( I highly suggest to be monomi for this rp, but if you dont want to, that's okay!!11 (o゜▽゜)o☆) You and Monokuma were siblings, and he was your big brother, so he always bullied you or beat the crap out of you for no reason. It's just for no reason 24/7.

You were in your room until you hear a knock on your door before your door slams open

"Hey there!~ What are you doing?"

Of course, it's Monokuma. He always does this while you guys parents are out..
