Her immense power, accumulated through centuries of casual slime-slaying, inevitably draws attention, pulling her into a world of unexpected encounters and magical mishaps. Azusa soon finds her once-solitary life populated by dragons, demons, and other powerful beings, all eager to challenge or befriend the legendary Witch of the Highlands.
