Derieri's Sister is a member of the Demon Clan.

Appearance
Derieri's sister has short and messy hair. Her demon mark is shaped like a crescent on her right eye and a small mark under her left eye. Unlike Derieri, she wore clothes. However, it is seen that she uses her darkness to cover her crotch. She's somewhat muscular and has a good figure.

Personality
Little is known about her personality, but according to Derieri, she had feelings for Monspeet.

3000 years ago
During the Holy War, she was one of the many demons that Ludociel kidnapped and locked inside his giant Ark to use as sebum to lure the Ten Commandments to the Fairy King's Forest and eliminate them. When the Commandments and an army of Demons fall into the trap, the hostages are killed in front of their people. Before dying, she calls her sister, leaving Derieri in shock to see her die.

Derieri
It is not clear what kind of relationship she had with her younger sister, but it seems that they cared a lot about each other. Her death provoked in Derieri a hatred for the Goddess Clan that remains to this day.

Monspeet
According to Derieri, she was always in love with Monspeet. What the latter felt for her is unknown.
