I was taking a walk earlier and something crossed my mind. Does the Calamity distinguish between people who are related by adoption rather than blood? Say my adopted sibling was in Class 3-3 in Yomiyama. Would I be in danger of the curse because of said adoption, or would I be safe from the Calamity because I have no actual blood relation to my sibling?

All deaths of siblings shown in this series are of blood relations so I'm wondering if it's possible that the curse wouldn't effect you if you aren't related by blood?
