Oumiya Emma (大宮えま) is an independent female Virtual YouTuber. She can speak English, Bahasa Malaysia and Bahasa Indonesia as well.
She debuted as member CyberLive's 2nd Generation CyberAlter alongside Kurohana Inori, Iekushi Chapipi, Alchemilla Menace, and Inami Yoki.

Once upon a time, there was a beautiful angel who lived in heaven. Her job was to protect the people of Alteria from wrongders. But one day she was banished for protecting a child - who had murdered his abusive parents. The angel believed that what the boy had done was justified... But the Coucil of Heavens did not agree whith her. They broke her wings. The angel fell into despair and was consumed by sadness - she was miserable and living in denial. Her unstable emotions caused her to transform into a demon. The Coucil decided to keep her chained deep inside a dungeon cave to prevent her transformation. This angel is now known to all as Oumiya Emma: the final dungeon boss that haunts Alteria's peace, still targeted by adventurers to this day.
