More Fillers after Bijuu Showdown
Believe it or not, there's a possibilities that they are going to add more fillers due to the latest episode when they decided to add a bit filler scene of Kakashi Squad struggling against Mangetsu which never shown in the manga before Kakashi & Gai gets to the next battlefield when Tobi about to get his Hands on the Nine tails.
What really bothers me the most is it was Said Mangetsu is Known to be the Strongest of the Seven Swordsmen of the Mist yet it was misfortune to see him any screen time. We have yet to see him any actions sequences that portrayed this character except when Suigetsu explained every 7 swordsmens along the way.
They added fillers of every 7 swordsmen even Kekkia Genkia users yet we havn't seen Mangetsu Filler fights.
You guys probably think how are they going to add fillers when everyone gathered up and on their way to aid Naruto
I can see variety ways how they're going to add fillers after Bijuu Showdown.
(A) War Extension Plot
(B) Flash Back Fillers
(C) Random Fillers
(D) Filler Arc/ Movie Special
Out of all the Fillers, I think Option (A) is more probable than the others and I hope it is the case cause they made the war arc better, plus the way things are, if Kabuto were defeated, what other options will they make for good fillers extension fights.
Also Right After Bijuu showdown, they may add canon for Sasuke new Ems but then its going to integrate with the fillers war. After everyone gathers up, we see Sasuke walking up into the thunderclouds and about to face Kabuto.
As you guys probably should know by now, Studio Pierrot will always find the way to fill in the gap between canon story or integrated into the canon materials. Anime is differ to the manga, this Anime won't follow everything accordingly to the manga , it's like Sequel Version of the Naruto Manga.
Take a look at the 6 tails, they got some filler moment when Naruto met him from the 6 tails arc, or the sword flash back, yes I'm refering to Samehada, you just can't simpily deny it.
