"..."
Tatsumaki: "I... um..."
"Ding~"
"Rias Gremory has requested to travel to your world. Do you accept?"
Before she could finish speaking, Rias clicked the application.
Because Rias really liked Tatsumaki's sexy lolita appearance, she had specifically looked into her information.
At this moment, Rias also remembered that Tatsumaki seemed to have been abducted into some organization as a child and subjected to inhumane research.
Thinking of Tatsumaki's tsundere personality, Rias didn't wait for her to finish and directly clicked the application to enter her world.
After waiting about ten seconds, Rias's figure vanished from the Underworld and arrived in another world.
Surrounding her were walls forged from steel, and before her stood Tatsumaki, dressed in tattered clothes.
It gave the impression of a prison uniform.
Even though her figure hadn't changed at all, it didn't give off the future's alluring vibe at all; instead, she was truly a lost little girl.
"Hello, I'm Rias."
Rias raised her hand slightly.
"A... a child?"
Tatsumaki couldn't help but murmur.
"Well... although I am indeed quite young."
Rias didn't argue and instead greeted her softly.
Red lights began flashing around them, accompanied by a piercing sound.
This was because the room was under surveillance; obviously, one couldn't expect any humanitarian thoughts from such a shady organization.
In fact, children like Tatsumaki were merely expendable research materials to them.
"Let me... sense a bit..."
Rias spread her hands, and a three-dimensional square magic array composed of various patterns in her mind transformed, rapidly constructing a complete view of everything within a kilometer radius.
It was even more exaggerated and detailed than a god's-eye view; everything was laid out clearly.
"Destruction Formula Six: Absolute Destruction Barrier."
Instantly, a red light blossomed.
Destructive magic Power formed a circle, enveloping the surroundings.
By the time Tatsumaki reacted, everything around them had vanished.
Only hundreds of children remained, along with a kilometer-deep crater.
"It seems there are no strong individuals here capable of withstanding my Power."
Rias smiled slightly.
"So strong..."
Tatsumaki stared at Rias in astonishment.
"You look like you haven't had a full meal in a long time."
Rias looked at Tatsumaki's emaciated appearance and asked, "Would you like to come to my house as a guest?"
Tatsumaki thought for a moment, and her stomach suddenly rumbled.
This organization conducted experiments on superpowers, technology, and Monsters. Because Tatsumaki's superpowers were too strong, aside from equipment targeting superpowers, she had to be kept hungry to suppress her.
So, she hadn't eaten a full meal in a very long time.
Perhaps this was related to why Tatsumaki maintained this physique in the future.
"Um..."
Hearing her stomach rumble, Tatsumaki couldn't help but blush.
"Let's go."
Rias smiled, first using her sensing ability to locate a city, then using Heavenly Transfer to send the other children there.
Going to this extent was already going above and beyond; after all, saving them was just incidental.
Anyway, aside from these 'test subjects,' everything else had been destroyed by Rias.
Returning to the Underworld, Rias invited Tatsumaki into her world.
This time, Tatsumaki responded quickly.
Having the Gremory Family maids bring out the food, Rias sat to the side, focusing her attention on the Chat Group.
After the newcomers joined, the Chat Group had become much livelier.
Jibril: "Speaking of which, what are the newcomers' worlds like?"
"Tatsumaki's world is a human world, but there exist beings called Monsters. Some are born as Monsters, some are human creations that turned into Monsters, and others are humans who transformed into Monsters. In short, there are all kinds, and most non-human existences are called Monsters."
"These Monsters vary in strength; the strongest can destroy planets with a full-Power strike, while the weakest might not even beat an ordinary human. Most Monsters harbor strong hostility towards humans."
Rias: "By the way, it seems there are also gods, but they're probably just lowlifes~"
"@Hinata Hyuga, her world is also a human world, one perpetually shrouded in war and conspiracy. People there with supernatural abilities are called Ninjas."
"There are five great nations, with Konoha being the strongest. From my perspective, these villages, especially Konoha, are fundamentally no different from pyramid schemes."
"The strongest are aliens, the Ōtsutsuki Clan, considered the origin of chakra."
"But even the strongest don't reach planet-busting level; they're still one or two major tiers below you, at most comparable to me when I first joined the group, though their methods are still far inferior."
When Rias first joined the group, she played around with Unohana Retsu. Actually, at that time, she was just experimenting with her Formula, not fighting with the intent to win.
If she had truly fought to win, even though her Formula wasn't perfected back then, she still had many methods to defeat Unohana Retsu, without needing to use: Formula Seven: Heavy Particle Destruction Bullet.
Rias surpassed the Ōtsutsuki's hacks in three years; one could say the Ōtsutsuki lived thousands of years in vain, with nothing particularly noteworthy.
At most, their diverse ninjutsu might be useful for developing magical properties.
"@Theresia van Astrea's world is a traditional Other World, with various Demi-human Races, Witches, Sword Saints, etc. The strongest probably don't reach your level either, but that world has a special Power called Blessings."
"It seems to be a favor granted by the world, bestowing special blessed Power, though it's likely useless in other worlds."
"As for the Witches' Power, it's an interesting ability. The Return by Death granted by Satella can return the world to a time before death occurs. The characteristic of this ability is that after death, events and emotions experienced within a certain time by oneself and those around her are reset, with only herself remembering."
"But that ability is probably only usable in its native world; whether it can affect someone of your level is also unknown."
Rias summarized.
Jibril: "@Rias Gremory, isn't that interesting?"
Rias: "You mean the Blessings and Power?"
"Mhm~"
Jibril: "I really want to study what the essence of those Powers is."
"Just thinking about that brand-new system and Power, I'm already getting so excited!!"
"But right now, fighting the Dragon-kin is definitely more important. This time, I must chop off that lizard's head!"
"Um..." Teresia: "Everyone in the group is from different Other Worlds? That sounds very interesting."
Hinata Hyuga: "Hello everyone, I'm Hinata Hyuga, three years old."
"Ah, I forgot to introduce myself."
Theresia van Astrea: "My name is Theresia van Astrea, from the 'Sword Saint' Astrea Lineage, ten years old."
Has this group turned into a kindergarten?
