Okay, let me explain this before you go "WTF?! TWO YAMI MARIKS?!"
we have Vel who plays the BEST YM ever and then we have myself who plays an alternate universe Marik/YM. This is my own twisted thoughts but it does have the possibility of happening there.
Also, I'm not putting this under mature because there's no blood and no one is naked. If you think it should be under mature because of the knives then you really need to stop being so sheltered.
