[Novelization] A Jobless Single Woman in Her Forties Struggles in Another World

I turned 35 and became nearly 40 years old. Before I knew it, I was in another world. What benefit is there in summoning a single, unemployed, loser woman in her late thirties? What? It wasn't a summoning? I just accidentally slipped into this place? I don't understand the language, and I have no cheat ability. But I'm somehow managing to survive with the help of a mysterious bag. Oh, could this bag be the cheat? I will absolutely return to Japan. With only that as my goal, I want to spend my time peacefully without causing any waves... please let me spend it that way. = Concluded in another world. I might add to it occasionally? *The story differs from the published book version partway through* [Serialization has begun!]
