Lizzy is very dirty-minded and perverted. She likes seducing people (boys, to be specific) and stealing their virginity. She's also very honest and says whatever is on her mind. She sees herself as superior to others. She's also very confident about her body.
The 2 of them are sisters, Lizzy thinks Kuru is as innocent as a baby. Lizzy and Kuru are actually very close and often hangout together. They usually go out in public and try to flirt with people for fun. Lizzy sometimes teases Kuru for fun too.
Lizzy and Giro don't really talk much nor hangout with each other much. They both have a neutral opinion on each other. Lizzy doesn't really care too much for Giro despite them being sisters.
The 2 of them are polar opposites. Lizzy sees Lizzy-chan as a complete child because of her pigtails and fashion taste. Despite being polar opposites, the 2 of them get along well.
