I looked up the novel this manga's adapted from, and the villain is...absolutely the father. He's legitimately so terrible that little sister did the world a service by killing him in the previous timeline.
Little sister is prickly, but it's understandable, and she does mature a little...but the FL is away from home a lot, so little sister rarely appears. (〜￣△￣)〜
Which is a shame, because the last thing we hear about the little sister (in the next to last chapter of the novel), big brother is hiring a tutor to teach her arithmetic in their territory. Little sister's happy ending is, she wants to learn maths. ╮(￣▽￣)╭
