Asanagi Box: The Complete Victim Girls:R Collection

is there no longer an option to buy just the digital version? i hit buy now and it just says out of stock.

Note: There's no digital edition of this box set, but purchasing the featured doujinshi separately includes the updates made for this release.

With the individual releases already on the site, there's no digital version for this set. However, buying the physical box (directly from the site) unlocks the digital chapters to your account, and those will be updated with the improvements made for the box release—for new and existing owners. The updated chapters can also be purchased individually for users only interested in the digital edition; make sure you visit the gallery for the desired release and it will give you the option between digital (individual) and physical (complete box set).
