Mikoto Gray

Mikoto Gray is a higher-up in NeoVigilance Corp and can be repeatedly seen conversing with Veronica Goldenrod.

In NeoVigilance Corp
It is known that Mikoto is a member of NeoVigilance Corp. In her first letter to Veronica, Mikoto refers to herself as the "Producer" of Castaway, so it's assumed that she has a more important role than Veronica.

Dear Veronica.

The first attempt at Surveillance and Viewership Experiment #006, alternatively named "The Castaway Project"   was wildly successful. Due to it's popularity among the public,   Darius   and I have to decided to let you continue the project, renewing it for a second season if you will. The novelty of the "contestants" not knowing they're being filmed hasn't quite worn off just yet. No one will fall for a free luxury cruise after the countless news reports, so I'd suggest coming up with a fresh scheme.

Yours Sincerely,

Your "Producer",

Mikoto.

Family
Mikoto is the adoptive daughter of Darius Gray. She doesn't know who her birth parents are or where they are currently located.

It is assumed that her birth family are in Japan, her home country.

Season 2, Pre Season

Season 4
Letter to Veronica from Mikoto:

Dear Veronica,

Castaway has become a global phenomenon. Darius   and I didn't have much faith in you, if any at all, when you started this project. I now know that we were wrong, and I'd like to apologize on behalf of both of us. Your experiment maybe the future of our company. And the best part is, everyone wants to a part of it. We don't have to resort to tactics anymore. So get out there and renew it for a fourth season.

Your's sincerely,

Mikoto.

Trivia

 * In Chinese, Mikoto can be written as 尊 meaning "nobility".
 * This draws parallels to how Darius adopted Mikoto and gave her a large role in his company when she came of age, similarly to how nobles inherit their position from their parents.
