There's one thing that confuses me about the story.

These experiments, did the brother actually "rape" his sister or "manipulated" her in any way which cause her to be a yandere?

Or could it be that the sister read her brother's blog, and took it in a way which the brother didn't want it?

I know that in the sequel, the brother did indeed wanted his sister to be in love with him, but not in this form of matter.

It's true, I am confused as well. There's probably some imagination that goes between this and the sequel.
