Agree with everyone.
PV answers nothing and probably raises more questions, wtf? I'm sad there are no snipers taking pot shots from the top of the hill

. Looked like they just randomly died. The digital stuff on their hands and what looked like some holographic dome thing was kind of cool.
I am convinced there will be another ridiculously long drama version to be released or coupled with the single DVD, otherwise this is a huge disappointment. Maybe there's some cool war type stuff they're saving for the long PV, lol. At this point though, it seems like their PVs are just another medium for famous directors to show off with random stuff.
Also disappointed they ruined the Kachuusha outfits. Come on, man, those outfits are cute as hell.
As far as the song goes, it's better than I initially thought, but still meh. It'll probably grow on me by the time it actually comes out.
And I am totally 100% fine with Mayuyu center. I personally welcome our new cyborg overlord.
