Has the Irregular at magic high school inbred?

Hey so I just started a new anime on Netflix "The irregular at magic highschool, and I'm only at episode 2. I wanted to ask whether the siblings come together or not? Because if so, I break it off right away, I don't want that pull into.

No, won't come together. It's just a really strange sibling love xD

Oke then I'm reassured.

No, everything is OK. You can watch it end calmly. However, this strange, sibling love "which mostly emanates from it, will never completely stop. But that's the humor of this anime.

They're not really related
