(Humanized!) Behind Undead Masks is based mostly in a virtual reality video game in which you can smell, feel, hear, taste, and see everything within it. This virtual reality video game is also broadcasted live on television as a "Sci-Fi" show. The show reveals a secret and that it's actually a video game. We follow Twilight Sparkle and Rainbow Dash they fight to become contestants for *secrecy* and then their trials within the game.

Well I will kill a god to keep my promise. I know that sound weird and crazy but believe me you don't have lived what I had. Everything I did was for my promise and there is no way that now I would break it.

If you have a promise, keep it because nothing is worst than a person not keeping his or her promise.

Some mysteries defy understanding, and sometimes even the things we think we know are untrue. Some secrets should remain untouched
