I LOVE the FULL song and the PV!!
It doesn't have a plot(and if you try to give it one it doesn't work so I'ma go with it not having one) and it's great. The struggles through life and all that.
Different locations(air base, forest/river and dryish place(kinda iraq-esuqe with the buildings)) and some great closeups. I kinda guessed there wouldn't be many erena shots so I'm not disappointed(as I had no expectations lol)
I have to say I love Acchan's hair here
I also really like Yuko's <3
