So after reading the manga for 15 chapters and watching the anime for 4 episodes. What I understand is that they wanted to hide the fact that she killed her family when she was 3/4 years old so they hypnotized her into hating blood, then because of her hating blood she was considered "weak" and then helped some random girl getting bullied by girls which subsequently caused those girls to start harassing and bully her, which then caused her to have trauma, So she ended up becoming a shut-in for 3 years where she was completely contempt with it (I dont know the whole story. I literally know up until where I dropped it because of how frustrating it was. I have not read the light novels either. So, my knowledge and statements could be completely ignorant and stupid) Then after becoming a shut-in. Her father wanted her to become one of the 7 generals for god knows what. I think I saw something about him wanting her to just go outside. But I highly doubt it was just that. (Most likely for her to become empress with her power) So, now I'm annoyed because well. They caused it all to happen no? (Hypnotized her to not go on a rampage, ends up getting bullied, goes on another rampage, gets traumatized from all the bullying, becomes a shut-in for 3 years, gets forcefully selected as one of the 7 generals.) Like its just so frustrating. And they still continue to lie to her about it and let her continue being an anxious wreck surrounded by her trauma. Shes scared of dying because she thinks shes weak. Just leaves a sour taste in my mouth I guess.
EDIT: I dont mind spoilers in the replies to this if you do. I'll probably just keep this dropped, not for me as you can see. I dont know anything about the harem stuff, but I do like Vill being the main "romance" for the female lead, But I dont really know any of the other characters.
