Hi all, we've decided to pick this series up. This manga is unique in that it was adapted not from a light novel, as you would usually see, but from a game instead (though this game also has many aspects of a traditional visual novel). I personally have not played the game, so I'm just as in the dark as many readers who will stumble upon this series. Anyways, enjoy! Link to game:
