Naruto Solo'ing 6 Bijuus? Please send over that manga page for I must have missed it given the colossal aid the Bijuus lent him and their power. Those Bijuus shouldn't be a problem for Sasuke in EMS given how he has a large Enton blade and Amaterasu. If eight tails could succumb to it who posses greater tails for defense, these Bijuus shouldn't pose any threat.
@OP Madara is in the dark for the most part as he doesn't know the Clan is wiped out. He could have reacted strongly to Sasuke for interfering but seeing that he was an Uchiha, he actually smiled that lacked hardness. So far, he has to reason to respond to Sasuke in such a manner.
Sasuke fans at their finest
That Girl at her worst.
