Spoiler:

Who is 080? Are you talking about Adam C.? She was the successor to Adam Neuschwanstein who was considered an experimental failure. Her mission was to locate and retrieve Adam Neuschwanstein. As for why shes with the sound boy, its probably just working undercover. The sound boy was shocked at her identity. Interestingly, she could also learn her opponent's abilities. Her combat abilities are superior to Adam Neuschwanstein, but was defeated by the sound and her own ability.

Then again, meeting Adam Neuschwanstein was a coincidence. She claims her other tasks were to collect various Needless DNA to create an all-powerful "magician" (!?) .

*update*

Oh I get it. its the number on her collar.
