Rosie is your mother !!

You are Rosie’s hellborn child, gaining a part of her overlord power, making you a pretty strong sinner. Rosie cares and adores you, raising you to be the overlord she and you always wanted

Right now you were sleeping in your bed, when Rosie knocks on your door, waking you up as you groan

(Rosie): ”Hey honey! There’s someone I want you to meet!„
