The Special Steel Squad cleared the Mist that had manifested in M. Verforet's Ruins of Thunder. The peace of the ruins had been shattered by the Fairy Princess of Thunder turned monster, the former guardian of the altar, but that was not the only problem.
Canaria of the radical Resistance faction is still alive.
Canaria had been swallowed up by the Voltarja Celestial Sphere, but somehow she's back in our sights again.
...She came back with deadly strength too.
The lightning that Vivienne struck down on the altar became teleportation magic and Canaria fled into the light of the teleportation magic to escape from us.
Canaria	"WHO'S FIGHTING? DUMBASSES!"
Versailles	"Oh no! It's Brocéliande beyond that point!"
Vivienne	"...I won't let her go to Brocéliande."
Brittany	"Mademoiselle Vivienne?"
Vivienne	"She will go somewhere else. Everyone get away from there. I'll fire one more shot, a big one."
Vivienne changed Canaria's destination with her lightning bow so that Canaria would not head towards Brocéliande. When she did so, we saw the M. Flamarine altar for a brief moment.
Canaria fled to M. Flamarine. Having read that teleportation magic has the ability to send people and objects from one altar to another, we started to investigate whether M. Flamarine had an altar similar to the one in the Ruins of Thunder.
As for the location of the altar. It didn't take us long to find out where it was.
Putra	"So this is Flamarine in Iris Metro? The mining zone looks just like 'up there'."
Putra	"But I didn't think they even had the same name... I didn't realise the Banská Mines are in Metro."
Conductor	Banská Mines. This is the name of a huge mine in Flamarine, Iris Cloud. It is also the birthplace of Train Knight Stia.
Conductor	It was discovered that the Banská Mines are also in Iris Metro. This is a world that is connected 'up' and 'down', so it's not impossible.
Queensway	"Since the two worlds share the same country name, it's possible that we might find other common names for places and facilities besides the Banská Mines."
Vivienne	"Hey Putra, your mother used to work at the Banská Mines, didn't she? Didn't she bring you there when you were little or something?"
Putra	"It's true that my mum used to work in Banská, but that was a long time ago. I don't think she's descended deep in Banská since I was born."
Putra	"But I don't think mothers should take their children to work anyway. Especially as, unlike Stia, I am not a woman of the mountains. A woman of the sea shouldn't carelessly go into the mountains."
Vivienne	"Because it's dangerous?"
Putra	"Yes. Banská is not a place to venture deep just for sightseeing. It's a labyrinth inside, and if you descend too deep, you get a lot of Phantom Mist."
Putra	"My mum is in charge of the lower levels, which are the most dangerous in any part of the mountain. I remember she said she's been to the 'deeper layers' a few times."
Putra	"My mum's only souvenirs were the scary stories she told me..."
Islington	"I guess we have to go there even if it's scary~ After all, we found an altar in the Banská Mines."
Queensway	"Lady Islington."
Islington	"Good morning, ladies. Sorry to make you move around so much. Did you sleep well on the train?"
Putra	"I didn't sleep a wink."
Vivienne	"Me neither. I was a bit preoccupied."
Islington	"Welp, it can't be helped in these circumstances. The only one who slept like a baby was Yoshino."
Putra	"I'm surprised the Banská Mine is in Metro, but I can't get to sleep when Canaria fled in there."
Putra	"After all, if we don't solve Metro's problems, Iris Cloud's Flamarine is going to get more and more polluted I guess?"
Islington	"Unfortunately, that's the way I see it at the moment. The appearance of a Metro Hole in Flamarine after the Mist lifted at the Ruins of Thunder was decisive."
Islington	"It's not a good sign when the top and bottom are connected, as was the case at St. Iris and at Verforet."
Mary	"It was almost as Islington predicted it - Iris Cloud and Iris Metro are linked. There were incidents at both Flamarines at the same time."
Mary	"Well, I didn't expect to altar to be discovered so easily. Did you know there was an altar here all along?"
Islington	"Of course not. I just took a lucky bite in the most dangerous parts of the mining area."
Mary	"That's how good the advance detachment was, you were right to send Khabarovsk."
Putra	"Hold up, Mary. You're forgetting something important. Khabarovsk has a strong partner this time."
Mary	"Oh right, she also has Skanda's battle-thirsty maniac with her."
Conductor	This time it was Khabarovsk and Batu who descended into the M.Flamarine mining areas a step ahead of us as an advance party. They found the altar together with the M. Flamarine Railway Army.
Conductor	That was all well and good, but after finding the altar, there was a thick Mist all over the mine. M. Flamarine Railway Army was quick to respond in that direction, but they seemed to be struggling and we the SSS had been deployed to support them as reinforcements.
Conductor	Our objective is to explore the mine as the "altar team", to search for the fugitive Canaria and the final key.
Conductor	Islington, Mary, Finchley and Euston will be the surface team. They will join up with Khabarovsk to eliminate the Phantom Mist outside the mines.
Yoshino	"Batu joins Yoshino and friends' altar team. Khabarovsk joins Islington's team. It looks like we're split into the big sisters team and the little girls team."
Islington	"Are you coming to this team too, my little Yoshino~?"
