Mighty Heart

A malevolent group, whose members wear peculiar robotic suits, is plotting to take over the world. They refer to each other as Mysterious person Phantom. One of their members, Tenkawa Toichi, lives a double life as a regular high school student. One day, Maishima Kokoro, a striking but fierce new transfer student, arrives and shows no interest in romantic or sexual relationships. Little does anyone know, she is actually the last hope for humanity against the evil army. When danger arises, she transforms into Mighty Heart, the Angel of Judgment…but unfortunately, she is easily defeated every time. However, her true strength lies in her extreme shyness, which triggers her powerful beam weapon when she reaches the peak of embarrassment. This devastating attack is equivalent to 1 ton of TNT and is often unleashed when she is sexually provoked. She is often used as a final weapon in battles.
