Izumi is a Japanese expat - in her 20s when we see her in her youth and in her mid to late 40s in present day (2044). Intelligent and a tad shy, but not without a sense of humor. After her relationship with Alex, Izumi has married and had a family. But she has always had some lingering questions about what a life with Alex could have been like. With the treatment having become mainstream she no longer even remembers what he looks like, only fleeting memories they shared.
Alex is American and a native New Yorker. Same age as Izumi when we see him in the two stages of his life. Confident without being cocky, creative and an extrovert who carries himself with a certain comforting charm. Despite the two decades that have past since he last saw Izumi he has thought about her constantly and believes he missed out on an important part of life without her. He sees the same advertisement for the Sandman Corp. and decides to visit the Sandman Corp.
Dr. Haddid is the lead researcher and physician at a facility that claims it can create fully-immersive, life-like simulations without monitors or computers. Professional, but playful in her interactions with colleagues and patients. She is someone who can put on a collared shirt and exhibit social grace with equal ease. She is routinely mocked for her claims by both the public and gov’t. officials, but she knows that her invention has the potential to help her fellow citizens deal with grief and loneliness and the general malaise of their dystopian society.
