Serafall Leviathan
Serafall Leviathan, formerly known as Serafall Sitri, is the current Satan with the title of "Leviathan" and Sona Sitri's older sister. She is the Satan in charge of foreign affairs.
Appearance
Serafall is a beautiful girl with long, black hair tied in twin
ponytails and blue eyes. She also has a child-like body (albeit with big
breasts) and 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 coin her the nickname "Satan Girl" (魔王少女 MaŌ Shōjo).
Personality
Unlike her serious younger sister, Serafall has a childlike personality,
which is evidenced when she calls her sister "Sona-chan" and "So-tan"
and Sirzechs
"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 embarrasing situations.
Michael
Michael is the leader of the Angels
and Seraph. He is the only Archangel and the original God's very first
creation who took His place as leader after He died in the war. His
current goals are to recreate the lost members of the Heavens (mainly
the Seraphim) and guide the Church with God's teachings.
Appearance
Like Azazel,
he has twelve wings growing from his back, and unlike other Angels
whose wings are white, his wings are colored gold, further symbolizing
his position as the leader.
Personality
Michael in his few appearances has seemed kind and compassionate.
However, he will put the good of the many above the good of the few, as
shown when he allowed Asia to be banished in order to preserve the faith of the people and not risk the safety of Heaven.
