Nozomu Ôzora is the youngest of the three Ozora siblings in the anime series Moldiver. He is a young boy who develops his own Mol Unit, the same experimental device that grants its user near-invincibility for a limited duration of 666 seconds. Unlike his older brother Hiroshi and sister Mirai, who use the Mol Unit to become superheroes, Nozomu creates a supervillain persona specifically to oppose them out of spite. His motivations are rooted in resentment and a desire for attention, as he dislikes both of his heroic siblings and seeks to undermine their efforts.

In the story, Nozomu serves as a secondary antagonist, adding a layer of familial conflict to the main plot involving the roboticist Dr. Machinegal. His actions are driven by petty rivalry rather than a genuine malicious agenda, which gives his character a mischievous and childlike energy. He is energetic, defiant, and enjoys causing trouble for his brother and sister, often using his own Mol-Unit suit to challenge them directly. Despite his opposition, he remains part of the Ozora family, and his role highlights the personal tensions that arise when superpowers are accessible to all members of a household.

Nozomu’s most notable ability is his proficiency with the Mol Unit, which grants him superhuman strength, speed, flight, and invulnerability for the same time limit as the other users. He can operate the suit competently, allowing him to engage in combat and aerial chases. His development across the series is minimal; he remains primarily a nuisance figure rather than undergoing a significant arc, though his presence forces the other characters to address their own relationships and priorities. Key relationships include his antagonistic dynamic with Hiroshi and Mirai, who must contend with his interference while also trying to protect him from real danger.
