Mahou, Hitotsu Kudasai na.

The hero of this story lives away from the clamor and noise of the big cities. He actually works in his family’s candy shop that’s nestled in a small town. A sign in the window says something about how ‘magical’ the candy is. Most would view this as a jest, but these candy makers are actually magicians. It’s just too bad that our protagonist isn’t any good with magic yet. Suddenly he’s getting help (moral support and otherwise) from all kinds of places to become the magician he was meant to be and make the best damn candy around. One of the more notable helpers is his grandmother’s familiar/cat who has become cat-girl.
