The madness taking place right now is—

—due to a massive emission of energy that burst forth from another world adjacent to ours having triggered a contact abnormality between world lines.

In the instant before the Heroic Spirits materialized, having been summoned in that other world—

—things got all tangled up in such a way they were redirected into our world line, one with a worldview entirely incompatible with theirs.

Hey.
Explosions sure are deeply profound, don'tcha think?

......

Aw, don't say that.

... Oh.
You're wondering why I know all of this, are you?

When my consciousness got blown away in that explosion, in that moment—

—there was this guy who taught me all sorts of things in a dream.

He was kind of like this, I think.

......

You've got some pretty harsh riposte today, don'tcha.
