Claudia is a resident of Soleanna in Sonic the Hedgehog (2006). She is the owner of a store within the shopping district of Soleanna New City and can often be found near the mall area. She is apparently quite protective and reliant on her shop, and she implies that it is partially run by someone else.
In Shadow's story, Claudia gives Shadow his first Town Mission. All of a sudden, Iblis and Mephiles' minions have appeared in Soleanna New City's shopping street and are terrorizing the citizens. Fearing for the safety of her shop, Claudia gives Shadow the task of saving the street by defeating these monsters.
