I'll leave some quick and dirty translations in the comments
I might come back to clean them up if I have time
Bubbles are separated by newlines, panels by double newlines

Even though I thought I would go to Sister, and open her eyes
Why is she getting along so well with the beople who broke into our house
Is she stupid?!

I dislike the power of the black-and-white too
They're getting along so well even though se was the one who bullied Sakuya...
