't worry, it will definitely meet your expectations."
Rias also smiled.
You have no idea how weak you are.
After taking a good rest, the two of them enjoyed a rare moment of leisure.
They soaked leisurely in the bath, washing away the fatigue from their bodies.
"It's already been half a month."
The Rias of this world murmured, "That was fast."
"The training process was painful, but... looking back now, it was a good period of time."
"As a noble, your aptitude is very good. But it's also because your status as a noble protected you too well; you haven't experienced true hardship," Rias said. "And that's exactly why you lack the mindset of a powerhouse."
"How does it feel to have the power to control your own destiny?"
"It feels great." The Rias of this world smiled. "I feel like I could easily crush that guy Riser Phenex."
"It's not just a feeling; it's already a fact."
Rias said.
Becoming a Ultimate-Class Devil isn't that easy. Riser Phenex is also someone who relied on talent to get where he is today, without actively training.
In the original story, after losing to Issei Hyoudou, he even became completely demoralized, locking himself in his room and fearing everything related to dragons.
"Then in a couple of days, I'll apply for a Rating Game and then dissolve the marriage."
The Rias of this world clenched her fist and said, "I can't fall too far behind Sona either."
Sona Sitri, the second daughter of the Sitri Family.
The eldest daughter, Serafall, became a Satan, which was equivalent to being adopted into the Leviathan line.
As the second daughter, Sona was effectively the future head of the Sitri Family.
Because of this, her parents were quite anxious and arranged a marriage for her.
Just like Riser Phenex—in fact, Sona's fiancé was even worse than Riser—she had dissolved the marriage early on through a Rating Game.
At least Riser Phenex was an adult Pure-blood Devil, and with the phenex abilities, there were few means to counter or suppress him before one became a Ultimate-class Devil.
As for Serafall, she was already very willful herself, and as a Satan, she had a great deal of autonomy; even her parents couldn't interfere with her will.
"By the way, what about the Sona of the parallel world? I remember you and Sona..." Saying this, the Rias of this world's face turned slightly red, and she then sank into the water.
"She's very cute."
Rias smiled and leaned close to her ear, saying, "Whether it's her usual straight-laced act, her time in bed, or even her expression when she's so embarrassed she's about to faint along with her sister—they're all top-tier."
"Ah, you and Lady Serafall too..."
The Rias of this world wore a dumbfounded expression.
A pair of sisters? Her parallel world self really knew how to play!
But thinking about it, Devils and humans are different after all.
The most important thing is their perspective; furthermore, there are simply too many ways for Devils to play, and physical satisfaction is actually the easiest thing to obtain.
Finally, there was the thing Pure-blood Devils valued most: offspring.
As long as the third point was resolved, everything else was not a problem at all.
"Speaking of which, it's been half a month..."
Rias sighed with emotion.
Although her sigh was very similar to the current Rias's, the latter had already heard the deep meaning hidden within it.
"Training is over. It's time we did something to relax the mind and body and bring some pleasure, isn't it?"
As Rias spoke, the other girl pursed her lips, and then her gaze became suggestive.
The Rias of this world seemed to have made up her mind; she was no longer passive but actively leaned closer.
She placed her hands on Rias's shoulders and slowly approached.
Though she was inexperienced, her movements weren't stiff. Should one say, as expected of a Devil?
Lip pressed against lip; the soft lips were like two hearts drawing close. Their heartbeats seemed to become synchronized, and they felt a certain joy from the bottom of their hearts.
"You've become quite proactive."
A few minutes later, Rias chuckled, the faint heat from her breath visible to the naked eye. Both of their fair skins were tinged with spots of blush.
"Once a woman of the Gremory Family has made up her mind, she won't regret it."
The Rias of this world said, "I wasn't sure before, but now I can be certain—I've completely fallen for you."
"Just as you said, we are completely different inside. Everything about you is attractive to me."
"So—"
"Being constantly passive isn't my style. You'd better be prepared~"
The Rias of this world revealed a beautiful, sweet smile.
