Her contract job has ended. Unemployed, single, no boyfriend— 35-year-old Rie Sato has nothing going for her. Then one day, she wakes up to find herself… in another world!? All she has to rely on are a mysterious bag and the survival knowledge she’s built up over the years. In a completely unknown world where neither the language nor the culture makes sense, Rie struggles to survive. Her goal is simple: “I’m absolutely going back to Japan!” To stay alive, she interacts with villagers and faces all kinds of otherworldly troubles head-on. Romance? She doesn’t have time for that! If it means getting home, she won’t lose to any hardship! “Don’t underestimate a woman pushing forty!” Thus begins Rie’s second life in a strange new world!
