Yu-Da is the main male character in Young-You Lee's Moon Boy series. He is the Black Rabbit.
Yu-Da has spikey black hair with dark brown eyes that turn red at night. He is often seen wearing a small tassle-like charm in his hair.
Yu-Da appeares to have two personalities. One is very kind and acknowledging. The other is very dark, unkind, and focused. The truth is he fears trust above all else causing him to act drastically.
