Arcana+
Got my Arcana+ recently so I thought I'd share some more details on it...
There's two of them to date, the themes are Boys in Uniform (left) and Male Seniors (right).
Interestingly, neither of them have volume numbers and they only advertise each other at the end (ie. no plans for more Arcana+ atm?). There are no bonus illustrations like the ones seen in the Arcana series.
