I think I am coincidentally copying your Aniplex buys. I'll most likely stick to the MVM sets for Kizumonogatari and Season 2 however as Kizu is pretty much the same release and S2 boxset is an uncomfortable purchase for a tiny upgrade.Nyahaha. It's a great collection, and a rather rocky ride considering what I should have done was buy the Second Season volumes when I was in my second year (2014-2015 where the rate was at its very best) because the referendum happened not long after that in 2016 where it got more expensive. It was fortunate that Owari 3 and Zoku Owari was about £122 overall from UP1 USA thanks to the rate being £1 = $1.36/1.37 at the moment.
As for what I plan to do next with Aniplex, if you know me already (or saw my Otaku Collection page on my blog) the next franchise left to sort out is none other than the Fate franchise.
Are the Funi ones Region Free by any chance?
