Lindabrea is a dragon and heir to a noble family who got tired of eating nothing but orc meat in her gloomy castle, so she set out to explore the world and find better food. She travels with Carmilla, her vampire maid, who she openly admits isn't much of a fighter but sticks with her out of sheer loyalty—which Lindabrea appreciates.
Joanna sees Lindabrea as a rival, mostly because she's bitter that Lindabrea wins fights so easily while she has to struggle and train constantly. The thing is, Lindabrea barely notices Joanna's rivalry—she's usually too focused on whatever she's eating or thinking about eating to pay much attention when Joanna tries to talk to her.
Genzou can't be bothered to pronounce her actual name, so he just calls her "Hanako" instead.
