OMG!!!! It's Yamamoto vs. Amagai (with super bakkutou and bankai)it's the battle of the fire zanpaktous, and it seems they do have a history behind them.Seems that Yamamoto had a duel with Amagai's father and killed him and Amagai swore to one day take revenge on Yamamoto.
Now Ichigo will fight Amagai fo involving Lurychiyo in all of this.
Damn!! now I can't wait for next week.
