Our take on Zero-Sum Heart

Rather than treating romance as a route toward a conventional happy ending, the story makes the protagonist’s ability to love part of the supernatural bargain. The visual novel replaces ordinary relationship progression with a question about whether affection has meaning when magic controls the conditions.

What is Zero-Sum Heart?

Zero-Sum Heart is a short visual novel set at a magical boarding school on the protagonist’s eighteenth birthday.

After trading her heart to a witch for universal admiration, she gains dangerous power, a one-sided romance, and an adoring but faceless crowd. Choices shape the story as it explores whether love is possible without a heart. The game combines romance, teen drama, thriller and horror, and magical realism across a roughly 2-hour narrative with multiple endings. Hand-drawn psychedelic illustrations blur reality and fantasy, while an original soundtrack adds a sinister, witch-themed atmosphere. Content includes self-mutilation, violence, gore, stalking, harassment, abuse, toxic relationships, murder, suicide, and potentially dubious consent involving magical influence.
