Questions & Answers about imouto wa buranko ni nottaato, sunaba de tomodachi to asobimashita.
は marks 妹 as the topic of the sentence.
So 妹は means something like:
- As for my younger sister...
- My younger sister...
It does not exactly mean the same thing as an English subject marker. It tells the listener what the sentence is about. In this sentence, everything that follows describes what the younger sister did.
Japanese often leaves out words like my, your, or the when they are understood from context.
So 妹 literally just means younger sister, but in a normal sentence it often naturally refers to my younger sister unless the context says otherwise.
This is very common in Japanese:
- 母 can mean my mother
- 友達 can mean a friend or friends
- Japanese relies heavily on context instead of explicit possessives and articles
