Hayate “DoA”

The 18th leader of the Mugen Tenshin clan, Kasumi and Ayane's older brother, and a good friend and rival of Ryu Hayabusa. After suffering a defeat from Raidou, he was made into an experiment subject in a DOATEC laboratory, and had temporarily lost his memories. After being discovered by Hitomi, he became known as Ein and joined the 2nd DOA Tournament, where he was able to rediscover his own self. Hayate swore to repay DOATEC for everything that was done to him and his family. He is concerned about Kasumi and Ayane, and currently follows in the tracks of a tattooed man, who he thinks will bring him closer to finding Donovan.
