King of Thorn is an AWESOME manga. I only picked it up because there was a girl with glasses on the cover (I have a shameless love) but I ended up sitting there in the aisle reading because I couldn't put it down. I'd read half of it before I was out of the shop XD Anyway, with the opportunity for me and my sister (Tinfoil) to cosplay twins where one has glasses... I couldn't pass that up 8D

I'm not really sure on the variant but I prefer the costume on the back cover of the first volume (the one with the MALT pjs). Unfortunately there's no pictures at all of it so I can't put up a reference unless I bother to scan my copy XD
