Description
Hiromi Amachi is the daughter of Professor Souzou Amachi, the brilliant scientist who developed the Tekkaman system, and she serves as a key member of the Earth defense team known as the Space Knights. As the main female lead of the original 1975 series, she is a constant presence alongside the protagonist Joji Minami, acting as his partner and the pilot of the support ship from which the robot Pegas launches.

Hiromi has a gentle and caring personality, often described as very kind and overprotective, which serves as a counterbalance to the brash and hot-headed nature of Joji. While she is not presented as a particularly strong frontline fighter, she is technically skilled and competent in her role as a test pilot and support operator, proving herself capable in high-pressure situations in space. Her character often fits the archetype of the damsel in distress, frequently requiring rescue, but her unwavering loyalty and compassion make her the emotional anchor for the team.

Her primary motivation stems from her commitment to her father's work and the survival of humanity. Alongside Joji and their alien allies Andro Umeda and Mutan, Hiromi fights against the invading Waldastar, an alien race determined to conquer a dying Earth. She is deeply invested in the success of their mission, which includes not only repelling the invaders but also continuing research on the Leap Flight Engine to find a new home for humanity.

Hiromi shares an inseparable bond with Joji Minami, the young pilot who transforms into the armored hero Tekkaman. She considers herself his girlfriend, and their connection remains strong throughout the series, even if their relationship never becomes formally defined. She works closely with her father, the Professor, whose technological genius provides the means for their fight, and alongside the mysterious alien Andro and the small, squirrel-like Mutan, she helps form the core of the Space Knights.

Throughout the series, Hiromi does not undergo a dramatic personality shift, but her character is defined by her growing resilience and steadfastness in the face of overwhelming odds. As the story progresses towards its conclusion, humanity finally finds a new planet and prepares to leave a ravaged Earth. In the final battle, after the Waldastar launch a devastating attack, Joji makes the decision to confront the enemy alone, sending his friends, including Hiromi, ahead to secure humanity's future on the new world. Her primary ability lies in her technical expertise as a test pilot and her operation of the support systems crucial for Tekkaman to deploy into battle, providing the logistical backbone for the Space Knight's missions.
