Is it the Mist or the clouds that keep the night going? ......
The subterranean people do not know clouds. They call the Mist that hangs over the celestial sphere a cloud. They do not know that it is Poison.
The people of the earth do not know the sea. They call the end of the hot sand, the purified magical world, the sea. They do not recognise the Poison hidden in the four magical worlds.
The monsters created by the steel railway and the celestial sphere consume the Poison. The Poison seeks tunnels and doors in search of a place to escape. Giant Trees unprotected by Mist are suitable places for the Poison to stay.
Ever-darkness envelops places where there is little Mist. The King of Ever-Darkness creates Mist. The Mist shall cover the skies of the world once more.
I am the King of Ever-Darkness.
I will extinguish every single light in the depths of the subterranean realm, and build a world of complete darkness.
Is it the Mist or the clouds that keep the night going...?
Queensway	"We seem to be slowing down."
Yakutsk	"We must be through the gate. I see a little light ahead."
Queensway	"Does that mean we've reached Iris Metro?"
Yakutsk	"Seems like it's going to be."
Yoshino	"Or another world that is neither Iris Metro nor Iris Cloud. It is possible that we have gone to a scary place from which we can never return."
Yakutsk	"What? Why are you looking at my face?"
Yoshino	"Just checking to see if you're scared, Yakky-tan."
Yakutsk	"You're brutally honest there."
Yoshino	"Yoshino's a maiden who knows no shame."
Paddington	"Ladies and gentlemen, we can see the tunnel exit ahead! We're stopping near the exit, just in case! Please hold onto the nearest handrail or strap in case of turbulence!"
Putra	"Vivienne, hold on!"
Vivienne	"I've got you! I've got a fluffy strap!"
Yoshino	"Chotto chotto chotto. That's not a strap, that's Yoshino."
Versailles	"It's probably Nacht around the Metro Hole. A battle is immediate when we arrive. Get out of the vehicle immediately and clear a path."
Versailles	"Once the path is clear, get the Mist Train as far away from the Metro Hole as possible. Combat personnel should accompany the Train and be ready to board it at any time."
Yakutsk	"That girl's a Metro girl alright. She's quite used to fighting on the railways..."
Versailles	"We're going through the tunnel. Miyako, ready?"
Miyako	"Yes. Survival is more important than destruction. I promised you we would come back."
Versailles	"I understand. We'll all come back alive."
Queensway	"So this is Iris Metro..."
Vivienne	"There really is no sky. It's night and I can't see the Moon or the stars."
Yakutsk	"So it's dark here because the celestial sphere has disappeared. It's so strange to live in a world without the Sun."
Versailles	"It's Nacht after all. But that's impossible, it's been the same since we left here..."
Miyako	"But it's Nacht and nobody's here? No Phantom Mist, no Mist Monster."
Versailles	"Perhaps they couldn't hold out anymore and retreated to the second holdout. I don't know why there is no sign of the demons, though."
Miyako	"No signs of a battle either."
Yoshino	"Both the Phantom Mist and the monsters followed those who retreated. That's why there is no one here at all."
Versailles	"Possibly a tactical retreat seeing that they couldn't cope with the Phantom Mist from Iris Cloud..."
Miyako	"Yes, that's true. If a Phantom Mist of that scale headed towards the city, it would be a catastrophe. The strike force moved out, likely drawing the Phantom Mist away before that could happen."
Islington	Versailles, Miyako. Are you sure this is where you were fighting? The dangerous Metro Hole that breathes Mist during the Nacht."
Versailles	"Oui, that's right. But we believe the strike force has moved on to another location. Perhaps they have decided that it is no longer possible to continue the battle here."
Islington	"I see not a single man, but that means they've all retreated. Can they abandon such an important place?"
Versailles	"Non. Abandoning the Metro Hole and retreating is only a last resort. A detachment will be dispatched as soon as the second holdout is ready."
Mary	"What should we do? I'd like to hear your views."
Islington	"Do we go to your people now? Or do we stay here and build a new defensive base?"
Versailles	"......"
Versailles	"...Neither. We should hit the source of this Phantom Mist as soon as possible."
Versailles	"This Nacht is brought about by the celestial sphere directly above the Metro Hole. Should the celestial sphere act unusually, it usually involves the Phantom Mist on the ground."
