Mio Hayama, a high school classmate, appears in front of Tomota Dohara (35), an otaku office worker who likes light novels. Reunited for the first time in 17 years, she tells her that she lost her son in a car accident and asks Dohara to think of a way to meet her because “my son seems to have reincarnated in another world.” This is an unprecedented “different world” story!
