I swear to god.. if there is a new opening when these fillers end, I'm going to go out and beat whoever's-in-charge-of-this into oblivion with a croquet mallet. they did the flashback arc during my last favorite opening: Diver. Which coincidentally is another NICO touches the walls song.
YESSSSSS SEE THIS IS WHAT IM TALKING ABOUT!!!!! Great filler,if they would make all the fillers relevant and meaningful like this one was, every LITTLE THING IS GOING TO BE ALRIGHT...AS IN BOB MARLEY!!!!!! THE NEXT FILLER SHOULD BE PRETTY COOL TOO. ANYWAY I ALWAYS THOUGHT SHINO WAS AN IMPORTANT GUY,JUST NOT ALWAYS HIGHLIGHTED.
Sorry to burst your bubble but Foo was used as the human sacrifice to resurrect Torune. That's why Foo didn't pop up as a Edo Tensei Summoning. As cool as that sounds, there will not be a Ino vs Foo filler.
