I'm actually going to have to agree with [@Archmage MC] on this one. As long as it doesn't get too publically addressed, and doesn't mess with the other characters, I don't see a problem. In fact, I think it would take away from Light if she wasn't able break the fourth wall. One could argue that Light's superpower is her metaness. After all, most of her special abilities stem from not altering her self, but altering the laws of the universe, which are strictly defined. But if someone walked in and was more meta than her, well, it'd kind of suck for the character. Like if the fastest man alive, discovered that there was an even faster man alive, and this man also had an assortment of other powers, like flying, laser eyes, and icebreath. For example. Strictly hypothetical, of course. So I'm going to vote that if anyone in the RP can break the fourth wall, Light can. Y'know, for whatever my vote is worth.
