Fine chapter... i didnt see that coming, kenpachi losing without a single scratch on the enemy? wow, that guy must be a beast...
About the 5 war potentials...
Ichigo and kenpachi are 2 confirmed war pontentials (From now on WP, or SWP special war potential)
I'd say yamamoto is another for sure. The question is which ones are the other 2?, id say isshin kurosaki, yes, ichigo's father, due to having the same zampakuto nature, and the other is yet to be seen, or aizen, even if he is locked in prison, he is still a danger to the enemy. Another possibility would be the most powerfull wizard (i dont know who is the strongest), ishida, and ishida's father... Whoever is, the kirge's killer, the who who cut him in two is one of the other 2 remaining WP, and is not yoruichi (not zampakuto = cant cut)
I wouldnt considerate the "not having zampakuto" for yourichi making her another WP, and she is only fast, not trully powerfull, and since byakuya wasnt even a war potential, how can yourichi be? they were close in speed, and byuakuya surpassed her in attack power.
Just the time will show us the WP, and how will they end the war.
PS: any chance of someone in the zero squad to be one of the war potentials?
