Eve Belmont

Eva Belmont is a minor antagonist and eventually core ally in Pretty Cure Monster Mania. Initially appearing as the sole librarian of the Lucky Library, though she eventually reveals herself as a Monster Hunter who is determined on cleansing the world of monsters. Including the Precure, since technically they're monsters too...

In the last arc, she reluctantly begins to work together with them to save the world. Using her talent with her personal weapon, her whip, and her outstanding knowledge about all types of monsters and their weaknesses to aid the Cures during their most challenging battles.

Personality
Eve is a textbook example of a strict librarian. Uptight, quiet and always demanding silence. She almost always sits behind her desk in the shadows and has a 'talent' to throw books into the right shelf from her desk. Eve is a serious woman with no-nonsense type of personality, preferring to keep personal feelings from her work and thus can be very cold at times.

Being a Monster Hunter, it's no secret that she despises Monsters. Though her main beef seems to be with vampires, claiming that they're the worst and most dangerous.

Trivia

 * Eve was actually born in England and started travelling around when she became a Monster Hunter. She decided to stay in Seinarushima many years ago when she realised that the gate to the monster world was here.
 * She also has a heavy accent, which Yuina has trouble understanding sometimes.
 * Eve Belmont is a big walking reference to the Castlevania (Akumajō Dracula) video game series. Being a monster hunter, carrying a whip as her main weapon and various other weapons and relics to help destroy monsters. Her big hatred for vampires is a subtle reference to Dracula being the main villain in (most) of the games. But her surname is the force that drives it all home.
