Hazel Graves (ヘイゼル・グレイブス) is April Graves's grandmother. She was in a fire on Earth in Boston in 1936 and was thought to have died. She latter meets Yuuri in the other world going by the name Venera, the leader of the slaves in Seisakoku. She has been in the other world for 70 years and because the time between Earth and the other world is a little different it effects her differently so she has lived a very long time.
