Brittany	"I don't see any suspicious devices. Nor do I sense any powers that act against non-shana."
Brittany	"The problem is how to break the seal... It seems to me that we have to pour magic power directly into it."
Vivienne	"So does that mean it's Conductor's turn?"
Brittany	"Pas assez, Sir Conductor's power will not be able to break it. It is the Chosen Child of Thunderclouds who will break the seal and open the way."
Versailles	"The Chosen Child of the Thunderclouds refers to the Shana tribe. So you are saying that Brittany and I are the key to unlocking the seal?"
Brittany	"I think so. I was right to go with you, after all, and as Mademoiselle Euston said, there must have been a good reason why lightning struck that spot today."
Brittany	"Mademoiselle Versailles, give me your hand here. Do you see a slight indentation?"
Versailles	"Oui, I can see it."
Brittany	"When I give you the signal, put some magic into it. That might get us to the other side."
Versailles	"Can I even do that..."
Brittany	"Certainly. You are a shana. You meet the requirements."
Versailles	"But I'm not good at using this kind of magic. I am not blessed with magical powers as a child, which is rare among the shana people..."
Brittany	"It doesn't matter. What matters is whether you are the Chosen Child of Thunderclouds."
Brittany	"You and I are one family. My fellow swordswoman of the shana tribe."
Versailles	"Miss Brittany..."
Putra	"Hey Vivienne, don't you feel that Brittany is a bit different today?"
Vivienne	"Oui bien sûr. After all, they two are shana."
Vivienne	"The shana are very close and protective of their people. Regardless of birth or upbringing, the shana are all family together."
Putra	"Rennes is an elf. She's not really Renne's older sister."
Vivienne	"Don't say that. That's rude. Especially when she is with the shana tribe."
Putra	"Ah, right. So sorry."
Brittany	"On the count of three. Three, two, one..."
Brittany	"NOW!"
Brittany and Versailles worked together and cast their magic power into the wall. Unleashed at the perfect moment, the duo's magic became a single spell and emitted enough light to illuminate the inside of the tunnel in white light.
However, the 'seal' did not react to the two shana.
Brittany	"Nothing seems to be happening, huh."
Versailles	"Oui, nothing happened, other than generating a powerful magic."
Brittany	"Something must have been missing. I don't think there's any mistake in decoding the message..."
Vivienne	"......"
Vivienne	"The Power of the Clear Sky is too strong for the Chosen Child of Thunderclouds alone. Enlist the help of those who mastered over End of Light, those who make the Night their ally."
Putra	"Vivienne, what are you talking about?"
Vivienne	"The Clouds and Mist that cover the celestial sphere have unleashed the Princess of Thunder. That which must not be unravelled revives the incomplete steel railway."
Vivienne	"Open the true path. The End of Light splits the Night."
Versailles	"Has Miss Vivienne gone mad?“
Euston	"Obviously something is wrong. Has someone possessed her?"
Putra	"No, probably not."
Putra	"Vivienne is the same Vivienne she's always been. She's just using a power she doesn't normally show much of."
Putra	"Isn't that right, Vivienne?"
Vivienne	"......"
Vivienne	"We will open the door to the ruins. Those without power, get out of our sight."
Putra	"Yes, okay."
Putra	"Everyone, Vivienne will use her magic. Stay away from the wall so you don't get caught in it."
Vivienne was clearly acting differently than usual, but Putra treated her normally and approached her.
Vivienne warned her that she would 'break the seal', but she did not seem to respond to Putra's call.
However, what Putra said about 'using strong magic' was probably true. Vivienne pointed her hands at the wall, and she chanted what sounded like an unfamiliar incantation very rapidly.
-It's the same as that time. It's all right.
Muttered Putra, who was watching her best friend just behind Vivienne.
Vivienne	"We have identified two sigils. We will now open the entrance to the Ruins of Thunder."
Queensway	"There are ruins beyond the wall!"
Queensway	"Miss Vivienne, you said 'Ruins of Thunder', didn't you? So that means..."
Yakutsk	"The Metro Hole was the Ruins of Thunder!"
Yoshino	"No, it wasn't."
Yakutsk	"......"
Yakutsk	"Really?"
Yoshino	"Really, no."
Yakutsk	"......"
Yakutsk	"F-Fine, let's see what Yoshino has to say then."
Yoshino	"The only correct thing is that this stop was directly connected to the 'Ruins of Thunder'."
Yakutsk	"Oh, right! That's right! I just got confused with my wording that's all!"
Yoshino	"And by the way, the train slowed down, most likely in response to the entrance to these ruins."
Yoshino	"Maa, just my personal opinion'."
Vivienne	"......"
Putra	"Vivienne, are you okay?"
Vivienne	"Oui, I'm okay. I'm fine. I'm not crazy."
Putra	"I know that, Vivienne is not crazy."
Putra	"That's what you just said. It's just that the message from the seal on the ruins popped into your head."
Vivienne	"Yes, that's exactly how it was. I heard Putra's voice and it was my intention to use magic."
Putra	"Then there's nothing wrong with it. The two shana did the same thing, it's okay."
Putra	"So let's move on, shall we? I'll stop you if anything goes wrong.
Vivienne	"Oui, you're right..."
Vivienne	"......"
Vivienne	"Hey, Putra."
Putra	"What?"
Vivienne	"Will you really stop me, when the time comes?"
Putra	"Leave it to me. Conductor and I will definitely do so."
Vivienne	"Thank you, Putra."
Versailles	"......?"
Brittany	"Something wrong, Mademoiselle Versailles?"
Versailles	"Did you see any movement over there just now?"
Versailles	"A monster!"
Brittany	"And that monster is from Iris Cloud. I fought those once before when Brocéliande was shrouded in Mist."
Versailles	"So Mist Monsters are flowing into Metro after all. If they are inside the ruins, then the source could be there too!"
Monster	"......"
Monster	"!"
Versailles	"It's gone to the back! Let's go after it!"
Brittany	"Mademoiselle Versailles! Slow down!"
Brittany	"......"
Euston	"I apologise for any inconvenience my subordinate has caused you. I'll give her a stern talking-to later."
Brittany	"Non, Mademoiselle Euston, it's not something you should apologise for..."
Euston	"Not true. Her own actions are my responsibility. I could have stopped her before that. But I didn't do it."
Brittany	"?"
Euston	"I thought it was better to let her go, Versailles has such a keen sense of smell. There's always something going on where she's going. It's always been that way."
Euston	"Let's go. If anything goes wrong, I'll take responsibility."
Brittany	"Mademoiselle Euston..."
Vivienne	"Brittany, what are you waiting for? We're going after Versailles as quickly as we can."
Brittany	"Ou-Oui!"
