Yumekui Merry is about a dream-demon called Merry Nightmare, who lost her memory after being forced into the real world by hercules, probably the strongest dream demon in existance, as a cause of her fighting back while he was taking other dream demons to the real world. The only thing she seems to remember is wanting to go back to the dream world. It´s also about a boy( Yumeji Fujiwara) who has been able to see what people are going to dream about by encircling his eyes with his thumb and index-finger. When Merry falls atop Yumeji and he promises to send her back to the dream world, strange things start to happen. It´s not one of the best anime´s i have seen, but it contains one of my favourite favourite villains of all times and my namesake: Misteltainn( has been noted to be spelled differently by most people and can therefore cause a bit of a confusion) but i think its worthy of being watched, even if though misteltainn is the only reason you actually watch it for.
