Background
She's the daughter of that lawyer who showed up in the final episode of the anime. Her home life is pretty isolated—her mom works late shifts, so she's usually alone, and she barely sees her father, let alone talks to him much.
Personality
She's got a clear tsundere streak, especially when dealing with her dad. That defensive, hot-and-cold thing comes through pretty strongly in their early interactions.
