#well choso and yuuji are blood related siblings in some very twisted way so whatever

[olasketches]

ok so the twin theory regarding yuuji and sukuna doesn't make sense to me in a literal sense but there are some aspects of it that... just make too much sense. the theory might turn out to be true in a way. they can still be twins or like twins... just not blood related ones. well maybe yuuji is a part of sukuna's bloodline considering how similar wasuke looks like to og sukuna or why yuuji has pink hair so in that case they would be blood related.. just not blood related twins. I think it might have more to do with their souls and how they've come to coexist together when they were sharing the same body.

yuuji and sukuna being twins no because they're blood related siblings but because of their souls would be such a interesting twist considering the connection between the soul and the body in jjk world. maybe kejaku feed gave yuuji a part of sukuna's soul or created him using a part of sukuna's soul. mahito stated that 'the soul should always exist before the body' and 'the shape of the body will always be depended on the shape of the soul' by that logic it would mean that the body is like a container in which the soul resides and once the body dies the soul can no longer live in it. Im not gonna dive into that rabbit hole and speculate the physics behind it but the baseline is that there is a deep connection between body and soul. they're intertwined in some very unique way and we already know that there must be a connection between yuuji and sukuna's souls as they were able to coexist in one body. you could even say that in a way they were like conjoined twins, sharing and inhabiting the same flesh... ALSO there’s this very subtle imagery of yuuji and sukuna's souls being conjoined together so y'know...

I think what I'm trying to say is that yuuji and sukuna might not be (blood-related) twins but maybe their souls are.
