Two years passed in the blink of an eye—
In these two years, Aizen, Kisuke Urahara, Hirako Shinji, and others—a total of five people—became High-Class Devils.
In all the Rating Games, the two teams almost never exerted their full strength.
In this world, the time before the darkness arrives is a golden age, and before that golden age truly began, the experts of the three great races were still in their training stages, yet to show their potential.
The only noteworthy opponent was the person known as the Champion in the Rating Games.
Diehauser Belial.
His ability is to render the opponent's characteristics 'worthless'.
For example, in front of him, the Bael Family's Power of Destruction would turn into worthless magic Power, meaning the ability to destroy would no longer function.
If it were ice, the ice attribute would also disappear.
If it were the Red Dragon Emperor's multiplied Power, the portion of Power that was multiplied would vanish.
But obviously, this Power has its limits~
At least, Diehauser Belial's Power could not be applied to Rias.
First, the quality of her magic Power was too high; even if it were countered, it wouldn't matter, because the opponent's 'worthlessness' would be destroyed.
Then there is the characteristic of the Power itself.
Rias's Power of Destruction isn't just simple magic Power; it has already integrated concepts and is condensing into a Power.
If one had to describe it, it should be called a Fragment of Power.
Besides this champion, Diehauser Belial, Rias and Sona's two teams also encountered other teams with relatively massive Power.
For example, the teams led by Roygun Belphegor and Bedeze Abaddon.
Even though they seemed full of loopholes to Rias, they possessed massive magic Power, clearly relying on external items to boost their strength.
The King Piece—
It exponentially strengthens the holder's abilities, by tens or even hundreds of times.
If one looked closely, it was clear that Roygun Belphegor and Bedeze Abaddon had not shown any special talent in their youth, yet they rose to prominence in the Rating Games.
Obviously, it was cheating~
Although Rias also used this Power, as Rias herself grew, her King Piece gradually mutated.
If one were to take out the King Piece Rias used and give it to someone else, it could probably instantly increase the quality of their magic Power by over a thousand times.
If a Low-class Devil integrated with it, they would directly promote to the Demon King level.
If a Demon King integrated with it, they might even directly reach the Transcendent level.
And this Power has no side effects!
This was no longer just a matter of cheating; it was Rias's own achievement.
So she, Rias, did not cheat!
The names of Rias and Sona echoed throughout the Underworld.
Although there was also a lot of negative information, one must remember that they were the younger sisters of Demon Kings.
Sirzechs was one thing, but Serafall didn't care who you were; even members of the Devil Council would get a sound thrashing if she caught them.
As for those who tried to make an issue of Rias and Sona's personal strength, they were eventually proven wrong.
The team of the former 2nd rank in the Rating Game, Roygun Belphegor, collapsed the moment they faced Rias, and the entire game field was erased.
Power of Destruction of this level made all devils tremble.
One couldn't help but marvel once again that the Gremory Family had produced another monster.
Naturally, the ones with the most complicated feelings were the Bael Family.
Power of Destruction is clearly a hallmark of the Bael Family, yet it became the symbol of Gremory (laughs)~
Sona was a bit weaker, but by relying on the magical device Rias gave her, she was able to compete normally in the Rating Games.
She would occasionally take action once or twice; although her displayed strength was worlds apart from Rias's, it wasn't enough for people to criticize her.
Then, just before they were about to go independent, Aizen and Hirako Shinji had a tacitly agreed-upon Rating Game.
Rias and Sona were playing chess together, close as could be.
But as their peerages, the two sides were fighting to the death, beating each other's brains out.
The process was full of twists and turns.
At first, Hirako Shinji's side held the advantage, but after he unleashed his 'Bankai', Aizen completely saw through his abilities, and the match turned into a crushing victory for Aizen.
Mirror Flower Water Moon was utilized to its fullest in this battle, and then he was backstabbed by Ichimaru Gin.
But Aizen was prepared this time, and he eliminated Ichimaru Gin with a counter-move.
In the end, however, he lost to Kisuke Urahara, who used all sorts of strange items.
So the ultimate winners were Hirako Shinji and Kisuke Urahara's side.
Because he didn't have the Hōgyoku, Aizen had exerted his full strength in this battle.
Unfortunately, he still lost~
Consider this a small taste of defeat (laughs)~
After the decisive battle between the two teams, the groups mostly disbanded.
After Aizen, Kisuke Urahara, and Hirako Shinji became High-Class Devils, they received recognition as Kings and established their own independent teams.
Nelliel didn't belong to Aizen's team from the start; she only stood by Rias's side.
Then there was Tier Harribel, who became a High-Class Devil over these two years and established an independent team.
Finally, Grimmjow Jaegerjaquez also became a High-Class Devil and went independent.
Most of the others were Middle-Class Devils, though some have already applied to become High-Class Devils.
Instantly, Rias and Sona's teams became empty.
However, with a total of five High-Class Devils plus their reputation from the Rating Games, they still formed a massive force when gathered.
Strength, prestige, reputation... they already possessed everything.
On the basis of Rias taking over Diehauser Belial's position as Champion, she submitted a certain application to the Devil Council.
To establish a new city!
To this end, Rias applied for the Sea of Demons as her territory.
Although 'Lucifad' was the old capital and 'Lilith' is the current capital, in reality, the true center of the Underworld is the Sea of Demons.
The Sea of Demons is the largest ocean in the Underworld, and one of the few that is not man-made.
But here's the problem.
As a natural sea of the Underworld, the Sea of Demons is not blue like the Human World, but is instead filled with black mud.
That is the legendary Underworld, the filthiest place in the realm.
It is said that in ancient times, it was a giant sinkhole filled with the undying dead and black flames.
At some point, this sinkhole was filled, and the flowing black mud even gives devils a burning sensation.
And now, that area is one of the most dangerous zones in the Underworld, and its surroundings have been sealed off.
"If a new city is to be established, the Sea of Demons is indeed a good choice as the center of the Underworld, but it is far too dangerous. Is it really possible to build a city there?"
Sirzechs asked.
"Of course there's no problem."
Rias smiled and said, "I have been preparing for this for two years. It will definitely give you a big surprise."
"I see..."
Knowing that his sister had her own plans, Sirzechs made up his mind.
"I will get the Devil Council to approve your application."
One week later—
With Sirzechs acting as a guarantor, Rias successfully secured the core of the Underworld~
To this, Rias only wanted to say—
You know nothing about Power~!"
