Holy Sword Creation, Blazing Heaven Thunder Prison, and Eternal ice princess are all Sacred Gears that had wielders in the original story.
The difference is that Leo's Blazing Heaven Thunder Prison and Yukinoshita Yukino's Eternal ice princess are both god-slaying tools, unique existences. While Yuuki Asuna's Holy Sword Creation is an extremely rare Sacred Gear, as long as it's not a god-slaying tool, it's possible for multiple copies to exist.
In such a situation, it would seem that Yuuki Asuna possessing Holy Sword Creation shouldn't be surprising at all. After all, Leo already knew when he reincarnated her as a demon that her potential was not much worse than Yukinoshita Yukino's, and the Sacred Gear within her would certainly be a very powerful and rare type.
However, when Yuuki Asuna awakened her Sacred Gear and displayed the power of Holy Sword Creation, Leo was still astonished.
The reason was simply that he hadn't expected one of his reincarnated demons to be the wielder of a Sacred Gear rumored to be the natural enemy of all demonic beings.
A demon, wielding a Sacred Gear specifically effective against demons?
And it was of the holy attribute, a Sacred Gear even more potent and terrifying against demons than the light power of angels and Fallen Angels?
What do you call this? A traitor in our midst?
But it must be said, this is indeed a very suitable Sacred Gear for the "Knight" rank.
"It's clear that your future role is that of a swordswoman."
Leo smiled at Yuuki Asuna, who had opened her eyes and was staring blankly at the holy swords appearing around her.
"With the speed characteristic granted by the 'Knight' rank, if you can properly unleash the power of these holy swords, the threat you pose to your own kind might even surpass mine and Yukino's."
Although it's a Sacred Gear specifically effective against demons, this doesn't mean Yuuki Asuna is useless.
Demons also engage in infighting, and when they do, they can be more ferocious than any other race. The Underworld once saw a terrible internal struggle between the Old Satan Faction and the Reformist Faction, where many demons perished. Even now, many historical issues remain, causing incidents to erupt in the Underworld from time to time.
In the future, the Old Satan Faction will become a major enemy of the current Underworld. At that time, Yuuki Asuna will certainly shine brightly and become a highly anticipated new demon.
And even without considering internal conflicts, Yuuki Asuna's power will have its uses.
You should know that currently, the most popular competition in the Underworld is the Rating Game.
It's currently the most highly regarded competitive match. From the Demon Lords down to the common populace, all demons are loyal enthusiasts of this competition.
After many pure-blooded families among the Seventy-Two Pillars died out, the current Demon Lord Beelzebub developed devil chess pieces to salvage the dwindling demon population, and this competition began to gain popularity.
The main participants in the competition are demons who serve as "Kings." They can lead their Retainer teams to battle against Retainer teams led by other "Kings," competing under different rules to determine victory and defeat, showcasing their own and their Retainers' strength to the higher-ups and the general public, and demonstrating how to use the rules to achieve victory.
Today, the Rating Game has become one of the most important ways to determine a demon's status. A demon's performance in the Rating Game will directly influence the higher-ups' evaluation of themselves and their Retainers. If they perform well and receive a high evaluation, it's not uncommon for them to receive a promotion in rank or a noble title afterwards.
Historically, countless demons have distinguished themselves in Rating Games, rising to prominence. And countless demons have used this to advance, from Mid-level Demon to High-Class Devil, and then from High-Class Demon to Highest-level Demon, thereby gaining the opportunity to recruit Retainers and debut as a "King," just like their master.
Therefore, participating in the Rating Game has become an aspiring future for new generation demons. Even High-Class Devil who are already "Kings" want to use this opportunity to climb higher and become Highest-level Demon, the highest rank below the Demon Lords.
For example, Sona Sitri has the intention to participate in the Rating Game, wanting to achieve one of her dreams through it. Sona Sitri's childhood friend from the Gremory family also has the desire to dominate the Rating Game.
There are only two entry requirements for the Rating Game: one is that it must be a Retainer team led by a "King," and the other is that they must be adults.
Leo, Sona Sitri, and Rias Gremory will all turn eighteen this year. Soon, they will be able to debut as new generation demons, and then they can begin preparing to participate in the Rating Game.
Leo naturally also has the idea of participating in the Rating Game, even if he knows that if the original story's development continues, the entire world will likely fall into chaos soon, and it's uncertain whether the Rating Game can proceed smoothly. However, many descendants of pure-blooded demon families are about to debut among this generation's new demons, and a debut battle for new generation demons will be held at that time, which he will most likely need to participate in.
