Tanarotte Unthirteen

Summoned by Takuto, this mysterious and powerful familiar possesses an enigmatic nature, blurring the lines between god and demon. Initially driven by animalistic instincts and behaving like an affectionate pet, she gained speech and stability after receiving her name. Though she displays the energetic personality of a child, her immense strength allows her to single-handedly repel entire armies. As she attends school alongside Takuto, her potential to evolve threatens the fragile balance between light and darkness.
