Serafall Leviathan

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].

Due to her hobby and interest in magical girls, she like to dress in magical girl's clothing (notably from Sailor Moon, specifically Sailor Venus and even Mars on occasion) prompting Issei to call her the nickname "Satan Girl" (魔王少女 Maō Shōjo). Outside of her hobby, Serafall would wear cute clothes that show off her petite yet busty figure and she loves the color pink, white, red and black for her clothes.

And unlike her serious younger sister, Serafall is cheerful, friendly and possesses a childlike personality, which is evidenced when she addresses her sister as "Sona-chan" or "So-tan" and her close friends such as Sirzechs as "Sirzechs-chan". Adding to her childlike personality is the fact that most of her lines end with a star and her intense fascination with magical girls, which she took to cosplaying as a magical girl as a hobby even audition in the human world for a live-action film adaptation for Sailor Moon R. She also has a deep sister complex which she developed after Sona was born as she excessively doted on her younger sister, and has a tendency to get her 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. Lastly, she adores any chance she can get to live life as a normal girl while also dreaming to be a cute wife; and if her lover wants, she isn't afraid to look and act sexy... she'll even wear lewd and revealing outfits and she definitely will do anything for them no matter what!
