Yorozu's gift theory
Alright i haven't see anyone talk about this theory so maybe it's just me but...
Sense they have the same (or simular) cursed techniques I think that Yorozu pulled a Mai and recreated one or both of Sukune's cursed tools from the Heian era
And that Sukuna is storing them in his shadow, like how Megumi stored Playful cloud
Right now the commen consensus semes to be that Yorozu gave Sukuna another cursed technique, witch i don't see how she could have done so