And whether it's the Rating Game or the debut battle, Yuuki Asuna, who possesses a holy attribute Sacred Gear that counters demons, will become a powerful trump card.
At that time, for Leo's opponents, Yuuki Asuna's threat might not necessarily be lower than his and Yukinoshita Yukino's, the two god-slaying tool wielders.
It's just... "I also have to rack my brain to figure out how to arrange you properly."
Leo said this, causing Yukinoshita Yukino and Yuuki Asuna to pause slightly.
"Is there a problem?"
Yukinoshita Yukino asked on behalf of Yuuki Asuna.
"A not-so-small problem," Leo didn't hide it, saying, "The Erigor Family is a very traditional demon lineage. The abilities of family members are basically developed towards magic power, and almost no one develops towards close combat."
"You and I are both traditional demons based on magic power, so we can easily find the relevant knowledge we need from the family's collection of books to learn and utilize magic power."
"Even for Sacred Gears, there are some relevant records in the family's collection of books, even though family members throughout history have indeed encountered many Sacred Gear Holders."
"But in terms of swordsmanship and sword techniques, I estimate that the family's collection of books has very little relevant knowledge."
In other words, Yuuki Asuna can learn to use magic power here, and she can also learn to use Sacred Gears here. However, her weapon is a sword, and besides the techniques for using Sacred Gears, sword-wielding techniques are also essential.
The family's collection of books can teach her how to activate the power of her Sacred Gear to create holy swords of different attributes and abilities, but it cannot teach her how to swing a sword or how to execute clever close-combat techniques in battle against enemies. These are things that need to be learned separately.
Neither Leo nor Yukinoshita Yukino have much accomplishment in close combat, let alone swordsmanship.
Yukinoshita Yukino is still better off; at least she has mastered some Aikido techniques. Leo, on the other hand, has truly not mastered many close-combat abilities.
Don't let his seemingly effortless performance in the previous battle with Sharon deceive you. Even when the opponent unleashed a continuous barrage of attacks, he could easily evade them by relying on his movement techniques, but this wasn't purely due to close-combat prowess; it was with the aid of magic power.
The Erigor Family's magic power is extremely adept at detection. Leo had spread his magic power out at the time, discerning all of Sharon's movements, which allowed him to evade with ease.
But that was only temporary. If Sharon had launched a surprise attack, even if he could detect her movements, his body's reaction wouldn't keep up.
This is why Leo later had to use magic power to construct a barrier of magic power to block Sharon's attacks, then switch from defense to offense, violently bombarding her with magic power.
In summary, Leo is truly not good at close combat, even though a demon's physical abilities far exceed those of ordinary humans.
"If it's just learning swordsmanship, it shouldn't be too difficult, right?"
Yukinoshita Yukino frowned, and for a moment, she even entertained the thought of using the Yukinoshita Family's resources to find some master swordsmen to train Yuuki Asuna.
"Indeed, human swordsmanship isn't entirely useless, but it's ultimately something suitable for humans, not necessarily for demons." Leo saw through Yukinoshita Yukino's thoughts, pondered for a moment, and finally said, "At this point, it's better to seek external help; there's no need to insist on solving it ourselves."
"Seek external help?" Yukinoshita Yukino thought of something and said, "President Sona?"
"Yes." Leo nodded and said, "The Sitri Family has always been my supporter and sponsor behind the scenes, and their family has never died out, so they should be able to solve this problem."
The Erigor Family died out before the birth of devil chess pieces, so no one had ever become a "King" leading a Retainer team, and there was no need to consider the development of Retainers.
The Sitri Family is different. Since the birth of devil chess pieces, countless "Kings" have led teams from their family. They also have "Castle," "Knight," and "Pawn" units that require close-combat abilities, so they must have collected a lot of relevant knowledge.
Also, the demon higher-ups of the Underworld should now be paying more attention and concern to him because of the report Sona Sitri brought back last time, right?
If he made a request to them, hoping for some support in this area, he would most likely get his wish.
It's just some knowledge about close-combat techniques, not a family secret like special magic power application methods. There's no need to cherish it or be reluctant to share it.
Demons value magic power the most; knowledge in other areas is truly not given much importance by them. Many arrogant demons even believe that close combat is only necessary for crude subordinates, and true demons should fight with magic power.
"Without further ado, I'll contact Sona right away." Leo stood up and said, "Yukino, take Asuna on a tour of the estate."
Yukinoshita Yukino nodded, accepting the task.
