OVA
Description
Hiroshi Ozora is the brilliant but egotistical inventor of the Mol-Unit, a device that serves as the central focus of the story. He works as a scientist for the Technology Development Department of the ZIC Corporation, a major technological firm in Tokyo in the year 2045. Despite his professional standing, Hiroshi is a somewhat scrawny and unassuming young man who harbors a deep-seated desire for fame and recognition.

Hiroshi's personality is defined by a sharp contrast between his intellectual genius and his immature, self-centered motivations. While he is capable of creating technology that defies the laws of physics, his primary drive is not the betterment of the world but the fulfillment of his own ego. He craves popularity and the admiration of the public, which leads him to use his invention for personal glory rather than purely scientific achievement. This vanity is a core aspect of his character, as he creates a superheroic alter ego named Captain Tokyo specifically to become a media sensation.

His main motivation is to become a celebrated hero. He created the Mol-Unit after a torturous all-nighter, programming its dimensional barrier to generate a costume that presents him as a tall, muscular, and invincible champion. The Mol-Unit grants its wearer abilities that operate outside normal physics, including flight, superhuman strength and speed, invulnerability, and the ability to phase through solid objects. These powers are controlled by the wearer's mind. A crucial limitation, however, is that the Mol-Unit can only remain active for 666 seconds, just over eleven minutes, before it times out and vanishes, leaving the user naked if they are not careful.

Hiroshi's role in the story is that of the instigator. His invention of the Mol-Unit sets all subsequent events in motion. After a few initial appearances as Captain Tokyo, his plans backfire when his younger sister, Mirai, curious about his work, tampers with the Mol-Unit's programming. This causes a malfunction, altering the costume's design and forcing Hiroshi to lend the device to Mirai. He then takes on a supporting role, often providing guidance and technical explanations as his sister operates as the primary hero, Moldiver.

Key relationships define his interactions. He is the older brother of Mirai Ozora, whose lighthearted tampering disrupts his plans, and Nozomu Ozora, the youngest sibling who later develops his own Mol-Unit out of spite. His mentor is Professor Amagi, an old friend and teacher who secretly becomes the villainous Dr. Machinegal. He also has a best friend, Kaoru Misaki, an astronaut whose physique Hiroshi admits to using as the model for the Captain Tokyo costume due to his own inferiority complex about his size.

Throughout the narrative, Hiroshi undergoes a degree of development. He begins as a selfish inventor driven by vanity, but is forced to cede the spotlight to his sister. This shift from primary hero to a background figure, often dealing with the consequences of his own creation, tempers his initial arrogance. His notable abilities extend beyond the superpowers granted by the Mol-Unit. As a genius inventor for a major corporation, his true talent lies in his scientific and technical expertise, which is the foundation for all the superhuman events that follow.