Miyako	"By striking the source, the source of the outbreak, the anomalies in the area should be eliminated. Our target is directly under the celestial sphere. That means there is something in this forest where the Metro Hole appeared."
Mary	"But the Metro strike force wasn't up to the task of investigating the forest. The area is crawling with such powerful enemies."
Versailles	"Oui. But it is possible to explore the forest now, this time with the Iris Cloud's Divine Child and the elite troops with us. I'm sure we can clear the Mist that has settled here."
Versailles	"When the Mist clears, the Nacht will also clear. If the Celestial Sphere is restored to its original state, the situation will be reversed at once."
Mary	"Well said. That's why you are a knight."
Mary	"I agree with her, Conductor. We should take this opportunity to hit the source of the outbreak rather than chasing after the retreating strike force."
Mary	"I'm not sure what you mean by Nacht, but I have the impression that the lights have gone out because of the Mist."
Versailles	"Oui! That's what I meant!"
Yakutsk	"What's this evil atmosphere I'm feeling...?"
Queensway	"Ugh, it's disgusting. What is this feeling? I've never experienced this before. I don't want to be here any longer..."
Versailles	"This signifies the presence of the things that inhabit this place at Nacht. It will take some time to get used to it, but one can endure it if they keep their wits about."
Miyako	"Be careful, everyone. Mist occurs at times like this. All lighting fixtures using Mist stones will become unusable. As soon as darkness envelops, use magic to illuminate the area."
Miyako	"Even if you can't see anything, please don't panic. This is called 'ever-darkness'. It is a phenomenon of Nacht that the more you fear it, the more you will be stuck in it."
Queensway	(Versailles and Miyako are incredibly calm. Even though this power is worse than the magical pressure felt in the Sea of Fog...)
--The Divine Children of the Iridescent Clouds have arrived.
--He who lives in clouds and sunshine cannot live in darkness.
--Mist over the steel railway and the celestial sphere creates darkness.
--Is it the Mist or the clouds that keep the night going?
Versailles	"I heard a voice out of the ever-darkness. I've never heard anything like this before."
Queensway	"Whoever that voice is, he could be the source of the Phantom Mist, perhaps a negative effect on the celestial sphere."
Versailles	"I'm sure he is. He is reacting to Conductor. He's trying to drag us into this ever-darkness this way."
Islington	"Is that so? That's lovely then."
Versailles	"...What?"
Mary	"Hear hear. We should accept the convenient invitation. Wouldn't you agree, Conductor?"
Conductor	Absolutely. This black Mist of ever-darkness, or whatever it's called, is a nuisance, but it's lucky that they contacted us from the other side. It will be easier for us to fight them because we don't have to worry about them escaping.
Versailles	"Conductor..."
Miyako	"Um, What is this black Mist?"
Conductor	It's the menacing magical power we are feeling right now. There is an even deeper blackness mixed in with the darkness of the night. Although we cannot see it, this eerie feeling is the Phantom Mist itself. There are probably many monsters lurking in this ever-darkness.
Miyako	"I see, so the ever-darkness has properties like Phantom Mist. Maybe that's why the mysterious phenomena were happening..."
Conductor	For us on the side of Iris Cloud, this kind of development is rather favourable. The Mist Train's Conductor is a natural target for the Phantom Mist. They will not now let an opportunity slip away on the chance that our lives are in danger.
Conductor	SSS. Begin operations. We will take on the suspicious things lurking in this ever-darkness. Whether the Mist of the Metro Hole will lift or not remains to be seen. We'll find out when it's daytime here.
Queensway & Yakutsk & Vivienne	"Roger."
Islington	"...Now that's what we're thinking."
Mary	"They're all still young and inexperienced, but they've all been through their fair share of carnage."
Versailles	"So this is the SSS, saviours of the Iris Cloud Railways..."
Miyako	"We can't be outdone either."
Versailles	"True, we cannot. We can't be outdone..."
Versailles	"We are the Iris Metro Railway Army. We are the subterranean army long accustomed to fighting in long Nachts."
Versailles	"Let's go, Miyako, we must lead the way to be the eyes of the Special Railway Corps."
Miyako	"Yes, I'll follow you. Just like I've always done."
