Ame no Uzume is the goddess of dawn and revelry in the Shinto religion of Japan. She famously relates to the tale of the missing sun deity, Amaterasu.
Amaterasu's brother, the storm god Susano-o, had vandalized her sacred buildings and brutally killed one of her maidens because she refused to trust him. In turn, Amaterasu became terrified of his wrath and retreated into a cave. The world, without the illumination of the sun, became dark and the gods could not lure Amaterasu out of her hiding place.
The clever Uzume overturned a tub near the cave entrance and began a dance on it, tearing off her clothing in front of the other deities. They considered this so comical that they laughed heartily at the sight.
Amaterasu heard them, and peered out to see what all the fuss was about. When she opened the cave, she saw her glorious reflection in a mirror which Uzume had placed on a tree, and slowly emerged from her hiding spot.
At that moment, the god Ame-no-Tajikarawo dashed forth and closed the cave behind her, refusing to budge so that she could no longer retreat. Another god tied a magic rope across the entrance. The deities Ame-no-Koyane and Ame-no-Futodama then asked Amaterasu to rejoin the divine. She agreed, and light was restored to the earth.
"Origin: Japan. The goddess of god-entertaining. She famously danced to lure and angry Amaterasu out form hiding in the Ama-no-Iwato cave. She also danced before the unexpected guest Sarutahiko in the Tenson Korurin."
—Shin Megami Tensei A-Mode DDS dictionary
Like Divine race demons, Megami are not actually weak to Sword attacks, but take normal damage from them and resist everything else, making them only weak to Sword by comparison.
Shin Megami Tensei III: Nocturne
"Her full name is Ame-no-Uzume, meaning 'the terrifying female of heaven'. She is famous for luring Amaterasu out of hiding with her seductive dancing. Her husband is Sarutahiko."
—Shin Megami Tensei III: Nocturne compendium
Ame no Uzume was shortened to Uzume. If the Demi-fiend allows her to talk with Sarutahiko, her mythic consort, in a random battle, they will start a one-off special conversation, and Sarutahiko will eventually offer her an emerald (symbol of marriage) and leave. Uzume is the lowest-level member of the Megami clan obtainable by the Demi-fiend, and is needed to obtain Amaterasu in the Cathedral of Shadows through a sacrificial fusion between Yatagarasu and Take-Mikazuchi with her as the sacrifice.
