People are going to die!
First I put this with the spoilers prefix because I am going to mention some information from chapter 544!
First off, people are curious as to why the Jinchurikai have a sharingan and rinnegan. As the other people have stated, it is Madara's "Paths of Pain". I didn't realize it at first either so I don't have much room to talk.
Anyways I've seen alot of people comment that they dont want this person or that person to die. I know Im going to catch a lot of crap for this thread but whatever.
Anyways, people this is a story and it is borderline epic. And no I don't mean epic as in the slang term for it nowadays, but the old school meaning of a story with twists and turns and it is long and great. Example: The Illiad and The Oddesey.
In epics, people die. Big important characters. I saw in another thread that Bee is about to die. And I completely agree! But I saw some people that were like " Your stupid they're not going to die." People in a good story, particularly in the action genre, the author gets you attached to characters just to take them away from you. It causes emotion, and makes the reader want to know what happens next.
This is war. The joint ninja alliance is going up against most of the legendary ninjas of past and the new paths of madara! People are going to die. Just saying.
Now commence bashing.
