"Hahahahaha! Excellent, excellent! I, Remilia, have finally become a Primogenitor! Next, I shall begin the second phase of my plan to make the Scarlet Devil Mansion rule this world… Hehe, first I'll annex this artificial island into my country!"
"Hehehe… Hmm? Wait! Ren, why are you making that face!?"
The moment she emerged from the sphere, Remilia immediately began bragging.
Hands on hips, acting like she was the greatest existence in the world—classic Scarlet sister behavior.
But she completely ignored Ren's complicated expression.
When she finally noticed, she frowned.
Something was wrong. Ren wasn't reacting according to her expectations.
He should be shocked by her power.
Even if not shocked, he should at least feel some pride. After all, she was his personally developed pet!
Sure, she knew Ophis existed, but Ren probably didn't factor in Gungnir's "one-four-zero" amplification.
Meaning her current strength should be beyond his expectations.
So why did his expression look like… pity?
"Um… Remilia, do you feel any changes in your body?"
Ren couldn't hold back and asked.
Remilia stretched her body, clenching her fists with satisfaction.
"My physical strength has increased several times. My weaknesses are completely gone. I won't need a parasol in the morning anymore, how convenient! As for combat ability, I feel like I can defeat a hundred past versions of myself easily. Very good! When I return to Gensokyo, I'll kick Yukari like this, kick like that, and shout 'Old hag Yukari' in front of everyone. I'll let her taste social death!"
As she rambled on, her excitement grew uncontrollably.
Understandable—this wasn't a small upgrade; it was a complete leap in power.
Even she probably never imagined she could reach this level.
But Ren wasn't focused on that.
"Besides that, anything else?"
"Oh! My familiars! The ones I summon are far stronger than when the vassals used them. And controlling all eleven at once is effortless! Impressive, right?"
She shot a proud look at Giada, her gaze full of provocation.
It was as if she were saying, Want a duel?
Ren stayed silent, while Flandre walked forward with tiny steps.
Seeing Flandre approach, Remilia straightened proudly.
Yes. She was stronger now, more reliable. She had to show Flandre a dependable big sister.
But Flandre clearly didn't care about any of that.
Standing beside Remilia, Flandre compared their heights.
Then placed her head against Remilia's chest to check.
Then—
"What!? Big Sister is still the same height as before! Nothing really changed. This is so boring! I thought Big Sister would become this chesty, big-sister type. Before, lying on her chest was fine, but now lying on Patchy's chest is more comfortable. Still like lying on a steel plate… impossible!"
Pupu… each arrow of disappointment pierced Remilia's chest, making her realize all her previous happiness was meaningless.
Especially the last sentence, she could even imagine the scene.
She and Patchy had come to Flandre, inviting her to sleep, but Flandre ignored her and chose Patchy. She laid her head on Patchy's chest, listened to her stories, and fell asleep peacefully.
Meanwhile, Remilia was alone in her room.
The mental image was vivid.
Come to think of it, whenever they all went to the hot springs, Patchy's chest seemed to be the biggest in the Scarlet Devil Mansion.
Usually hidden under a robe, but at the hot springs, it was clearly visible.
Thinking of this, Remilia felt a wave of sadness.
Patchy… I can't believe you betrayed me too!
Then Remilia noticed the key problem.
Why am I still like this after becoming a Primogenitor? Not even Primogenitor's blood can save my height and figure unchanged for hundreds of years? I should be more like a big-sister type!
Ren watched this scene with slight regret.
But on second thought—head-in-hands defense! Eternal loli! Isn't that exactly Remilia's charm?
Without these, something would be missing.
Indeed, this version of Remilia looked better.
Thinking so, Ren quietly set aside his previous thoughts.
"With this, the Fourth Primogenitor has been successfully born, and this island will become the Empire of the Fourth Primogenitor!"
Watching Remilia, Natsuki unconsciously relaxed.
Perhaps because Remilia hadn't changed her personality despite becoming a Primogenitor.
She didn't lose herself to power. Still the same as before.
A mix of dignity, childishness, and humanity.
Such Remilia made her feel at ease…
Even if the next period would be a headache, she could get used to it.
However—"The Empires of the three Primogenitors, human nations, and the demon territories—all will have their balance disrupted by the Fourth Primogenitor's rise…"
Natsuki began to consider whether she would have to face former colleagues.
"Don't worry. Remilia has ambition, but not to that extent. She knows her limits, so what you imagine won't happen."
If Remilia were the type of ambitious person without self-awareness, she would have died in the Scarlet Mist Incident.
It was precisely because she was self-aware that she knew how to choose sides.
Her ambition always served the Scarlet Devil Mansion. Meaningless domination would only bore her.
"Then I'll handle the aftermath of the birth of Fourth Primogenitor. After all, I have a post here on Itogami Island. I don't want mass slaughter here. Remilia's side will also need a representative."
"You really like worrying about everything…"
Ren chuckled, but didn't comment further. It was Natsuki's responsible attitude.
"Why worry about trivial things? The birth of the Fourth Primogenitor or the establishment of the Empire—these are for us to decide. Those powerless under this tide must obey. Throughout history, those who don't adapt have only one outcome."
Harsh words, but Giada spoke accurately.
Natsuki narrowed her eyes, observing Giada.
This was probably how higher-ups think. Those without power could only operate within their own limits.
"I reserve my opinion. Giada has her considerations; I have my principles. Since I'm now an attack mage, I must consider matters from this post. I don't want large-scale destruction or killings in my area."
She said calmly and prepared to leave.
But Ren pulled her back, making Natsuki glance up.
This man… does he have some bad idea?
"While dealing with the Fourth Primogenitor, you may also need to handle other matters, Natsuki!"
"Other matters?"
What could that mean?
Before she could think further…
Boom! A shocking explosion appeared before her eyes.
Immediately after, Veldiana's disheveled figure appeared before everyone.
