Laboring over an experiment, Casey complains to Pipira about the fruitlessness of her endeavor.  Pipira surprises Casey by suddenly making a brilliant suggestion.  Casey becomes convinced that Pipira is hiding something and when she confronts the girl about it, Pipira responds by slicing her arm open and showing Casey her insides.  Casey flips out and flees rather quickly.

Over the course of the next week, Cecilia continues to meet Pipira and Sito on the roof and the three become very good friends.  However, also during the week Sito and Khann continue to get into a series of fights and arguments, culminating on the roof.  Khann taunts Sito and Cecilia a little which sends Sito over the edge.  Though Sito manages to slice open Khann’s back, he soon discovers that Khann’s insides are nothing but fire and lava and neither of them really have an advantage.  Eventually Khann tackles Sito, causing his sword to soar out of his hand.  The blade flies right at Pipira, slicing her arm clean off.  Instead of blood coming out, however, a thick purple liquid and an assortment of nuts and bolts fall from her severed limb, which lands with a very metallic thud on the rooftop.

Both Khann and Sito are shocked but Khann manages to keep his head enough to burn the end of her shoulder to keep any more of the purple goo from coming out, which seems to be the source of Pipira’s sudden panic.  After calming down she explains very briefly that she is a robot before running off to find a few to re-attach her arm.

Pipira eventually finds Casey and enlists her help in reattaching her arm, which turns out to be a very simple process, it was only a matter of finding someone to hold the limb still.  Pipira explains to Casey (in her own roundabout way) her rather peculiar history during the process.  While she is delighted to have two hands again, Casey seems in general very disturbed about the whole ordeal.  She apologizes for her display earlier and promises that she'll eventually adjust to this startling new information.
