my two cents on why oraboni is feeling that way:
During that trial of the Three Kings, the shadow person is actually Modern!MC before the transmigration and since she still sees that as an important part of her when she stabbed herself, it would seem as though a part of her has been gone as sacrifice to gain the Makya sword.
Or another theory, that part of herself has become the 'Makya' sword. Since the two swords could be seen as Yin and Yang, the two parts of herself could also be an allusion to this.
i could keep yapping lol
