Armaiti (アールマティ, Ārumati)? is a demon in the series.
Armaiti ("beneficent devotion") is one of the Amesha Spentas in Zoroastrianism. She is the personification of holy devotion, the daughter of the creator, Ahura Mazda, and represents righteous obedience. She is associated with the earth and in that capacity she is the goddess of fertility and the dead, who are buried in the earth. The fifth day of every month and the twelfth month are dedicated to her. Her eternal opponent is the archdemon of discontent, Nanghaithya.
"A female angel of Zoroastrianism and one of the Amesha Spenta. She is the daughter of the head god Ahura Mazda and sits in his left hand. Armaiti is roughly translated as "devotion", and she is the personification of piety. It hurts her consciousness when a guilty person walks by, but she rejoices when people are feeding their animals or obeying the heavens. Her rivals include Taromaiti."

Armaiti in Card Summoner
In the English version of the PSP port of Persona 2: Innocent Sin, Armaiti is mistakenly referred as a male in her profile. In the original version of the game, her profile explicitly says that she is the daughter of Ahura Mazda. Her PSP profile removes the reference to her father and never states her gender, which led to the confusion.
