How does the seal placed on Naruto actually work/or used to work anyway?
interesting question that brings out a certain idea:
-if the fourth use the death god seal pull out kyuubi's soul.. then shouldn't both the fourth and the kyuubi are now inside deathgod's belly fighting eternally???
-from long ago we know that inside naruto is only half of the kyuubi (either the ying or the yang.. i forgot)
-now we found out that somehow kushina pop out inside naruto...
what if: the fourth use the deathgod seal, but instead of pulling out all kyuubi soul and let deathgod eat both his and kyuubi soul, he split kyuubi soul into two. half goes with him inside deathgod's belly for an eternal fight, while the other half goes with mommy naruto inside naruto's belly.
