Bleach vs. Naruto
Chapter 1: How it all began...
Almost a year ago ...
Ninjas from the Hidden Village of Fire were attacked by Hollows. This was their first encountering of these monsters and so they panicked. They realized that their ninjutsu attacks were ineffective against the Hollows which were actually angering the Hollows and forcing the ninjas to retreat. Never had the shinobi been able to handle such monsters and so Soul Society decided that the Hidden Village of Fire needed help. Fast.
So, Tsunade (Godaime or The Fifth Hokage)
decided to hold a meeting with Seireitei's (Court of Pure
Souls)
Commander-General, Shigekuni Yamamoto-Genryuusai.
"So,
what do you suggest should happen if a Menos Grande attacked the
village, Commander-General?" Tsunade asked.
"Then we'll have
no choice but to send some officers in." The Commander-General was
obviously concerned about the village but didn't seem to
acknowledge the fact that the Shinigami were mistreating the Konoha
ninja.
For the next couple of days Shinigami or Death Gods or Soul Reapers, were immediately directed to the Hidden Village. The Shinigami laughed and humiliated the ninjas. They thought that they were weak and useless because they couldn't purify the Hollows. So, Tsunade held another conference.
The meeting went poorly. Yamamoto and Kuchiki Byakuya ended up having to leave and Tsunade was furious. The ninjas declared war.
