Editing BlazBlue:Phase 0 Chapter 5 (section)

===Part 1===

The out of place door which Trinity had discovered was pretty plain.

According to Celica, the door had an old lock that was quite simple. Ragna easily opened it with just a few kicks.

What awaited there was a thin, dark passage. Unlike other places, this passage didn't have any illumination. In the first place, there didn't seem to be any lighting installed.

Relying on the light Trinity had made with magic, they advanced inside with Ragna as the lead. Then, they reached somewhere. But there was only another door that stood still inside the dark passage.

"This one has an electronic lock."

Celica, who was walking behind Ragna, said that while looking at the small panel beside the door. They weren't sure whether if it was thanks to the electric source of the whole facility that was still active, or if it had an independent electric source, but the lock was functioning securely.

Ragna tried to knock it lightly. The security here was tighter unlike at the entrance. It didn't seem to budge no matter how many times it was kicked.

"So, what do we do? Frankly, it's too much effort to break it off by beating it."

"It's also too dangerous to just blast the door off. We might get caught in it."

Recalling the time when she was about to blow the elevator's door, Nine quickly said it while shaking her head. But there was a smile without any worry whatsoever on her expression.

"So, we'll do it like this."

While saying it, Nine's supple fingers sparkled. Thin electric currents from her fingers shocked the electronic panel. Sparks scattered around.

A moment later, the secure bulky door was separated in the middle. It sluggishly started to open its upper and lower ends.

"Seriously...?"

"Onee-chan's amazing..."

Having too quickly cleared their objective, Ragna and Celica couldn't help but mutter their admiration.

"Fufu", smiled Nine triumphantly.

"If you construct a system so advanced to a certain point, it actually becomes easier for the user to understand what the system's saying."

Different from the previous elevator that had stopped functioning smoothly, this one was still working. Perhaps instead of 'understand what the system's saying', maybe 'you could forcefully bash it as you like' was more appropriate.

Nine shook off the remaining electricity which was coiling around her fingers as if removing intertwined threads.

Although the passage from the entrance until then was narrow, what lie in wait inside was an unexpectedly spacious room.

Rather than a room, it might have been better to call it a square.

When they first entered, the color of the illumination took over their visions. It was like it was dominating the room. As if the dark passage until now was a lie, the sophisticated and refreshing green-colored lights shone on.

The room had an elliptical landscape.

Within the interior that was surrounded by metallic plates, there were several machineries installed that seemed like measuring devices. It appeared some kind of development was being conducted. The desk where there was a computer put on had a large quantity of papers scattered around its perimeter. Several of them were stuck on the wall using tape.

However, it could be said that an unknown discomfort was drifting within the room.

"What's with this room...? It's like time is almost not moving~"

The first one to notice the source of their discomfort was Trinity. With uneasiness clouding her face, she turned about and looked around the room

Just as she had said, this room was odd.

Not having any of the Black Beast's scratch, it was spotless. It was as if just a few days ago, or maybe a few hours ago, since the last time someone had used it. The air flowing there had little to do with destruction and deterioration.

It didn't have any smell of dust or rust. It added more of the eeriness.

"I feel like we've wandered to a strange location."

While speaking bitterly, Nine cautiously proceeded to the inner part of the room.

Suddenly, the atmosphere which had wrapped around Ragna's group up until now trembled and vanished.

Trinity had dispelled her protective magic.

"We don't seem to need it for a while now."

Certainly, the air that was contaminating the First District which could roast their internal organs if they had no means of protection didn't seem to be there anymore. There was only clean air drifting about. It was fine to take a deep breath.

It wasn't only this room. The air within the cave from before where the Cauldron existed was also clear. The substance called seithr that was overflowing from the Cauldron neutralized the radiation and other harmful chemical substances. It didn't seem harmful. Instead, it even produced hygienic air.

But the only one in this room who understood its structure just by feeling it on her skin was Nine.

"A hidden room, huh."

Inhaling the strangely refreshing air which had been released by the seithr, Ragna walked within the room. He picked up a piece of paper that fell at his feet.

