Overview:
You play as Gustav (name can be changed) a mage who doesn't know his origins but who has been well-trained by a super-strong mage, Mavis, alongside his "half-sister" Lucy. Gustav lives a peaceful life and never questions himself about things around him until strange events start to occur, such can only be nailed with seriousness and a lot of responsibility, both of which Gustav is experiencing right now!
But it's not all about mystery... love and comedy are also at stake, as a huge variety of characters to interact with (being added little by little) and of course, the H element that we all like.
