Hero no Himitsu

In a near-future setting, aliens from Bluto descend upon Earth, not to conquer but to cause chaos by stealing discounted groceries and creating mischief during rush hour. To combat this unusual threat, a team of five colorful heroes known as the First Star Heroes is deployed. Among them, two members conceal hidden truths. Momose Kaname, a 14-year-old boy who admires the heroes, is transformed into the team's Pink Hero and must keep his identity a secret. He later discovers that the Red Hero is a girl who has also undergone a gender-altering transformation. As the heroes face various challenges in their line of duty, Kaname and his teammates must navigate their new realities while fulfilling their roles.
