Editing Hagure Yuusha no Aesthetica:Volume 7 Epilogue (section)

===Part 1===

Occasionally a muffled noise was heard ringing throughout this place.
 
The deep bass sound could turn your stomach.
 
With each step it seemed like time slowed down.
 
"What the....."
 
While walking in the dim light of the passage a red light illuminated, Onizuka Kenya tried to cover up his astonishment.
 
Right now he was at the lowest level of JPN Babel.
 
It was late at night, however he was still on campus headed towards the high-rise of Babel.
 
The soaring building was very eye-catching, but the underground -- were also a number of basements that all the staff and students were aware of.
 
And ......
 
The lower most floor supported all of the tower of Babel, also it symbolized the authority of the COCOON. This wasn't simply referring to the structure of the building, the fact was the lowest floor in Babel was top secret.
 
However, those were all just rumors, not one person had seen it with their own eyes.
 
He was in the middle of shopping at the supermarket, until Tiana urgently left because of an important matter.
 
To put his mind at ease a little Onizuka decided to accompany her, which was why he was walking through this forbidden place.
 
"Well..... Ken-chan is just an ordinary student, so it is normal for you not to know."
 
Tiana was walking one step ahead Onizuka as she spoke to him without looking back.
 
"Whether it's the massive data "Apocalypse" server, the boundary system that covers the majority of the campus, the electricity and water circulation system, and the basic life support/ environmental program, all of these were in one place the so-called "Babel system". You could say this place is like the heart of Babel."
 
She took a breath.
 
"Well...... to be accurate it's right above the heart. Only members of COCOON, who are responsible for each Babel, can enter the "Babel system" the lowest floor in the tower. But before entering, you must pass through the strict biometrics as well as the magic certification to enter the basement. It seems that Tsusukara was the only person in COCOON to pass through the biometrics authentication."
 
"......'It seems'?"
 
Hearing Onizuka question, Tiana looked over her shoulder.
 
With a wry smile on her face,
 
"That is what I had heard. But then again, Tsusukara died during his tenure with COCOON while in charge of Babel, so......"
 
COCOON was comprised of the world's most powerful people, and the sky high tower of Babel was its symbol.
 
If COCOON was destroyed, there grand principles would be shattered.
 
In order to harmonies the world as well as management it, COCOON and Babel must always be at their strongest.
 
Onizuka then suddenly remembered something.
 
"Then what about the server rooms and control rooms above ground?"
 
Onizuka had once altered the training program leading to the incident in the arena with the control room in its warehouse.  
 
If what Tiana said was correct, then there you can control all of the systems. Also if the security program detected the strange operation it should have been also possible to prevent beforehand. Looking at it from the public safety perspective, there should have been no reason the incident should of been able to occur. Even from the technical side there was no problem. The boundary system that changes psychical damage to mental damage was many times more complex.
 
"That was merely the operating or control system for that one place."
 
Tiana answered.
 
"As for here, its more like the "power reactor" for all of systems. But they needs engineers and school personnel other than the COCOON to actually operate the systems. Naturally they can not enter the lowest floor, so they need other places to control the systems. Otherwise each operating system must be controlled by COCOON personally, which would take a long time and be way too troublesome."
 
"..........."
 
Tiana's "power reactor" analogy, allowed Onizuka to immediately understand the difference between the two.
 
During the training program incident, Onizuka changed the level of the program. And then the terrorist Tanaka changed the intensity of the program making it go berserk. The level and the intensity change were all done above ground.
 
As for the ranking tournament intrusion the other day, when the self proclaimed "Hero" destroyed the boundary system Babel's engineers repaired it. They were able to restore the system because only the above ground system was destroyed and its cable was cut from the system going into the ground. The "power reactor" remained intact.
 
Onizuka then voiced his only remaining question -- the most pivotal problem.
 
"...... Since Babel's students and faculty are forbidden from entering the top secret area. Then how come an outsider thinks it will be a breeze to walk right in?"
 
More importantly --
 
"What on earth are you planning on doing, Tiana?"
