ラルファ

Larfa is this game’s main heroine, the alien trying to make Yuusaku her wife. She is the daughter of a space overlord and extraordinarily beautiful. Her breasts are on the large side and her bangs are actually antennae that form a heart-shape when she sees someone compatible and move to reflect her emotions. She is madly in love with Yuusaku and thinks about nothing but him. She is bright, simple, and straightforward. She’s also the type who becomes inflexible and loses sight of her surroundings once she makes a decision. This flaw is why some consider her a troublemaker. After seeing Yuusaku’s porn, she comes to believe that what she saw was normal for Earthlings. She possesses a bracelet with several functions such as instant costume change, short-range teleportation, and the ability to create a small space that the wearer imagines, as well as several other sex toys made from their advanced technology.
