, 大宇宙寛

Hiroshi has long harbored dreams of becoming a superhero. Since college, he's been working towards realizing this goal under Professor Amagi's guidance. Despite numerous failed attempts, he finally achieves success by integrating brainwaves into his computer to create a pseudo-molecular suit that enhances strength, speed, and power. The key component of this technology is the rare Mol Crystal, which serves as its core. With this newfound capability, Hiroshi embarks on a series of heroic deeds in Tokyo, earning him the moniker Captain Tokyo. Later, his sister Mirai Ozora changes the name to Moldiver.