Yoshino	"Yoshino will keep that in mind. Yoshino is not full of adult miryoku yet."
Finchley	"On the big sisters team..."
Finchley	"I am? On the big sisters team?"
Mary	"Well, better big sister than being an aunt, you know?"
Finchley	"......"
Mary	"Good luck with that. 'Teach'. I don't know when I'm going to separate from the ground troops."
Finchley	"What do you mean?"
Mary	"Depending on the situation, I may detach myself from Islington's unit and go on the lam. I can't say who, but I have 'volunteers' who might be able to lend a hand."
Finchley	"I see. 'those cards up your sleeve'?"
Mary	"Yes. Back-up. Eh, this is an operation that could have been done without me in the first place, Finchley and Euston would have been enough to escort our Divine Child."
Finchley	"Of course. I will do my best as a knight."
Mary	"Too polite. I am not your superior officer you know."
Islington	"So, my fellow elite troops... Are you ready? Now that you're all here, let's begin operations post haste. If we're too slow, daylight's gonna end."
Islington	"Mr. Conductor, I ask you to take care of this. I'm sorry I can't always be there when you need me, but I've got my own things to do."
Conductor	Don't worry about it. It's only at crucial moments that it's better to split up. A soldier is a soldier. A Divine Child does his or her divine duties. Everyone has different things to do for each other.
Islington	"There's a big battle coming. Don't die, ever."
Conductor	Let me repeat what you've said back to you. It would be a great loss for the whole world to lose a dependable Divine Child. Personally, I'd hate to no longer be able to work together with Islington.
Islington	"Good gosh, aren't you a guy good with words? When the world is at peace, I'll take you as my son-in-law."
Islington	"Now, big sisters team, gather round. We've kept Khabarovsk waiting a bit too long. It would be a shame if she died waiting for us."
Euston	Versailles, Miyako. You've got to up your ante. This is Iris Metro. We can't rely on the 'surface' for everything."
Versailles	"Leave it to me. I will find the key."
Euston	"Excellent. Don't forget what we're here for."
Miyako	"Don't worry, Euston-san. This time I'll keep a good eye on Versailles."
Euston	"Counting on you two. You both can overcome any difficulty. I am proud of my men."
Versailles	"Sir Knight Commander Euston, please take care."
Finchley	"Queensway."
Queensway	"Yes."
Finchley	"I can't help you this time. You've got to get it right. Don't just rely on your swordsmanship, always use your head. Don't make incorrect judgements on what you should do. At the same time, don't be afraid to make decisions."
Finchley	"In extreme situations, there are no perfect answers. So in addition to good judgement, you have to be decisive. Sometimes you have to be quick. It's very common to be gone due to Mist before you can make a move."
Queensway	"Yes. I'll bear that in mind."
Queensway	"......"
Queensway	"Um, Instructor Finchley."
Finchley	"Yes?"
Queensway	"As Instructor Finchley said, Train Knights need to have good judgement and determination."
Queensway	"But I think the kind of judgements and decisions one makes depends on the situation at the time."
Finchley	"Yeah, you're right about that, so... what about it?"
Queensway	"Who is the commander, and who is the subordinate. The appropriate instructions and orders depend on that. For example, Miss Blackfriar and Miss Ohana would probably give us different orders."
Finchley	"That would be true. Those two have such different ways of fighting and thinking."
Queensway	"Yes, Miss Blackfriar is the commander of the Out-Siders and Miss Ohana is the matron of the student dorms."
Queensway	"But is Ohana weak?"
Queensway	"Wouldn't she make a good commander if she was given command of a unit?"
Finchley	"......"
Queensway	"No, sir. I am sure that Miss Ohana will command the unit with distinction."
Queensway	"Miss Blackfriar and Miss Euston are excellent commanders. But I think that Miss Ohana and Instructor Finchley are just as good commanders. It's just that their usual role and the way they think is a little bit different..."
Finchley	"Queensway..."
Queensway	"Please excuse me! I didn't mean to..."
Queensway	"But let me just say this. I was lucky to fight in the same unit as Instructor Finchley. I learned a lot under an excellent commander."
Finchley	"...Me too. It was an honour to fight alongside you."
Finchley	"Don't ever die, Queensway. You'll live to fight to the end."
Queensway	"Yes, and good luck to you too, Instructor Finchley."
Finchley	"Did she overheard what I blurted out to Euston in the Ruins of Thunder?"
Finchley	"I'm the one who's learning from you."
Iris Cloud and Iris Metro. The Banská Mines, a mining area common to the two Flamarine countries.
In order to clear the simultaneous outbreak of a massive Phantom Mist, a large-scale operation has been launched by the allied forces of the two worlds to find the final key to freeing the Guardians of the Giant Trees.
We have to search for the key while clearing the source of the Phantom Mist. The surface and the subterranean worlds are probably full of Mist. No doubt this would be a dangerous mission.
But we don't have much time left.
Not just Canaria, a fugitive on the run, the anomalies in Iris Metro's celestial spheres have also had a negative impact on Iris Cloud, which has significantly increased the number of Mist outbreaks on several areas.
Is this all due to the disappearance of the Guardians from the Giant Trees? To find out, we must obtain the last key and meet the Guardians of the Giant Trees.
