Humans Don't Make Good Familiars

Suma, a bird-like mage from another world, accidentally summons one of the most powerful familiars her world has ever seen… a normal British teenager. Born with a natural affinity for Chaos Magic that manifests itself once entering her world, Jake becomes a caring friend to the young mage, and a formidable enemy to anyone who may dare to hurt her. But Suma’s world is plagued by war, and Suma has been drafted.
