Paddington reported back to us and we rushed to the point where the mystery tunnel was located.
The tunnel turned out to be the Metro Hole that Versailles and Miyako had come through, as expected. The tunnel is large enough for the Train to come and go, and its construction indicates that it was built for the railway.
Queensway	"This is the Metro Hole..."
Yakutsk	"Surely the Mist Train could pass through a hole of this size."
Yoshino	"It's so dark that we can't see anything ahead at all. Versailles and Miyako are pretty fierce people who jumped in here. I guess a scaredy-cat like Yakky-tan would have to hold onto Yoshino's tail."
Yakutsk	"Of course not. I'm a soldier, you know? I'll jump into anything if I'm ordered to."
Yoshino	"Yosh, go right ahead, Yakutsk."
Yakutsk	"I won't go even if you order me to."
Queensway	"Miss Versailles, what's in the tunnel? I think it would be quite a distance to walk to Iris Metro."
Versailles	"If you go further in, there's a kind of door that reacts to magic. When we pass through it, we feel as if we are being suctioned by a strong force."
Versailles	"Perhaps it's a warp from the tunnel on the Metro side to the tunnel on the Iris Cloud side."
Versailles	"...But this is just our conjecture."
Miyako	"We only walked through the Metro Hole for a few hours, So we thought there might be some kind of trick to it..."
Mary	"You're making good headway for a conjecture. If there are doors that move through space, it makes sense for the Metro world. Perhaps it is a Gate that connects the Metro Hole."
Mary	"When you pass through a Metro Hole Gate, you enter the interstellar dimensional fault line. The two Gates are fixed in precise positions, and they're the liaison channel between Iris Cloud and Iris Metro."
Yoshino	"Gates are used to reduce the time needed to travel between Iris Cloud and Iris Metro. Objects that have a clear purpose of use are usually made by people..."
Yoshino	"If the Metro Holes are man-made, does that mean that the two worlds used to interact with each other?"
Versailles	"You mean a transporter that allows instantaneous long-distance travel? If so, it would explain why Miyako and I were able to reach this world. But is such a thing really possible?"
Mary	"Yes. In fact, there are portals in this world that distort dimensions and send people and objects to other places. If certain conditions are met, they can be teleported to where they want to go."
Versailles	"Are you familiar with Metro Holes, Mary? Are you a researcher in this field or something?"
Mary	"No, I don't. It's just that I can manipulate such forces."
Versailles	"You can use teleportation magic!?"
Mary	"It's not that big of a deal. I can open small Gates. Just enough for a person to get through."
Versailles	"That exactly what teleportation magic is! It's quite big, just big enough for a person to pass through."
Miyako	"Wow... The Knights of Iris Cloud can use such amazing sorcery..."
Versailles	"I can rely on you. If you're on our side, that is."
Mary	"Releasing a Gate is a special ability that is neither true magic nor sorcery. It is a kind of forbidden art that can be used with the help of the Guardians of the Giant Tree. But since Ricardo's death, I can't handle it as freely as I used to."
Versailles	"Wait a minute. Did Mary just say Guardian of the Giant Tree? Did you say you borrowed power from the Guardian of the Giant Tree?"
Mary	"Yes, she was a friend of mine who guarded the Giant Tree of St. Iris. She was the Divine Child of St. Iris, and Conductor's mother."
Queensway	"The Giant Tree of St. Iris was weakened by Poison from the otherworlds. It was protected by Lady Ricardo, the Guardian of the Giant Tree."
Mary	"Could it be that there are Guardians of the Giant Trees in your world too?"
Versailles	"We don't know if they exist or not, but there are legends about them. The Guardians of the Giant Trees are the pillars that hold up the world. They exist to maintain harmony in a world shrouded in Mist, supposedly."
Mary	"So there are five Guardians of the Giant Trees after all. Maybe there are four more guardians in the Metro world."
Queensway	"If that's the case, we need to protect the Guardians of the Giant Trees in Iris Metro from the Poison."
Mary	"Good eye. Now tell me why I think that."
Queensway	"Well umm... because Giant Trees other than St. Iris might also be contaminated with Poison?"
Mary	"Sixty five marks."
Queensway	"Ehh, that's harsh."
Yoshino	"No, it's not harsh. If anything, Mary gave you extra."
Queensway	"Do you understand that, Miss Yoshino?"
Yoshino	"Understand. Just as well. 'If there is a Gate connecting Iris Cloud and Iris Metro, then the five Giant Trees could also be connected both at the surface and subterranean.'"
Mary	"One hundred marks."
Queensway	"Eeh-!"
Yoshino	"Mufufu. You're not quite there yet, are you, Queensway-kun?"
Islington	"This is a Metro Hole, isn't it? It doesn't look dangerous at the moment."
Paddington	"It looks a bit like the tunnel we used when we went inside the Giant Tree. It looks like it's been railed, and there doesn't seem to be a problem with the Mist Train going through it."
Islington	"It's annoying. If this tunnel was just an underground tunnel, I'd jump right in, but the thought that it might have Gates is a bit..."
Islington	"What do you think, Mr. Conductor?"
Conductor	When I think about jumping into the Sea of Mist or the Giant Trees, I don't think it's as big a deal as going through an underground tunnel. If the world of Iris Metro is real, it is quite possible that it is connected to the place where Versailles and her friends were.
