So how was battling against Dunas... ...!?
(I reported to Asia everything, from defeating Dunas, to Dunas somehow finding a way to acquire the operational unit.)

...Is that so...? Dunas getting his hands on the operational unit...? But why... and how did he do that in the first place?

(He remained silent for a bit, then shakes his head in bewilderment)...I'm sorry. I really do not have any clue where this is going.
(As soon as Asia mentioned that, Kamuna violently shook again)
No way...!

(Asia hurriedly brought out the copy of Acacia Chronicle, and started reading.)
......This finally means Core Blaze has begun to move.

Core Blaze is a name for the AI that caused the destruction of Zipangu. It was initially built as a sign of peace for this area, but over time, these AI robots begun to recognize acknowledge their own self, and soon they revolted against people. That Core Blaze is now on the move.

The moment Core Blaze was created, it was set up at the tallest buliding of Roppongi, Roppongi Mall. That spot is currently served as home to Core Blaze, the army of robots. I think that's where Core Blaze began to lose itself. Now we really don't have much time.

In any case, for soundly defeating Dunas, its memories are currently on the way back to the grasp of barrier it was initially set in. The preparations for the binding spell is complete. Once the time is right, I will start the spell of re-bounding Dunas's spirit. In the mean time, I want you to immediately defeat Core Blaze...!

Thank you. In year 2102, Roppongi Mall serves as the enemy headquarters, which means we can't just go in there ourselves. I advise you to head over to that era, and enter the mall through an underground path.
Since the mall is the headquarters, you may encounter a number of monsters you wil have never seen. None of them should ever be underestimated. Good luck!

As long as Core Blaze roams around, the destruction of Zipangu is inevitable!

(I re-entered Shibuya of 2102. What I see down there is... Dida!)
......You are......!

...Ah, so you're sent here to defeat Core Blaze. Seriously, I'm so sorry...
(As he uttered those words, Dida couldn't bear looking at me in the eye)

The enemy headquarters is located at the center of Roppongi, at Roppongi Mall. Of course, you won't be able to enter the fight face-on. At the main lobby, an army of robots called Imperial Guard stand by, serving as security. Your first task is to enter the building wile faking those robots out.
(As he mentioned these, Dida handed me a single copy of globe.)

The truth is, there have been underground pathways that leads from Shibuya to Roppongi Mall. Using this will allow you to enter the building without being noticed by Imperial Guard. This is the map that'll lead you to there. It's just a straight line, so you should have no trouble entering there, but I'll give you the map nontheless.
