Kōzō Enjōji is the father of Daisaku Enjōji, one of the three main pilots of the super robot Albegas. He runs a dental clinic from the family home, a practice he established after graduating from a well‑known medical university. Despite his sometimes intimidating appearance, he is a warm‑hearted and generous man who cares deeply for his son. Having lost his wife, he raised Daisaku alone and works hard to provide for him, though the clinic’s finances are not always steady. His personality is generally calm and tolerant, but he often argues with Daisaku over the dangers of piloting Albegas, driven by a father’s worry rather than any opposition to the fight against the Derringer. In the story, Kōzō functions as a grounding family presence for Daisaku, offering moments of domestic life and comic relief. His dental clinic also serves as a frequent setting for slice‑of‑life scenes. He maintains a friendly rivalry with another local dentist, which leads to some humorous situations. Over the course of the series, his relationship with Daisaku deepens as he gradually comes to accept his son’s role as a defender of Earth, though his protective instincts never fully fade. He has no combat abilities or direct role in the robot battles, but his support – both emotional and practical – is an important part of Daisaku’s life.
