I also do not think so, in my intuition of bleach..........
every one say the last sword in bleach 500 is Grimmjow's but i think Grimmjow will not use sword and attack by his Paw of Leopard king
bleach 500 is Grimmjow. any clue?
but some times the sword of grimmjow is all white .bleach 501 will tell us the truth
