Who is the boy in the coffin that wakes up in the last episode of the second
season, _Gemini of the Meteor_? What significance does he play? Why does he
look like Yin?

If it's sticking vaguely close to the manga it's Kagutsuchi (the being
unknown) who is created when Izanami (Yin) and Izanagi (Hei or Shion) bond as
predicted in the [Mikata
Documents](http://darkerthanblack.wikia.com/wiki/Mikata_Documents).

> Izanagi gazes upon the false sea bottom, waiting for Izanami. Izanami will
> cross the sea bottom and eventually the two will meet. When they do, heaven
> and earth will split in two, and there the Gate of Hell will open. From the
> Gate will come forth one, a being unknown. And strife will continue for
> eternity.
