Wandering within the Dimensional Gap, the Great Red not only had to stop people within the DXD World from seeking death but also prevent invasions from entities of Other Worlds.
Not just wandering in the Dimensional Gap, the Great Red's 'dream' power enveloped the Dimensional Gap near DXD to seal off passages to Other Worlds and prevent others from discovering them.
Generally speaking, without protection, any existence that comes to the Dimensional Gap will quickly perish.
In other words, those that manage to drift in are usually not trash.
Occasionally, continents shattered by powerful beings drift in, only to be slowly worn away until they finally turn into nothingness.
The power of dream not only protects this place, but similarly, any drifters from Other Worlds—whether living beings or dangerous items—will be directly sent away by the power of dream.
However, after the Great Red entered the world, she gave up on protecting it in just two years.
Especially since the Great Red was merely born within the Dimensional Gap; this didn't mean she had to protect the world, as she didn't have that responsibility.
She only maintained peace between worlds because she found the life within them interesting while she was wandering.
The Dimensional Gap was indeed her home, however—
The Dimensional Gap is vast; the corner where the DXD World resides is just a small part of it.
Especially after seeing Rias's potential and dreams, she had become obsessed with Rias.
After Rias created the Crimson World, the Great Red simply moved in and actively merged with the world.
As mentioned before, the Crimson butterflies are connected to Rias's root.
The Crimson World is the source that nurtures the Crimson butterflies; by merging into it, the Great Red essentially became Rias's peerage of her own accord.
To the Great Red, the Crimson World was filled with 'gems' everywhere.
Meanwhile, the outside world was full of weeds and kindling that were hard to ignite; finding a beautiful dream there was harder than finding gold in a pile of dung.
While Issei Hyoudou's dream was a bit eccentric, its purity was extremely high, which was one of the reasons he could attract the Great Red after his death to help reconstruct his body.
Of course, not all gems are the same.
For example, Sairaorg Bael from the original work was undoubtedly a tough guy, yet he lost to Issei Hyoudou.
This time, it was a case of manly strength losing to the power of a pervert~
Back to the topic, the Crimson butterflies are special life forms with very close ties to the world and Rias, so they basically don't have issues with their state of mind.
Each Crimson Butterfly is both part of the whole and a unique individual.
At the same time, it is a truly ideal society.
Because of this, the Great Red decided to become a Crimson Dragon.
Without the protection of the Great Red's power, strange things from the outside began to drift in continuously.
In a corner of the Underworld, Rias had already spotted the creature before her.
It was a dragon, a massive dragon.
A green dragon.
Strange as it may sound, this dragon... was a bit plump.
Its wings were black, and compared to its body, they looked more like devil wings.
"Hiss, this is the first time I've seen such a fat dragon."
Rias couldn't help but exclaim.
Under Rias's astonished gaze, the green dragon opened its eyes.
A massive sword was plunged into its body, and Rias could feel a vast amount of divine power coming from the blade.
Though dragons are majestic, its 'interesting' physique really made Rias want to laugh.
In fact, the Great Red's true form wasn't much different, just far more majestic.
Western dragons are basically of the evil attribute, synonymous with demons; it's rare to find a dragon with a holy life form.
"Human?"
After a momentary daze, the dragon quickly dismissed its own judgment.
"No... you don't seem human. On the contrary, you give off a familiar aura... Are you of the same race?"
The big fat dragon looked at Rias curiously.
"Sort of."
Rias shrugged.
Although the dragon before her was plump and its life form didn't feel holy, it was undoubtedly a carbon-based life form.
However, its power was not weak.
If compared to this world's system, it would be at the Heavenly Dragon level, which is a Transcendent among devils.
But—
The dragon Rias referred to was completely different from this one.
Rias could no longer be considered a carbon-based life form; every drop of her blood could briefly evolve into a dragon.
In terms of this manifestation, Rias was very similar to the Dragon Lord of Little Garden.
But in reality, this method wasn't essentially about splitting spiritual authority, but rather the true essence of the paths of 'create' and 'life'.
Her true body essentially belonged to a higher-dimensional existence.
She was both the pure-blooded dragon of nothingness and the invisible Tree of Life System.
From an outward perspective, when a carbon-based life form dies, it's dead.
But for Rias, even if her physical body was destroyed and her soul perished, she could still easily be resurrected.
"My name is Rias Gremory. I was originally a devil, but later I ascended and created the Tree of Life System. I suppose I'm a pure-blooded Dragon Race, a high-ranking existence among dragons~"
Rias asked, "And you?"
"Can something like race even be changed!?"
The fat dragon was a bit surprised, but still responded to the 'compatriot' before it, saying, "I am Tohru, from the Chaos Faction, daughter of the Emperor of Demise."
The Maid Dragon who shares the same name as Thor the God of Thunder?
Rias remembered this dragon's origin.
It had to be said that it was quite interesting; the Thor of this world had a public combat power ranked sixth among the world's top ten experts.
And this Maid Dragon probably wasn't bad either.
"Enough small talk, let me pull out this Divine Sword first."
Rias chuckled and extended a finger.
With a flick of her finger and Rias's will, the Divine Sword flew up.
After recording the power and concepts within the Divine Sword, it gradually faded and then vanished.
This Divine Sword was originally a conceptual blade; after losing its target, it would disappear.
Because the true form of this Divine Sword was still in the hands of that 'God' from the Other World.
"Thank you..."
Tohru fell silent for a moment and then spoke.
"Can you shrink a bit? I'm not used to communicating with dragons of such massive size."
Rias said.
"I can."
Tohru hesitated for a moment, then transformed into a blonde human form.
With horns on her head and a green tail visible, she also gave off a bit of a silly vibe.
But her figure was great~
With a'snap', Rias snapped her fingers, and the two of them transported to the Lords Mansion.
Handing Tohru a bottle of cola, Rias also unscrewed one and gulped it down.
Tohru glanced at Rias, then at the cola in front of her, and followed Rias's lead, gulping it down.
"So refreshing!"
Tohru wiped the corner of her mouth, her face full of satisfaction.
Tohru wasn't worried about poison; after all, she was a dragon.
Besides, if Rias had bad intentions toward Tohru, she wouldn't have needed to pull out the Divine Sword at all.
That conceptual sword had already pinned Tohru down; without outside intervention, Tohru would have been killed by the power contained within it.
Having one's life force gradually drain away... that feeling is truly very lonely~
"How did you come to this world?"
Rias asked curiously.
