Mighty♡Heart  

An evil organization with members wearing robotic-looking suits plans to take over the Earth. They refer to each other as "Mysterious persons," or "Phantoms." One of their members, Tenkawa Toichi, disguises himself as an ordinary high school student. Meanwhile, Maishima Kokoro, a new transfer student with an intense gaze and no interest in romantic relationships or sexual experiences, arrives at the school. Her true identity is that of the last hope against the evil army: when danger arises, she transforms into "Mighty Heart," the Angel of Judgment. Despite her weak appearance, her real power lies in her ability to release a devastating beam of energy equivalent to 1 ton of TNT when she experiences extreme embarrassment, especially when sexually teased. This powerful weapon is often used as the final weapon in battles against the evil organization.
