HZk20-001	"We have arrived. This is the Mother Room."
HZk20-001	"In the centre is the main core. It is the Phantom Mist core that supplies all the energy of this city."
Versailles	"It's huge..."
Queensway	"But it's a lot smaller than the one in the Steel Tree. Of course, this main core is already big enough..."
Yoshino	"The construction of this room is also very interesting. I don't think Yoshino and friends could build or fix it with our technology."
Vivienne	"The main core is right next to the gate in question. It's definitely creepy, even creepier than the one in the M. Eisengrad Giant Tree."
Miyako	"It's not that big a Gate, but the amount of magic that flows through it is very immense..."
Conductor	We have confirmed both the main core and the Gate. There is also Phantom Mist, and what could be described as distorted magical power is filling this Mother Room.
Conductor	But there are no monsters in sight. Hertz, what's going on here? Are there ferocious monsters hiding somewhere?
HZk20-001	"Information is being updated. Please wait a moment."
HZk20-001	"......"
HZk20-001	"Confirmed."
HZk20-001	"The demons that were walking around in the Mother Room have completely disappeared. There is no record of them being transported to another location."
Conductor	It is difficult to believe that they disappeared spontaneously, given the circumstances. Could they have been elimited by someone?
HZk20-001	"It appears so. Divine Child of Iridescent Clouds. It is also recorded in the Mother that the cause was not of human hands, but of internal conflict between monsters."
HZk20-001	"A large number of monsters appeared from the dimensional rift, gained the power of the main core, went berserk and attacked each other at once, targeting all other monsters that were waling around the Mother Room."
HZk20-001	"It seems that they were quite special monsters. After the battle, records show that parts of its body did not disappear but remained."
Queensway	"Everybody, could you all take a look at this...?"
Queensway, who had been watching the perimeter, spotted something.
Queensway pointed to a spot. There is a large number of what looks like broken machine parts lying there.
Yakutsk	"Are those machine parts? It's been a long time since I've seen anything analog."
Putra	"That doesn't match the technology here. At least it doesn't feel like a part of this Mother Room."
Yoshino	"......"
Yoshino	"They are not machine parts."
Yoshino	"Isn't that right? Queensway?"
Queensway	"Miss Yoshino..."
Queensway	"...Yes. I don't think they're mere components."
Queensway	"That is the wreckage from a Machine Soldier. It looks very similar to the one we saw in the factory of northern St. Iris."
Versailles	"You're right... If I look closely, I can see parts like arms and heads."
Miyako	"These are people who have been turned into machines by the light of the Steel Tree. Why are they here?"
Versailles	"Maybe they were sucked into the Gate together with the Poison because they turned into machines and then into demons."
Yoshino	"It could also be the other way round."
Miyako	"Other way round?"
Yoshino	"It could be that they became machines after becoming demons. The Machine Soldiers of St. Iris were human at heart, weren't they?"
Yoshino	"If their hearts were still human, I don't think they would be sucked in with the Poison. Maybe they were sucked into the Gate after becoming like the Wandering Lives."
Queensway	"That seems more likely. Maybe they were affected by the Poison between dimensions and became machines."
Conductor	Whatever the order, whoever created this Gate would be a threat to the world. It means that people can be turned into demons or machines without being exposed to the light of the Steel Tree.
Conductor	This gate is not a gate powered by the Iridescent God. It is completely different in nature from those used by Mary and Yuuzen.
Miyako	"It is also different from the one made by the owner of Hinayashiki. It may even be a Gate that cannot exist in Iris Cloud or Iris Metro."
Yoshino	"That's why Hertz didn't call it a Gate, it's a lot smarter than Yoshino and friends. Super robot."
HZk20-001	"I'm sorry. I didn't say enough information either. I wish I could have explained the difference from what you imagine a Gate to be."
Conductor	Humans who have become demons and machines. Did they had a human heart when they faced the vicious demons in this unknown place...?
Putra	"I'm sure they were..."
Vivienne	"Putra?"
Putra	"They might have become demons. Their bodies might have been turned into machines too. But these people fought the demons while they were human here..."
Putra	"Before they came here, they might have been demons. But as they went through the Gate, came to the underwater city and heard the voice of the sea. The souls are revived when they hear the voices of those who live in the sea."
Vivienne	"...Yes. I'm sure it is."
Vivienne	"Putra is right. But... what makes you think that?"
Putra	"Because these people are... sailors."
Vivienne	"Sailors?"
Putra was alone, kneeling by a Machine Soldier lying on the floor. She reached into what she thought was the Machine Soldier's torso and retrieved 'something' that was there... and showed it to all of us.
Putra	"This is a navy insignia. These men were on board the M. Flamarine destroyers."
Vivienne	"M. Flamarine?"
Putra	"These are the people who helped us when we were conquering the Dark Celestial Sphere. The three ships at the front..."
Vivienne	"No way..."
Vivienne	"Are you sure you're not mistaken...?"
