Chapter 167: The Twin-Tailed Girl is the Ancestor, the First Gremory
Under the night sky, at the house where Rias lived, all of her servants were present.
The reason for their gathering and the serious atmosphere was due to the presence of a silver-haired woman dressed in a maid outfit.
Though she wore a maid uniform, this silver-haired woman was Rias's sister-in-law—her brother's wife, Grayfia Lucifuge.
Her sudden visit had truly startled Rias.
Fortunately, Rias had considered the possibility of the Gremory family suddenly teleporting over, so after the destroyed Occult Research Club was restored, she hadn't reinstated the magic circle.
Similarly, the teleportation magic circle originally present at the villa provided for that guy had also been removed by her.
Only the magic circle at her current residence remained.
Now, with Grayfia's sudden arrival, it was clear she had noticed something and was here to question her, which made Rias very nervous.
Suddenly, Grayfia narrowed her eyes and stared intently at Akeno, as if trying to discern something from her.
Although Akeno appeared no different from usual and was doing her best to suppress her aura, making it impossible to sense her as a High-class Devil, Rias was still afraid something might be discovered.
"Rias, in a few days, the leaders of the three factions will hold a meeting in this city."
"Huh? What?"
Rias's face changed color.
For such a sudden meeting to be held in this city, it couldn't be without reason. Had they discovered something?
How much had they specifically noticed?
"Why choose my location?"
"Why? Don't you know yourself?"
Grayfia retorted.
Seeing Rias fall silent, she tossed out a photograph, causing Rias's expression to shift slightly.
"Recently, you've mobilized a lot of the Gremory family's resources to conceal information about this person. Shouldn't you explain something?"
"I don't know."
Rias played dumb.
"Never mind, we'll discuss his matter later. You also don't need to worry about the angels coming to demand accountability. The three-faction leaders' meeting doesn't have the leisure to discuss trivial matters."
This made Rias breathe a sigh of relief. It seemed Grayfia only thought he was involved in the Church's holy relic incident.
Afterward, Rias became conflicted.
How should she reveal the existence of the otherworld invasion without drawing investigation toward him?
This matter was extremely important, but she couldn't expose him at the moment.
So, she was troubled, and Sona was equally troubled, unsure how to disclose it.
"What kind of meeting will be held here?"
Though she felt asking was pointless, Rias still tentatively inquired, only to receive a silent response.
"The meeting is in three days. As the future head of the Gremory family, please make preparations and arrangements."
With these words, Grayfia prepared to leave.
"By the way, Grayfia, I saw someone like this a few days ago. She looked a bit younger than me, also had red hair, was female, and wore twin tails. She seemed like a member of the Gremory family. Do you know who she is?"
Rias immediately used this topic to detain her, while her mind was still pondering how to reveal the otherworld invasion.
However, she noticed that after saying this, Grayfia's reaction was somewhat unexpected—it seemed Grayfia knew of such a person.
"You've met that one? She actually came to the human world too."
Saying this, Grayfia also massaged her temples with a headache.
"Who is she?"
Grayfia didn't answer, but it wasn't that she refused to.
Seeing this, Rias's several servants behind her seemed to realize something and voluntarily excused themselves.
"Can you tell me now?"
"That one is indeed a member of the Gremory family, and one could say her Gremory bloodline is even purer than yours, Rias."
This left Rias stunned.
"That one can be said to be one hundred percent pure Gremory blood, without any other devil's lineage mixed in."
"How is that possible!"
How could there be such a person in the Gremory family? A one hundred percent pure Gremory bloodline—such a person simply didn't exist.
No, there was one—the Gremory ancestor at the Origin.
Wait, the Gremory at the Origin?
It couldn't be, right? After all, the first ancestor at the Origin was said to be dead.
Could it be a resurrection?
Ugh, if that one has been revived, things are really going to get messy.
"Y-you can't mean the Ancestor, can you?"
"Yes, the origin of the Gremory family."
"B-but wasn't it said that the Ancestor had passed away?"
So they've truly been revived now?
"That was just the official story. After all, if the origin devil were known to be alive, it would easily draw all sorts of trouble. That's why they've spent most of their time in hibernation for so long. And the day they woke up was that day!"
That day, he summoned the Ancestor and then kicked them right back.
Ugh!
Rias felt like fainting.
Suddenly, Rias sharply realized something.
How could he not recognize the Ancestor?
Perhaps the Ancestor's current appearance differs from how they looked in the past. Based on his description, the Ancestor now seems to be about the same size as Asia, so maybe that's why he didn't recognize them.
The Ancestor from 730 years ago was probably a mature and stunning woman.
"Grayfia."
"Is there still something?"
"Do you think there might be others—no, never mind, it's nothing."
Rias had already thought of a way to reveal the matter of the other world.
The corpses of those otherworldly mechanical lifeforms that were killed hadn't disappeared. She planned to lure the leaders of the three factions to discover these remains in a certain location on the day of the meeting.
...
Late at night, three figures were swiftly running through the quiet town.
To be precise, two were running while one was being carried, as that person still appeared to be unconscious.
"Damn it, what exactly is this thing!"
"No matter how much we cut it, it won't die. It regenerates—what kind of monstrous metal creature is this?"
"There's an open area ahead. Lure it there, then destroy the entire area. I refuse to believe it still won't die!"
This thing had attacked them not long after they discovered the girl. They thought it was dead after being blasted to pieces, but it reappeared as soon as they entered this city.
Worried about damaging the surrounding buildings, the two hadn't been able to go all out.
Soon, they would use even greater destructive power to turn it into dust—surely it couldn't regenerate from that.
