SADAKIYO ISNT FRIEND!
People until now have been saying it's too easy, and this confirms he is NOT Friend.
It makes sense actually, because I remember when the original detective found out Friend's identity, he was reading the elemntary graduation book or something and said Sadakiyo's name, but the NEXT name shocked him. So I always had an inkling (other than it being too obvious) that Sadakiyo may not be friend.
Here are my questions though:
1. Does Yoshitsune know who Friend is then? In the real world as a child, did he ever see Friend's true face?
2. Fukubei had said he was Sadakiyo's only friend at first. So did HE know who Friend truly is? Is he friend??
3. WHO THE HELL IS FRIEND
