What is the line between good and evil... What is justice?
"Heart Ether" is a magical power born from human love and hope. To protect the world from Negatia, monsters that steal this power, the fairy Manicure was searching for Magical Girls. Unexpectedly, the narcissist Taro is chosen. Joined by the ice-wielding Magical Girl Shirayuki, the three begin their battle against Negatia. However, Negatia were born from the "specific emotions" that Manicure once banished from the world. It's not about "defeating the enemy," but "how to face the darkness in one's heart." A painful and bittersweet Magical Girl story woven by Taro, Shirayuki, and Manicure.
