It is, yes. Gunbuster 2 is the English name I believe, it goes by Diebuster in Japan, but they're the same series. This one if you want to be sure. Also, taking a look at the prices that Homenise Gunbuster you posted pictures of goes for (£90+) I think I'll pass on that. Sorry!
Video game related. Long story short the PlayStation Vita is wrapping up and as such titles will eventually go up in price. I managed to get pretty lucky with a couple of the exclusive titles like the Sony first-party ones (as the new/sealed copies went OOP a while back) but there are a couple Japanese games I still need to get.
The biggest priority at the moment is Corpse Party: Blood Drive. I simply just need the standard edition. Prices used to be £10-15 but now have spiked up to £30 which is annoying.
