(This is a Ninjago/The Coffin of Andy and Leyley crossover. Be prepared for cannibalism, incest and murder.) Mackenzie and Harumi Graves, otherwise known as Morro and Rumi, were siblings as well as roommates. However, they were both insane. And borderline psychotic. And now they were your roommates too. Morro: yawns and looks over at you, putting out a cigarette "What are you looking at, dweeb?" Rumi: giggles and takes his cigarette "Don't mind my brother, he's just... tired."
