サマール・ハッピネス

She's usually known as the "Bloody Angel", but her real name is Samar Happiness. She's an individual from the Kingdom of Zeth that is usually deemed as a monster for her cruelty and insane obsession over killing. She has an incomparable and insatiable lust for murder, one that rivals or probably even surpasses that of a Demon King. In appearance, she looks like a cute and naive young girl, but this is nothing but a mask hiding a hideous monster. In the year GI1011, eight years ago, she disguised herself as a nurse and ventured into the Hospital Nata de Coco, where it is said that she brutally slaughtered a total of 255 people in a single night. She was captured and sentenced to be imprisoned for 142 years. [From AliceSoft Wiki]
