If I had to choose an anime character to come over and eat dinner with me it would have to be Mirajane Strauss. She was Fairy Tail's main cook for awhile and could definitely help me out in the kitchen should the need rise. Not only that she's beautiful, a fighter, but also has a sweet personality (just don't piss her off). No doubt she would make for great company.
I feel like we would have lots to talk about; especially with her being in Fairy Tail... She could dish out some juicy gossip about the members😉.