Putra	"I am not mistaken for sure. I spoke to these people at the operation meeting. We had dinner and drinks together."
Putra	"We talked... a lot about the sea."
Miyako	"All these insignia are authentic. The unit number also matches the naval unit that was sailing at the time, the most powerful warship unit M. Flamarine had ever boasted."
Versailles	"The ships that sank at that time have still not been found. None of the sailors have been found either..."
Miyako	"The Dark Celestial Sphere may have caused a dimensional rift in the sea. There's a Metro Hole there, so it wouldn't be surprising if it's connected to the Iris Cloud Sea."
Putra	"I didn't think they were in the Iris Cloud Sea. That's as good as I could have thought of. It was the best ship and the best crew."
Putra	"...I'll find everyone's ship. So don't worry."
Putra	"Thank you for defeating the monsters. Now leave the rest to us and get some rest."
Conductor	As for why the M. Flamarine sailors are in the waters of the Iris Cloud, it is not possible to determine at this time.
Conductor	It may be, as Miyako says, that the Dark Celestial Sphere caused a dimensional rift in the waters of the M. Flamarine.
Conductor	And one more thing. It is quite possible that the person who created the Gate here brought them here.
Conductor	If the creator of this Gate can manipulate it at will, it is by no means impossible to summon those submerged in the Metro Sea to this place.
???	"Good eye. As expected of the Divine Child of Iridescent Clouds. It doesn't seem like you're just a mere fuel source to supply the Train Knights with magical power."
Youko	"Good day even at the bottom of the sea. Always happy to see Youko."
Vivienne	"Youko... Why are you here...?"
Youko	"Ara, scary. Pretty little elf lady-san. You're not hiding your anger, are you?"
Youko	"The reason why I am here. Don't you already have some idea about that?"
Yakutsk	"I have absolutely no idea. Explain it to me with your own mouth."
Youko	"Then I will explain it to you briefly."
Youko	"I'm here to see what's going on at the dump."
Vivienne	"The dump...?"
Vivienne	"The dump? Why on earth would you call here that?"
Youko	"You know what I'm talking about, but it's not fair to keep asking questions. The dump is, of course, this underwater city. I am sending unwanted things here, such as 'Poisoned' demons."
Putra	"What is the purpose...?"
Youko	"Purpose?"
Putra	"Why on earth are you doing this for? What do you want by connecting the Gate here and sending the demons here?"
Youko	"Aah, this is troubling. It's not convenient to talk about that at this stage... No comment - Is what I will say here."
Putra	"Why did you show up in front of us? If your goal is to create Phantom Mist here, why did you, Youko bother coming at all?"
Youko	"I came to check on you because something unexpected happened. It seems that the demons I summoned from Iris Metro have killed my pets..."
Putra	"Demons summoned from Iris Metro?"
Youko	"Yes. It's that junk that's lying around here. I sent them in with the intention of feeding them to my pets, but the junk seemed to struggle unexpectedly under the influence of the Mist Core..."
Youko	"...The result was in-fighting to the death. I'm surprised that such incompetent machines could defeat my pets."
Putra	"They're not machines..."
Putra	"Nor are they demons. These people are humans..."
Youko	"They are not humans. Is your body made of metal?"
Putra	"THESE PEOPLE ARE HUMAN BEINGS!"
Vivienne	"Putra..."
Putra	"They're warriors of the sea who fought to defeat the King of Everlasting Darkness. The souls of the warriors will live forever with the sea."
Putra	"...Your pets were defeated by these warriors."
Conductor	...Putra, that's enough. Back off. There's no point in talking to Youko any more.
Conductor	Listen to me, all of you. That woman... Youko, is considered to be our enemy.
Miyako	"Affirmative, sir."
Versailles	"We'll maintain fighting positions. All personnel, form up."
Conductor	Youko... Gate user. The person who generated Mist by inducing an influx of otherworldly Poisons.
Conductor	Formerly 'a dangerous person whose identity is unknown', but as of now... she is completely our enemy.
Youko	"Please don't say that. I am not your enemy. Of course I am not your friend either."
Youko	"However, our goals are not exactly the same. If something happens that is detrimental to our mutual existence, it is inevitable that I will take action to prevent it."
Youko	"...My purpose is to let this Mist Core run amok. If you want to stop it, stop it. If you want to your life spared, return to the Mist Train now."
???	"----!"
Queensway	"The Gate just popped out a monster!"
Versailles	"Such intense magic. This is no mere Mist Monster."
Miyako	"It's emitting Phantom Mist along with its magical power. I have no doubt that this monster is the source of the Phantom Mist."
Yoshino	"The Gate's magical power is flowing into this monster. If we defeat it, we may be able to block the Gate."
Youko	"This is a good opportunity. Let's see how serious the SSS is."
Putra	"... Vivienne, cover me."
Vivienne	"Oui. Don't worry about anything. Just give it everything you've got."
Putra	"I'll do my best for everyone. We will win. I won't let the sea become a source of Phantom Mist."
