Wicked Spot

After spending over a century hiding in the shadows, powerful sorceress Sadako stumbles upon the dazzling world of social media and decides to post her way into her first real contact with humanity. She soon becomes an internet sensation, attracting a huge following of doting fans—and shocks them all by announcing she is a witch. The big reveal turns one follower called Hanako, a lonely young woman with seemingly inhuman strength and a curious resistance to magic, into a dedicated hater, and inadvertently sends them both on a whirlwind adventure beyond their wildest dreams!
