Sharlene has light blue hair and dark yellow eyes. Her hair is tied to her left by a blue headband (whereas Jillian's is teal and to the right) and some parts of her clothes are dark blue. Sharlene's expressions are more calmer than her sister; rather than a daring look she has a more laidback face. It can also be noted that she is scary when she gets mad.
In episode 101 in Leon's flashbacks, it shows that Sharlene and Jillian were friends with Leon and believes the legend of the Soryu child when Leon told them. She says she wants to see all kinds of things when she gets off the island, which proves that she might be an adventurous person. She also says she wants to eat a lot of delicious food, and added that 'Someday is one day, so...when?' which also implies that she is clueless. When Leon is recovered in Episode 104, she is shown that she is happy of the fact that the wind came back to Leon. She is also loyal to the Chief and Leon, and keeps trying to believe in the legend but slowly begins to doubts it.
