NA Localization:
A certain very talented, very attractive secretary (of light) wears this headband. She follows a policy of "freewheeling savagery," serving as CEO of one of the world's premier private military contractors.
Incidentally, her superspy outfit and corporate persona may come across as quite foxy, but in truth, she is a bunny.
Fan Translation:
The ear decoration worn by a certain omnipotent and beautiful secretary (Light), who is also the CEO of a world-leading private military company with a "free and uncontrolled wildness" policy.
By the way, while she is quite a fox in her SPY appearance and company name, ultimately, she is a bunny.
