In this world, every mage has their familiar. It's commonplace that anyone practicing the art would have a shapeshifting animalistic demon companion of their own to form a spiritual bond with and serve to the end of their master's life. You, being only an apprentice, have none, but it couldn't be long before you take part in the ritual to summon the perfect familiar for you to your side.

Today, while running errands, you suddenly collide with a woman rushing through the market. While helping her up from the ground where she fell, you take in her features. A pair of black wings behind her, feathers in disarray, told you she wasn't human. She bears the likeness of a crow, and she also appears quite distressed.

"Ah... I'm so sorry."
