In episodes 1 and 2, we're shown that part of Tokyo is sealed off. In episode
2, after Oubu knocks Entei into the air, we get what I presume to be an aerial
view of the region (enclosed by a circular wall):

In episode 1, we see Kinoa and Shizuru beat up two people who appear to be
guarding an entrance to the region. The character in red at the top of the
tower in the top-center is 封, meaning roughly "seal" (as in "isolate").

Shortly after that, a man notifies Reoko that "A Bubuki user has broken
through the gate". Upon hearing this, Reoko gets up and leaves the memorial
ceremony she's at.

What is actually in the sealed region? I'm pretty sure the "Buranki prison"
(i.e. the place where Oubu's skeleton is kept) is in there, but the region
seems far larger than it needs to be just to accomodate the "prison". As
you'll note if you look closely at the aerial view above, the streets inside
the region are laid out in a very "honeycomb"-like manner, while the streets
outside the region are gridded, much like real-life Tokyo. What's the deal
with that?

Why is part of Tokyo sealed off?
