What? Are you saying that my dad is the one responsible for building Core Blaze......? Why? How?
(As Dida pretended to calm down, I brought up the possibility that Core Blaze might be controlled by someone)

(Dida seemed to have someone in mind, as he bit his lips and put his sword away.)
............Okay... I have a feeling this is something you must know.

Back in 2093, Core Blaze is created as a symbol of peace. As you stated, my dad was responsible for building this robot.
Marr and I had been entering my dad's lab from an early age. As I grew up watching Core Blaze, I felt ecstatic when it was finally released, as if I built that thing myself. (Dida flashed a faint smile, reminiscing on the past he clearly misses dearly).

Core Blaze was fed with data such as the standard of peace, the current problems of Zipangu, and other forms of unbiased data. From there, to better understand the situation, Core Blaze allowed itself access to all kinds of machines and devices for further information.

In the eyes of Marr, Core Blaze probably looked awesome. Marr knew Core Blaze had an ability to conversate, so she kept on talking to it.

To make sure that no third person enters an incorrect information, only a select few individuals had access to Core Blaze's knowledge. Of course, Marr and myself did not have such rights.

But I am sure Core Blaze noticed that the concept of peace that was instilled in it was being related to others, in its daily conversation with young Marr. Once it realized its own identity, it really began to enjoy its conversation with Marr.
It was as if it believed that Marr's words were Zipangu's words as a whole.

(Come to think of it, I didn't ask what Marr was up to these days. When I asked Dida of Marr's whereabouts, his face turned to ashes)
......Marr......

...Marr is currently in coma.

Back in 2097, 2 years after the army helped us, Marr was stricken with a disease caused by pollution, and fell into a deep coma, which is where she is right now.

And...Marr's life support is...
Core Blaze.

...It was what Core Blaze wanted itself.
A sense of responsibility for her life, and
the desire to eliminate the cause of pollution, so the doctors can diagnose Marr's illness, and ultimately snap her out of the coma. Two months later, that's when all hell broke loose for Core Blaze.

It probably noticed it firsthand that one of the main reasons for pollution was the rapid ascend in the field of IT. And the fact that eventhough the residents of Zipangu knew deep down that the field was causing pollution, they never really provided a solution to remedy the problem.
That's when Core Blaze made the decision...

The decision to eliminate Zipangu as a whole.

It's hard to determine whether this is real or not, since it's my opinion based on what I saw the past few years. I can also say that there's no other plausible cause for this sudden change of events.
The so-called experts provide various problems and explanations for this mess, but... they were all covered during the development stage of the robot, and I believe those were all effective.

...Marr can be currently found at Roppongi Mall, the enemy headquarters. I plan on heading there right now... to rescue Marr.
(Dida is heading towards Roppongi. What should I do? Should I report this to Asia...?)

(I bid adieu to Dida and returned to Asia)

(Should I gather up more information on this matter...?)

...What is it? Have you found some new information on this?
(Asia came to me excited, so I told her everything I heard from Dida)