The bluish-green lightings were dim, but unexpectedly the small letters were legible. But since the writing was in Japanese, it was nothing more than cryptic letters he had never seen before. 

Even though he didn't know the letters, Ragna understood the drawing. Ragna frowned at the numerous scribbles along with the hand drawing that was on the center of the paper.

There was something like... a large nail on it. It seemed to be a diagram for something. It was probably a blueprint or even something else entirely.

From the side, Celica peeked on what Ragna was holding.

"What's this? Something like a machine? It's like a nail... Ah!"

Inadvertently lifting her gaze just now, Celica made a loud voice. At the same time, she pointed toward the inner part of the room.

Silently blending within the green lightings, a gigantic object shaped like nail was hanging in the air alongside the wall.

If it was a nail, then it should have had crude silhouette. Yet it was so fascinating that it was like an ornament decorating the room. The green patterns stood out on the aesthetic silver surface. Metals and metals joined up together and drew straight lines. Those lines appeared to give off a calculated charm.

Ragna felt that its size, whether its height or width, could easily fit approximately three to four people. It might have been because of the lighting, but it could have possibly bene even larger.

It had a rather sacred feel drifting around as if it was a nail-shaped goddess statue. The beautiful main part was clad in several silver chains. The stakes pierced strongly to the ceiling and wall.

"Isn't this drawing actually about it?"

According to what Celica was pointing out, the drawing on the paper Ragna picked up was the blueprint for the captivating gigantic nail of an objet d'art.

If so, it seemed someone had created it as some kind of a device. That thought seemed unbelievable. Just how much of technology, knowledge, and insight was needed to create this kind of object?

The kind of dread like the Cauldron had crept up to Ragna's nape.

"It seems so. But how come this thing exists near the Cauldron?"

A hidden room even got built for it.

"This room's probably built to observe that Cauldron."

Trinity spoke while playing around with a computer a bit separated from them.

Ragna was surprised on how she handled it. Sometimes, he could see that there were small emblems shining on her fingertips. Perhaps she was borrowing the power of magic. At any rate, it was a handy magic.

Pushing up her big glasses, Trinity turned on the sub-display and showed it to Ragna and the others.

The view there was looking down from somewhere as it projected the front view of the Cauldron from before.

"Looking at this camera, it seems to be recording the changes in the atmosphere around the Cauldron, like temperature and humidity~. In addition, a lot of data is flowing in."

"Then... this device is also related to the Cauldron and Boundary, huh?"

Ragna took a glance at the silver and green nail from the image of the surveillance camera. Indeed, it had the imposing aura fitting to confront.

"...Oh?"

Continuing on fiddling with the computer, Trinity tilted her head in confusion.

Nine, who was picking up the scattered papers that were on top of a desk, turned around.

"What's the matter?"

"I was checking it up since it's been on my mind. As I thought, this room is odd."

The small magic circles that appeared on Trinity's fingertips were disappearing. He had to make sure again what he had seen just now.

"The data from this computer. The computer's clock. ...Not much time has passed since the day of the Black Beast's appearance~"

"The specific time?"

"...One year."

It was like only a year had passed in the room. Realistically, six years had passed since the appearance of Black Beast, but the time here had only passed a year.

"I see..."

While dropping her gaze to the documents she picked up, Nine muttered in displeasure. It seemed only Nine understood why the flow of time in this room was unusual.

Suddenly, Celica's behaviors made Ragna felt uneasy. Before he knew it, she had snatched the paper that had the diagram sketch from his hand. She had been staring it intensely for some time. She did it with enough enthusiasm to bore a hole in it.

When he looked at Nine, she was also staring with a grim face at the papers she had gathered up that was scattered on the floor before.

Ragna had a bad feeling.

"Celica?"

He softy called out to the tensed-up girl who was just beside him.

Celica's shoulders jumped as he did so. Then she looked at Ragna with such an anxiety that would make her tremble anytime soon.

"Ragna... This..."

