Eva is played by Evaluna Montaner, who also sings all of Eva's songs in both Spanish and Italian.
Eva is very smart and logical, just like her grandfather Manuel. She spends a lot of her time inventing apps for her phone, so when she jumps back to the 1950s, Eva has a hard time adjusting to a world without much technology.
"Eva is a typical 21st-century girl: totally dependent on her cell phone. She loves astronomy, physics, chemistry and app design. She is very intelligent, beautiful, modern and shy." — MundoNick.com
