Irene Lew

Ryu's girlfriend. She helps Ryu with running his shop. In the Ninja Gaiden games she was a CIA agent, however, judging by her behavior in the OAV it seems that the authors changed her character. Irene is a gentle and emotional girl. In case of danger, she knows how to pull the trigger but generally she is not a fighting kind of character. Irene is deeply in love with Ryu.
