Senritsu

Senritsu, known as Melody in the Viz Media translation, is a Music Hunter, named for her skill with instruments. Senritsu is a Music Hunter and is the kind and understanding member of Neon's bodyguards. She is always ready to listen to anyone's confessions and has the gift to make people open up to her. As Leorio notes, she is one of the very few characters who has made Kurapika open up to her.
