A character from GALZOO Island, who serves as Leopold Maala's arch-rival and adoptive sister.
Throughout the game, she will attempt to capture and tame any Gal Monsters not captured by Leopold, and will succeed in doing so if Leopold takes too long. To illustrate this, she is always guaranteed to capture and tame a Tenten, who becomes her accomplace.
Additionally, Erina also makes a cameo in Sengoku Rance, serving as a bonus unit after completing the game once.
