Hanako

花子

Lindabrea is a dragon and the heir to a noble family. Dissatisfied with having only orc meat to eat, she leaves her menacing-looking castle to roam the world in search of more delicious food. Lindabrea is accompanied by her vampire maid, Carmilla, whom she recognizes as "useless" (i.e., not very strong or apt in battle) but appreciates for her loyalty.
Joanna regards Lindabrea as a rival out of jealousy that Lindabrea seems to win battles effortlessly, while Joanna struggles and trains hard; Lindabrea, however, doesn't seem to pay Joanna too much attention, usually being distracted by food while Joanna is talking to her.
Since her name is too long and complicated for him to pronounce, Genzou nicknames her "Hanako".