Conductor	Besides, it is no longer just an Iris Metro problem when a Metro Hole is appearing in this location. It's also an investigation within Iris Cloud, we should try to go deeper into the Metro Hole.
Islington	"What about you, Paddington?"
Paddington	"M, me?'
Islington	"You're the Divine Children of the House of Elrond and second-in-command to Conductor. What would I do without your opinion?"
Paddington	"Sister..."
Islington	"So? What do you think?"
Paddington	"Well..."
Paddington	"I think we should go. I feel this Metro Hole is telling us to 'go'."
Islington	"Heh..."
Paddington	"Both Iris Metro and Iris Cloud requires Conductor's power. I'm sure that this is a sign of Lady Ricardo's guidance."
Conductor	-Indeed, we have actively investigated and solved problems with objects that appeared in the Phantom Mist in the past. There have been many times when our lives have been in danger.
Conductor	But it was only by confronting it in this way and not running away that they were able to clear the Sea of Mist in St. Iris.
Paddington	"There are risks involved in both jumping into the Mist and continuing on the railway. We are prepared for it and we are on the Mist Train. We won't hesitate to go down the steel railway."
Islington	"Paddington, you've really grown up."
Paddington	"Huh!? Have I?"
Paddington	"If that's the case, it's thanks to Conductor♪"
Islington	"Well then, let's go and explore the tunnels a bit. We should investigate the Metro Hole before we take the train into it..."
Islington	"...Oof, this is not good."
Paddington	"?"
Mary	"...Queensway. Gather round everyone else. We're calling off the Metro Hole investigation for now."
Queensway	"What's wrong, Mary?"
Mary	"Prepare for battle. I can feel that we have nowhere to run."
Queensway	"Battle..."
Mary	"Get on with it now. Combat deployment. Phantom Mist. The power's extraordinary. Monsters equivalent to the Sea of Mist are swarming towards us."
Queensway	"Why is there so much Phantom Mist here like it's the Sea of Mist!?"
Mary	"Focus on protecting Conductor and Paddington more than Islington. Don't wait for Vivienne and Putra, they're on guard duty. Consider retreating."
Queensway	"Affirmative!"
Queensway	"Everybody, prepare for battle! We've detected a Phantom Mist outbreak! It's quite a formidable foe. Stay alert!"
Versailles	"The Metro Hole has called up a Phantom Mist. Day and night don't seem to matter in this world."
Versailles	"Miss Queensway! Miyako and I will join you!"
Queensway	"You two are not in perfect condition. Leave this to us."
Versailles	"No, that's not possible. Miyako and I are the assault squad of the M. Allied Forces. Our mission is to fight the Phantom Mist. We are just like you, Queensway."
Queensway	"But..."
Miyako	"Don't worry. I can fight, and so can Versailles. We will never get in your way."
Miyako	"Besides, we have never once fought on the Metro Hole fronts in 'perfect condition'. We are used to tough battles."
Queensway	"I understand. Thank you for your assistance."
Versailles	"Miyako, do you know how many enemies we have?"
Miyako	"I can't detect them yet. Only Mary-san, Islington-sama and Conductor-san seem to be aware of the Phantom Mist."
Versailles	"While it has similar characteristics to our underground enemies, We won't know until we get into engagement range..."
Conductor	...But they are definitely coming. Mary is right, I feel a very strong force.
Conductor	A very thick Mist is pushing in over the Metro Hole. I'm more worried about the magical nature of the Phantom Mist than the number and nature of the monsters.
Queensway	"Everybody, look over there!"
Putra	"Woooi! You all!"
Vivienne	"Hurry up and get on the train! It's Phantom Mist! It's chasing me and you, Putra!"
Queensway	"Miss Putra and Miss Vivienne!"
Yakutsk	"Hey, what's that Mist behind them? It's like a mudslide coming at them!"
Mary	"It's not good. If that thing swallows them up, they might not make it back."
Queensway	"Miss Putra! Miss Vivienne! Hurry! Don't get caught in that Mist! Get on the train, quickly!"
Putra	"As much as I want to... it's already getting close to us."
Vivienne	"What do we do, Putra? It's now or never if you want to change course?"
Putra	"......"
Putra	"...Let's go away from the Metro Hole. We can't drag the Mist towards Conductor and everyone else."
Vivienne	"Alright. Let's run to the high ground over there."
Queensway	"You changed course!? Where on earth are you two going!"
Versailles	"They can't pull away, so they're trying to bait them. Putra and Vivienne are thinking that they are the target of the Phantom Mist."
Queensway	"No!?"
Miyako	"The Phantom Mist is not aiming Putra-san and Vivienne-san, but at the Metro Hole. It should be heading straight towards us. At this rate, Putra-san and the others will surely be engulfed by the Phantom Mist."
Versailles	"Putra! Vivienne! Do not change course! Miyako and I will go to your aid!"
Versailles	"Let's go, Miyako!"
Miyako	"Hai!"
Queensway	"No, stop, you two!"
Queensway	"That's crazy..."
Mary	"No, it's the best way to save everybody. They've been chosen as emissaries, I suspect that they've been through the ringer many times."
Mary	"Queensway, we're going after those two. All of you cover Putra and Vivienne's evasive manoeuvres. The fallback point is this Metro Hole. We're not moving towards the city centre until we see where that Phantom Mist is headed."
Queensway	"Affirmative!"
