Merle is a recurring supporting character in The Vision Of Escaflowne.
She is a childhood friend of Van Fanel, whom she very clearly is in love
with. In turn she is often clingy, bratty, childish and overall acts in
a way not too surprising from her cat-like demeanor, although she does
tend to have good intentions. She has an odd love-hate relationship with
Hitomi due to Van's feelings for her.
In the 2000-2002 Bandai Entertainment Dub of both the original series
and the Movie, she is voiced by Jocelyn Loewen. For Funimation's 2016
Redub of both products, he is instead voiced by Alexis Tipton.
