Marie Nobi is a student in JIOR.
She was a former test pilot, the guinea pig for the Valvrave project. Due to her body not fit enough to provide Runes to Pino, she was rejected from the program. She became a student since Pino had ate all of her memories.
Marie Nobi is created by Sunrise and originally designed by Katsura Hoshino as a supporting character in the Valvrave the Liberator franchise.
