Luna

She is noted to be self-absorbed, yet seems somewhat emotionless. She claims to be a scholar, coming to the Venus Islands to discover its secrets, although it's uncertain whether this is true or whether she is really just there for the roasted sweet potatoes, her favorite food, which she implies is because they give her fond memories of her time with her grandfather in her home country. Besides her love of roasted sweet potatoes, she is also implied in her character episodes and first birthday episode to have a large appetite.
