Since Rem had already been afflicted by the curse, Ren Kurose could roughly determine what point in the timeline her world had reached.
Rem being cursed and gradually weakening to death could only mean the Roswaal Mansion arc.
More specifically— this was already the fourth loop.
Before this, the transmigrator Subaru Natsuki had already died three times.
Everything had repeated three times, making this the fourth attempt.
However, during the third loop, Subaru had been killed by Rem and Ram, leaving him somewhat disheartened.
So this time, Subaru had remained inside the Forbidden Library.
Without Subaru accompanying her, Rem had no choice but to go out alone to purchase supplies.
As a result, she was ambushed by mabeasts and cursed.
During the first loop, it had been Subaru who took Rem’s place and died from the curse instead.
“There is actually another way.”
His voice once again sounded inside Rem’s mind.
“What way?”
“Kill Subaru Natsuki.”
“Just as I thought!
Was Subaru the one who cursed Rem?
He really is a member of the Witch Cult!”
Rem was stunned when she heard this.
She didn’t ask why He knew Subaru Natsuki’s name.
In her eyes, He was a supreme existence, so knowing something like that was hardly surprising.
What shocked Rem was that this really did seem to have something to do with the servant who had suddenly appeared at Roswaal’s mansion.
At this point in the timeline, Rem’s impression of Subaru was far from favorable.
A person reeking of the Witch’s scent had suddenly appeared inside Roswaal’s mansion.
Naturally, that alone had made Rem and the others extremely wary of him.
To them, neither Witches nor the Witch Cult were anything good.
So when Rem heard this solution, she barely hesitated before preparing to act.
“It seems you’ve already made your decision.”
“Yes.
Rem will kill Subaru Natsuki.”
Rem’s response was firm.
“He is an enemy.
He must be a member of the Witch Cult.
Only by doing this can Rem survive!”
Ren Kurose didn’t bother explaining Subaru’s situation to her.
Instead, he merely said,
“I wish you success.”
After that, Ren Kurose concealed himself completely and vanished without a trace.
Only the three-petaled flame mark on Rem’s arm remained as proof that He had ever appeared.
He had already communicated with Rem for quite some time.
So Ren Kurose temporarily shifted his attention back to Chaldea.
Although Rem hadn’t chosen to use his power to fight poison with poison, he had at least given her another method of dealing with the curse.
For Rem, this summoning had still been extremely helpful.
…
After his brief nap, Ren Kurose opened his eyes and stretched his body.
“This body really does feel much better.”
Ren Kurose muttered to himself.
The manifestation he had projected into Rem’s world had only been a mass of flames.
It was nowhere near as comfortable as this human-shaped body.
“Ritsuka, I’m heading out.”
Ren Kurose called out to Gudako, who was currently undergoing physical training, before preparing to leave.
Gudako immediately looked at him with envy.
“Huh?!
That’s so unfair!
It’s bad enough that you won’t train with me, but you’re even slacking off and sleeping while I’m working out!
Waaah, I’m so miserable!”
Ren Kurose smiled.
“Can’t be helped.
Different people have different constitutions.”
Gudako: “…”
Despite complaining, Gudako had no intention of giving up.
Even after Ren Kurose left, she continued training.
Seeing that, Ren Kurose could only sigh inwardly.
As expected of humanity’s last Master.
That title certainly carried some weight.
Ren Kurose returned to his room.
However, elsewhere in Chaldea, one particular man was currently overwhelmed with shock.
Romani.
Ever since he had used Solomon’s ring to hear His full name clearly, Romani had begun searching for information.
And surprisingly— he really did find some.
That was precisely why Romani was now so shaken.
Inside his room, Romani stared at the information he had gathered before collapsing weakly into his chair.
“A…
deity…”
Unlike the Greek, Indian, and Chinese pantheons, which genuinely existed within this world, the Cthulhu Mythos was supposedly nothing more than fiction written in novels.
That was why Romani had initially searched for a long time without finding any information related to Yomagn’tho.
It wasn’t until he came across the writings of Howard Phillips Lovecraft that he began noticing certain similarities.
those indescribable entities could cause people’s minds to collapse merely through exposure.
In severe cases, victims could lose consciousness or even die.
Romani had sensed similar effects from Yomagn’tho Ren Kurose.
That realization led him to continue investigating along the trail of Lovecraft’s works and related writings.
Eventually, within the later work The Extraterrestrial Banquet, he finally found the name—
Yomagn’tho.
Finding information about Him left Romani deeply shaken.
If all of this was real, then what exactly was Howard Phillips Lovecraft?
Was he some kind of representative of these deities on Earth?
Truthfully, under normal circumstances, even characters originating from fictional stories could be summoned as Servants.
There were examples such as Oberon and Nemo.
But in those cases, everyone at least understood that they came from stories and legends.
This was different.
An actual Outer God had appeared.
An entire mythology that was supposedly fictional now seemed to have been proven real by the existence of Yomagn’tho Ren Kurose.
How could Romani possibly remain calm?
Worse still—
He fed upon celestial bodies.
Romani was terrified.
Terrified that He might take an interest in Earth.
If that happened, the entire planet would be in danger.
Perhaps only the gods of Earth itself could stop Him.
At least, that was what Romani believed.
In reality, the Cthulhu-related existences within the Type-Moon setting operated on such an absurdly high level that even the divine pantheons of the Solar System might not necessarily be enough.
“What a disastrous time…”
Romani gave a bitter smile and shook his head.
“Humanity is facing an enormous crisis, and now the Earth itself may be in danger too.”
However, his expression soon became serious again.
The situation might not actually be quite that hopeless.
Now that he knew more about Him, Romani had also learned that Outer Gods couldn’t casually descend upon Earth.
Especially not in the form of a Servant.
The fact that Yomagn’tho Ren Kurose had appeared on Earth through a Servant vessel already implied quite a lot.
Otherwise, Gaia would never have permitted His presence.
There had probably been some kind of agreement.
Romani could only try to think positively.
Moreover, He did not appear hostile at present.
He had even formed a contract with Ritsuka Fujimaru.
That allowed Romani to relax— if only slightly.
Of course…
if Romani knew that Yog-Sothoth would eventually show up as well, there was no telling what kind of expression he would make.
