Serafall Leviathan

Serafall Leviathan, formerly known as Serafall Sitri, was the Satan Leviathan who was in charge of Foreign Affairs, prior to the events of 666. She is the former heiress of the Sitri Clan and the eldest daughter of Lord and Lady Sitri, and the older sister of Sona Sitri. Serafall is a beautiful girl; looking in her late teens with black hair, tied into twin tails and blue eyes (Pink in season 2-3). She also has a child-like body (albeit with large breasts). Her body measurements are [B85-W56-H80 cm]; height is 160 cm and body weight is [48 kg]. She usually dresses in magical girl's clothing (from Magical Girl Milky Spiral Seven, the same outfit Mil-tan wears), magic wand and all, prompting Issei to call her the nickname "Satan Girl". Unlike her serious younger sister, Serafall is cheerful and possesses a childlike personality, which is evidenced when she addresses her sister as "Sona-chan" or "So-tan" and Sirzechs as "Sirzechs-chan". Adding to her childlike personality is the fact that most of her lines end with a star. She also has a deep sister complex, and has a tendency to get her sister into embarrassing situations. Despite her childlike nature, Serafall can also be selfless and determined, as she joined the neverending battle against Trihexa and resolved not to bid farewell to her beloved sister as she is afraid of hesitating if she saw Sona cry.
