Hahaha, your pinkie is totally mine! 😆 Seriously though Zero-One became a bit repetitive and predictable for me early on, but it really picked up around episode 20. After that, it became such an exciting journey, with the supporting cast, Aruto’s forms, and those intense fight scenes. Some of the choreography was just mind-blowing!

Flow's music has been a part of my life for over 15 years, back when I first recall getting into anime(well anime outside of the shonen genre), so when you mentioned they did Gotchard's opening, I was geeking out right now. Flow’s Naruto opening is legendary, and Back-On always brings that energy, I think it would make Gotchard's opening a perfect mix of nostalgia and excitement.

Update: The first song I recall hearing from Flow was the opening to an awesome anime called "Eureka Seven". It's one of my favorites.

Every time I hear this song, I get a sudden rush of nostalgia to those childhood days of 2005:

I remember "Days".  Besides Eureka Seven, my first introduction to Flow was through the anime Code Geass.

But my introduction for Back-On was through the song "Chain". I never saw the anime Air Gear, but this song is kind of awesome. Over time, I've heard some of their other stuff, but I wonder if they still make songs in this style.

Oh! I have seen Code Geass before and I remember “Colors”. Flow has a distinct style. 
 

I think that was the song I remember Back-On for. I never saw Air Gear either, but I remember getting recommended that song.
