Serafall Leviathan

Serafall Leviathan (セラフォルー・レヴィアタン, Seraforū Reviatan), formerly known as Serafall Sitri (セラフォルー・シトリー, Seraforū Shitorī), is the Satan Leviathan who formerly oversaw Foreign Affairs prior to the events of 666. She is the former heiress of the Sitri Clan, the eldest daughter of Lord and Lady Sitri, and the older sister of Sona Sitri. In contrast to her serious and disciplined younger sister, Serafall has a cheerful, friendly, and highly expressive personality. She often behaves in a childlike manner, affectionately addressing Sona with nicknames such as “Sona-chan” or “So-tan,” and calling close acquaintances like Sirzechs by similarly playful names. Her speech patterns and mannerisms further emphasize this youthful disposition. Serafall has an intense fascination with magical girls, which she embraces openly as a hobby. This interest extends to cosplaying and even participating in human-world auditions related to magical girl media. Although she was initially unsure about having siblings, she developed a strong attachment to Sona after her birth, becoming extremely doting and occasionally placing her sister in awkward or embarrassing situations due to her enthusiasm. Despite her lighthearted and playful nature, Serafall is also capable of great resolve and selflessness. She took part in the prolonged battle against Trihexa and deliberately chose not to say farewell to her sister, fearing that seeing Sona cry would cause her to hesitate. This decision highlights her deep sense of responsibility and determination beneath her outwardly carefree demeanor.
