Nico

Nico lives in an abandoned valley that is also called the "robot grave". Broken robots were brought there or in some cases even thrown away, even though they were still alive. Nico has set up a doll there that she adores and cares for. She has also planted flowers that she gives to everyone she meets in the valley. She always smiles, is extremely caring and therefore takes care of everyone. This is how Nico cleans a wound from Casshern, although Casshern assures her that his wounds will heal on their own. Nico seems to have experienced traumatic things in the past. She often doesn't know how to handle different situations and then just smiles. Generally she seems to live in her own world and all that is really important to her is her doll, which represents a certain person.
