Rias attempted to use the power of 'Return' on herself, but unfortunately, she failed.
Was it because of the characteristics of her magic power?
Rias thought.
Generally speaking, the healing method of Return begins with restoring Spiritual Pressure.
That is to say, first, Spiritual Pressure is channeled into the injured person's body;
The recovered internal Spiritual Pressure and the practitioner's external Spiritual Pressure work together to restore the spiritual body. It can be said this is an ability specialized in healing soul injuries.
However, this does not mean Return cannot heal physical injuries.
Return restores one's own soul form, thereby allowing the body to return to its original state under the soul's guidance. This is also possible.
If she could master spiritual power, she could effectively protect her own soul and cultivate power related to the soul.
In the world of High School DxD, there are places like Hell and the Land of Bliss. Under the premise of the world's rules, destroying a soul requires special means, but it is not impossible.
If she possessed spiritual power, not to mention the issue of healing, even if she accidentally died, she would have the ability to transcend the rules and revive on the spot.
"Spiritual power isn't urgent; there are still many subjects to study..."
Although she unintentionally reached the second stage of the 'Fusion Equation,' it was merely reaching it.
What Rias wanted was true 'mastery'!
Physical training, combat experience, transformation of energy essence, research on spirits, observing her own Fusion Equation to achieve complete control, and so on.
There were still many different matters. Especially after Rias's experiments, she discovered that a Zanpakutō does not have only one form of release.
Just like Kisuke Urahara's Benihime, it can possess various forms of attack.
In other words, even the Shikai of a Zanpakutō has much room for development.
In particular, Rias did not name her Zanpakutō after the Fusion Equation, but after her unique combat method, the Hakai Hōteishiki!
For the Hakai Hōteishiki, the Fusion Equation is merely a core part of it.
In summary, although she indirectly achieved a stable 'Fusion Equation Second Stage' through the Zanpakutō, she actually became busier.
Inside the Arena, Rias voluntarily'surrendered' and exited, sending the Soul Reaper Piece to Unohana Retsu.
Then, in the main world, she began recreating her Zanpakutō.
Taking even less time than in the Arena and achieving a more perfect result, Rias quickly created a new Shikai method.
The Hakai Hōteishiki has nine techniques, many of which Rias could achieve herself through Magic Formulas.
But undoubtedly, using the Zanpakutō was easier and more convenient.
Moreover, using the Zanpakutō was equivalent to automatic control, while using it herself was manual control.
Using the Zanpakutō also did not hinder Rias from manually using Magic Formulas, which could be considered an additional combat method.
As for Bankai, she also attempted it, but Rias judged that her Bankai was not yet complete.
This was not strange because the release of a Zanpakutō is essentially according to the Soul Reaper's will.
An incomplete Bankai is not because the Zanpakutō is unfinished, but because she has not yet perfected the Zanpakutō.
These are two similar, yet different concepts.
For example, Yamamoto Genryūsai Shigekuni's Zanpakutō: its Bankai underwent tremendous changes between a thousand years ago and the present.
This was because he developed the Zanpakutō to a deeper level.
The existence of the Zanpakutō undoubtedly could reduce Rias's research time.
Having a finished product and a pre-developed concept are two completely different levels of difficulty.

Time passed—
In Rias's research, three months quickly went by.
During these three months, Rias's subjects were resolved one by one, but they actually accumulated more and more.
The more one understands, the more subjects are born. This is the natural order of the world.
Rias was so busy that she practically spent all day immersed in the library, which greatly worried her family.
"Little Rias has been in the library for three months. What should we do if she continues like this?"
Rias's mother, Venelana, worried.
"Everyone has their own thoughts; we cannot force them."
"And Little Rias is also trying to improve her strength. It's not something to be ashamed of."
Zeoticus pretended not to care, but a similar worry was revealed in his eyes.
Venelana's hair is brown; she is from the Bael Family.
The source of Sirzechs and Rias's Power of Destruction is Venelana, while their hair color is inherited from the Gremory side.
That is, from Rias's father, the current head of the Gremory Family, Zeoticus Gremory.
"But, but!!"
Venelana leaned close to Zeoticus's face, on the verge of tears, and said, "That child is just too much of a shut-in!!"
"Don't say it's okay to be a bit of a shut-in now; what if she stays this way in the future?"
"This..." Zeoticus was also left speechless.
After Sirzechs inherits the position of Lucifer, the Gremory Family will inevitably be inherited by Rias.
However, from the looks of it now, Rias has no such interest.
Continuing like this would obviously lead to major problems!!
"What on earth should we do?"
Venelana murmured.
"How about asking Little Sirzechs to think of a way?"
Zeoticus said, "Or perhaps Little Rias's sister-in-law, Grayfia?"
"With her abilities, she might be able to draw Rias out."
"Why don't you do it?" Venelana puffed out her cheeks.
"Don't tease me, dear."
Zeoticus said with a bitter smile, "You know as well as I do, I seemed to have ruined one of Little Rias's important experiments a month ago and got dragged to the training ground."
"I didn't think much of it at first, but I ended up getting thoroughly beaten up."
"A three-year-old Ultimate-Class Devil..." Venelana sighed. "Apart from the characteristics of her magic power being slightly lacking, she might even be more outstanding than Sirzechs was back then."
Sirzechs's magic power was naturally abnormal, while Rias's is normal Power of Destruction, except it awakened at birth.
The so-called magic power awakening is a characteristic of pure-blooded High-Class Devils.
Each family has its own characteristics, but that is only superficial.
Only by truly excavating it and causing the magic power to awaken can the magic power characteristics of a pure-blooded devil be maximized.
Sirzechs and Rias awakened naturally, but Sirzechs's magic power was more abnormal.
Sirzechs's training was more about normal cultivation, while Rias would likely forge her own path.
This is what Venelana and Zeoticus, and even Sirzechs, believed.
However, they did not want to hinder Rias from becoming stronger. The problem was that single-mindedly pursuing power while neglecting the family bonds most valued by the Gremorys could lead to issues.
They still remembered Grayfia's brother, Euclid Lucifuge.
Although Euclid hasn't done anything yet, they had a premonition it was only a matter of time.
Although they had confidence in Rias, the couple did not want to fail in their parenting.
Devils are relatively heartless, but that does not include the Gremorys.
Even in a family of complete villains, a good person can always be born.
Just like how DIO was a villain, but his little bread Giorno was not.
"Can we only rely on Little Sirzechs?"
Zeoticus sighed and said, "Our son always does things so perfectly. If possible, I really don't want to add extra pressure on him."
"Who knows, maybe Little Sirzechs enjoys it~"
Venelana laughed.
Having children who are all Transcendents among devils, in a sense, this couple is the strongest.
