It will likely be new information, but we can guess! If that dagger does unlock memories, if that manages to pierce the first (a big if since he's avoiding and fending off Saito's super powered strikes with little effort) and Shinoa gets her consciousness back, she could expel the first of her own accord, maybe.

More safer ways, hoping Yu has something, maybe Kureto and the resources he has at his disposal could reseal a demon of Shikama Doji's magnitude.
