"Dayo" is a heartwarming story of overcoming one's fear and triumphing over adversity. It centers on the 11-year-old Bubuy (voiced by Nash Aguas) who is out to save his abducted grandparents in the land of Elementalia, a magical and mystical world that houses many of the Philippines' mythical creatures and other enchanted elements. Along the way, Bubuy meets Anna Manananggirl (voiced by Katrina Legaspi), a teen manananggal (a winged creature that can separate her torso from her lower body) who befriends and helps Bubuy in his quest to rescue his grandparents.
