just one more look at your open wound bro pleaseee i promise i wont be weird this time

on the one hand I get why it makes sense, in brother!AUs, to position sukuna as the stronger brother over yuuji. on the other hand, i think we could have a lot more fun extending the canon aspect of yuuji being the one person who could suppress him. ie. big bro sukuna who's stronger than everyone around him and yet somehow he gets his ass beat by his little brother every time. and it drives him fucking insane

yuuji discovering his bloodlust because of sukuna

I love that he has absolutely no qualms when it comes to hurting sukuna. yuuji maimed him. clawed his heart. pulled sukuna's hair only to bash his face against his knee. spat on his face w blood. manhandled him and hit him w like 10+ consecutive black flashes in a row. he did all that w only pure cold-blooded intent and no hesitation. not because he had to.

gotta be honest I think a REAL juicy dynamic is when someone has a True Love and a Soulmate and they are two different people

see this person is the love of my life I would follow them anywhere every day is brighter for having them in it. and THIS bastard shares a soul with me we'll find each other in every universe and understand each other in ways no other living being could. neither of us are particularly thrilled about this
