Serafall Leviathan

Serafall Leviathan (formerly Serafall Sitri) is one of the Four Great Satans in High School DxD, holding the title of Leviathan and formerly serving as the Satan in charge of foreign affairs.

She is the older sister of Sona Sitri (from the Sitri Clan) and has a very deep sister complex toward her.

Appearance: She looks like a beautiful young woman in her late teens, with long black hair in twin tails, blue eyes (often depicted as violet/pink in the anime), a petite/childlike build, but with notably large breasts. She frequently wears a magical girl outfit (complete with a wand), inspired by her obsession with magical girl anime, which earns her the playful nickname "Satan Girl" or "Levia-tan" from herself and others.

Personality: In stark contrast to her serious younger sister Sona, Serafall is extremely cheerful, bubbly, friendly, and has a very childlike, playful demeanor. She often ends sentences with ☆ stars, calls people cute nicknames like "So-tan" for Sona or "Sirzechs-chan," and is heavily fixated on magical girl themes. Despite her goofy and carefree side, she is also a powerful, capable, and selfless Devil when the situation demands it.

She's one of the strongest female Devils in the series and a fan-favorite for her energetic, over-the-top personality!
