Kenji Oosawa (Father), Hitomi Oosawa (Twin Sister)
Usually seen smiling, Maria is one of the main characters of the series. Two years ago during the events of 428: Fūsa Sareta Shibuya de, she was mistakenly abducted by Snake terrorists who mistook her for her twin sister, Hitomi Ōsawa, their true target, as Hitomi's blood was resistant to the Ua virus. Snake later infected Maria with the Ua virus to force her father, Kenji Ōsawa, to make them a cure to the Ua virus to save her life. While her life was saved thanks to her father's anti-virus, the trauma she endured during the Shibuya incident made her suffer amnesia. As a result, she can't remember certain events during that incident; including not having met Alphard Alshua before. Prior to the Shibuya incident, she befriended Canaan after being saved from hoodlums during a trip somewhere in the Middle East. As her dream is to become a photographer, she became the partner of Minoru Minorikawa before the pair's assignment in Shanghai and her subsequent reuniting with Canaan.
Maria has long blond hair and golden eyes. In the begining of the anime, she is seen wearing an outfit the consist of a white shirt with a black tanktop underneath, a brown choker, black shorts, a brown necklace, and black and brown combat boots. She usually carries a camera and sometimes has a backpack with her.
