Miya has the general appearance of a Nāga, having the lower body of a white serpent and the upper body of a woman. She had short blonde hair, an ample bosom, blue eyes and wore blue lipstick. She wore a frilled purple blouse, also had a tattoo on her left shoulder and was generally seen sucking on a lollipop.
She seemed very confident and flirted with Khun on multiple occasions.
As Khun, in his Mr. Mask disguise, was replaying the footage of the Team Mad Dog vs Team FUG semi-final, Miya appeared behind him and revealed that she knew it was him before telling him that she, and two other gamblers, was planted by FUG to control the Battle and take down Viole's old teammates. To that end, she led a team known as "Team Snake", hiring Macha, Paul Belkrohn and another Regular to fight for her.