"Something dangerous written here?"

Celica shook her head for so many times.

As if making sure of something unbelievable, she pointed at the writing that slanted upward badly as it went on, so bad you couldn't even pretend to say it was good. And then she gulped before starting to speak.

"This is... Father's handwriting."

In other words, Shuuichirou Ayatsuki's.

Someone whom Celica, Ragna, Mitsuyoshi, and Clavis had been seeking after.

Ragna's expression took a steep turn.

"You sure?" 

"Yeah. I don't have any doubt. I remember it very well."

Celica intensely stared at the diagram she held, but then also looked at it with affection. The footprints of the father she had been looking for were surely there.

Ragna once again looked up at the gigantic instrument which seemed like overlooking them. When he took a moment to observe the existence, he felt that its magnificence was overwhelming.

"Then, your old man created this?"

"At the very least, I think the design here was made by Father."

"So in the end, what's this thing? It's too fancy for an interior."

The ceiling above the silver and green nail was built exceptionally tall. The supporting chains were connected to several pulleys. When examined, they should be used to raise the nail even further up.

Celica took a glance at the diagram.

"It seems there's nothing written here that explains what it's for, but..."

Just as Celica was about to speak, a loud noise interrupted.

Everyone looked back all at once. Nine had read the documents that was scattered on a place separated from Ragna and Celica, also from Trinity. It was the sound of a bundle of papers thrown onto the measuring devices.

The five-centimeter thick documents she had collected hit the metallic box. Losing its strength, it once again scattered on the cold floor.

Nine stomped on the documents with all her strength. She put all the hatred from her heart.

"...Don't mess with me... JUST HOW ROTTEN IS YOUR MIND!!?"

Having been stomped with the sharp heel, one sheet was largely torn up. The panicked Celica tried to save the documents from her older sister's feet.

"Onee-chan, what are you doing!? These are Father's..."

"They are! That man undoubtedly wrote those! And also the blueprint and data containing the concept of that instrument! This is outrageous and no joke. No one but that man would construct such a ridiculous thing!"

"Hold on a moment. Tell me your reason properly. I'm completely clueless as to why you suddenly snapped."

Ragna forcedly interrupted both of them. He helped Celica, who had gathered the documents from the floor and held them to her chest, to stand.

In the meantime, Nine took a deep breath to adjust her breathing that was disturbed by her excessive anger. Even so, to vent her unsettled emotion, she struck the wall with her fist.

Worried, Trinity gently touched Nine's back. She took that chance to finally suppress her fury by biting her lips.

"...The Boundary is filled with the substance called seithr. The seithr was always overflowing continuously from that damned hole of a Cauldron. It's reasonable to think that the being from the Boundary called the Black Beast was also heavily influenced by the seithr."

"That information is extremely uncertain."

"It can't be helped. Nobody wants to get close to the Black Beast. And its remains that were left all over the place are not something you can carelessly approach."

To have one of the Ten Sages of the Mage’s Guild say that, he couldn't just easily dismiss it. What's more, many organizations had their hands full on dealing with the damages caused by Black Beast. They weren't in the position to just settle down and begin an investigation.

And then by not having any decisive ability to oppose the Black Beast, they would just be in disarray when facing another one of the Black Beast's destruction. The vicious cycle happened on a global scale, with its end yet to be seen.

"Let's get back to the topic. See, the Boundary and the Black Beast are like a mass of seithr. Then, this pretentious thing is... used to halt the flow of the seithr."

With a stern expression, Nine looked at the exceptionally fascinating artifact.

Some kind of unrest drifted from her narrative tone. Naturally, Ragna and Celica's faces stiffened in nervousness.

"What will happen when the seithr's flow gets stopped?"

"It's simple. Basically..."

Nine sluggishly opened her mouth to answer Ragna's question.

But as her words were on their way out, another voice followed on instead.

"Basically... We will be able to stop the activities of the Black Beast."

For some reason, a hoarse male's voice could be heard from the room's entrance that was left open until now.
