Blood related, the pink haired one is your sister. She's teasy and does good banter with the MC.

Blood related, is the second game of a series (the first one has a different, non-sister heroine, not a direct sequel though.. multiverse shenanigans, but you still have to read it) I'm only posting this because she's widely agreed by a lot of people here to be the best imouto heroine of all time, and is voiced by the one and only Sawasawa Sawa who voices Frieren and Anya

Mainly comedy focused game but there's a love triangle between your non blood related sister and your blood related sister so it's interesting.

Blood related, she's a little sickly so you "take care of her", country kino. Straightforward single heroine game. Fairly new game by a well known studio.
