Its body is a bloated corpse; its head a grinning skull. And it is massive—many times the size of
a human. The head lolls from side to side as it tromps about the room on all fours, bringing to
mind the wild maneuverings of some wretched, starving beast. This creature—this
thing—is Experimental Weapon Number 6.

Also known as "Halua".

Emil resumes walking, using the sound of the distant voice to guide him. Almost as if it was calling
him home...

By the time Emil reaches the third level, he is moving on memory as much as sound. His hands
and face are covered in fresh wounds from numerous falls, but every time he thinks about giving
up, his mind returns to... his sister.
We studied together.
We ate cookies together.
We cried together.
We laughed together.
...And sometimes I was the only one who got yelled at.

That's why I was never lonely. Our being together allowed me to stay strong.

Is she... worried about me? Or is she coming to kill me?

Emil feels prepared to accept either outcome. After all, this was his older sister—the person he
loved more than anyone else in the world.

"Halua, I..."

The moment Emil speaks, Number 6 comes to a sudden halt.

Silence descends on the chamber as the siblings stare at each other.
"I'm sorry, Halua. But everyone says you're too powerful. They say it's too dangerous unless I seal
you away. I'm so sorry."
As Emil watches her body begin to turn to stone once more, Number 6 simply waits in utter,
perfect silence.

The moment Number 6's petrification is complete, her memories flood into Emil's mind.
The two of them huddling together in the cold. All alone in the world, with no one to protect them.
All she wanted was to save her little brother.

And yet, it was that little brother who, in a sense, saved her.

It was our combined power that destroyed The Aerie. Whole existences. Entire lives. Even
their memories. We took it all. We took EVERYTHING.
My sweet, gentle sister turned into a monster. And the same thing will happen to me, now that I
have her power.
If my instincts as a weapon win out and destroy me in the process... If that power ends up
hurting someone I love... I...
