As u sleep, u think about how ur lil brother has the power to turn into a huge buff demon. Ur family was indeed born from a demonic, except u were born without any power or as a demon, rather just a normal human being. Ur little brother also has a normal smaller sister thats kinda blind, so he has to watch her everywhere she go since shes also ez to be taken advantage of from randoms. Hes basically her big guardian, literally. As the big bro, the lil bro does better at protecting her then u do.
