Hiromi Goto’s 2021 Shadow Life is a stand-alone modern fantasy graphic novella. Illustrations are by Ann Xu.
Consigned to a retirement home by her well-meaning children, Komiko waits for a suitable moment, then slips away into the night, taking with her only a few reminders of her previous life. Komiko carefully conceals her new home — a bachelor apartment — from her alarmed children. They do not see her as a functioning adult and would only try to place her in another facility.
As it happens, none of her children are the entity about whom she should be the most worried.
