Mighty♡Heart

An evil group wearing robotic suits plans to take over Earth and refers to each other as "Phantom." One of them, Tenkawa Toichi, lives as a regular student in a high school. A new student, Maishima Kokoro, arrives. She is attractive, assertive, and uninterested in romance or sexual relationships. Her hidden role is as the last human defense against the evil group. When danger arises, she transforms into "Mighty Heart," the Angel of Judgment. However, this form is easily defeated. Her true strength emerges during moments of extreme shyness, especially when she is teased or embarrassed and begins to cry. At those times, she releases a powerful beam capable of 1 ton of TNT. This ability is used in nearly every battle. The manga includes two one-shot stories titled "Onekomimi" and "Onekomimi 2."
