business in Shibuya in advance like I suggested? ;)

Navigate the shifting Amara Network in Shin Megami Tensei III: Nocturne HD Remaster. Learn how to find exits, communicate with Hijiri, and deal with Spectre.

Oops. Looks like Hijiri messed up. Wherever you are, it's decidedly not Ginza.

Hijiri talks to you via the Terminal--he tells you that the teleport screwed up and dumped you directly into the Amara Network. He tells you to look for an exit.

At one point in the dungeon you will find an exit, which closes up as soon as you approach it. Hijiri asks you if your path has been shut off. Say yes, and he decides to test something. After the test, he tells you it turns out that the Amara Network's structure is not set, and that it constantly changes. On the next floor the network pulls the same crap and Hijiri tries to change it to open your path, but the method he uses to contact you warps too and he goes bye-bye.

Further in on B2F, there's a room where the area is stable enough to communicate with Hijiri. Talk to him there and he can reopen the staircase. He says from now on, go to any of these "thin spaces" to tell him about something that needs fixing.

As soon as you enter B1, several exits disappear. A Shinentai in here will says the red garbage you see on the floor is pure Magatsuhi. It also goes on to tell you that Magatsuhi is born from strong emotions.

The central room to far east is the "thin space" on this floor. As soon as you enter to contact him, Hijiri reopens the north and south staircases. He also tells you that someone is trying to break into your communications.

The north exit leads straight to the final area of the Amara Network. Through the south exit, you will find a Shinentai of a young boy--ignore him. He tells you to go right, then left--a different thing each time--to confuse you. The path on the right leads to the area you would have gone to if you had taken the north exit. The path to the left leads to a long loop with some treasure boxes.

Go through the north exit. In the "thin space" room in that area someone interrupts Hijiri as you're contacting him, and Spectre pops up. Spectre is really annoyed at your communication with Hijiri as they are disturbing it. It thinks you want to kill him and take all the Magatsuhi here. It asks if the Magatsuhi is what you are after. If you say no, it doesn't believe you and boots you out of the room. If you say yes, it attacks!
