Um. I dont feel like explaining it so I'll copy/paste from wikipedia. This pretty much explains it:
The main "race" of creatures inhabiting the universe of Drawn to Life are anthropomorphic anime-inspired fox like beings known as the "Raposa" ("Raposa" happens to mean "fox" in Portuguese). They were drawn by the Creator, who also drew their world and everything upon it. But the Creator abandoned the Raposa long ago.
The story begins with a Raposa named Mari crying out to the player, the Creator, to help save the village she lives in. Along the way, you meet her best friend, Jowee, and her dad, the mayor. These characters are the last remaining villagers. You design a hero for them, and then run into Wilfre, a corrupted Raposa that dabbled in creation, and spawned a legion of evil shadow-like creatures. You start by rescuing the Mayor, who set off to bring back the Raposa to the Village. As your progress, you learn that Wilfre was once a prominent member of the Village, and that in his lust for power; he stole the Book of Life, and tore the pages from it. The Mayor asks you to find and return the pages of the Book of Life, so the Creator can once again draw the missing objects from the Village. You even meet a sweet raposa named Heather who is halfway covered in shadow. She will occasionally help you. However she does not speak but merely motions and giggles.
You start by designing the Eternal Flame, which is then used to clear the darkness from each section of the village, each time you return from completing a level. Along the way, you rescue a cast of villagers, who agree to return to the Village and open up shops, restaurants and other places of interest. Mari begins training to take over as Mayor, and the Village plans a festival to celebrate. Meanwhile, adventure-hungry Jowee sneaks into a level, and you have to save him and help find an appropriate gift for Mari. This reckless act causes a rift between Jowee and Mari, but they eventually make up and grow closer as they help the hero restore the village to what it once was.
After numerous confrontations with Wilfre, he finally tricks the Mayor into appearing alone, and attacks him, stealing the Book of Life as well. Everyone tries to help the Mayor but he sadly dies in Mari's arms. Everyone devastated, but after seeing the village descend into chaos, decide to band together and stop Wilfre for good. The hero defeats Wilfre, and returns to the Village. Jowee plans to leave on a Treasure Hunt, and after saying goodbye, Mari reminisces about the past, upset about losing her dad and best friend. The story ends with Mari on the beach, shocked at seeing Jowee walk up behind her. She runs to him happily, watched over by the spirit of the Mayor, and the hero, on the cliff above. Plus after meeting with Crazy Barks, Heather finally starts speaking.
