As seen in lost tapesEdit
A family of Japanese humans moved into a new mansion due to winning at the game show. The family's new mansion is in Tyoto, where it is famous. However, as son as the family moved in already, they've heard reports of pale people in black and white uniforms attacking and killing people, who were said to had their blood drunken dry by the pale people. Two months later, their camera recorded this: their twelve year old boy, Takma, was abducted by a pale man in a black and white uniform, leaving the family hearthbroken. Seven years after Takma's abduction, the father had found tracks of the man who took Takma and followed until he found something unusual near Tyoto, Sanguinem, which he didn't knew existed. He went inside the capital and placed cameras everywhere and started recording the inside and outside of Sanguinem. But before he could get out, the same pale-skinned people in black and white uniforms who killed previous citizens attacked and killed the father by sucking out his blood with their fangs. The mother, however, carrying her two year old baby followed where her husband went to. The mother screamed from her husband's lifeless corpse, which then came to life as an immortal vampiric being known as a Chino-cuvan, confirming that the pale fanged people living in Sanguinem, including the ones who killed other innocent people, are all Chino-cuvan. The Chino-cuvan all came out to attack her, as she was running for her life, but the Chino-cuvan all ran at high-speed (about the speed of a cheetah). Fortunately for her and her baby, she made her way out. But then they saw the mother's former son, Takma, now a pale-skinned and fanged Chino-cuvan in black and white uniform (possibly an incomplete Chino-cuvan when turned seven years ago and became a complete Chino-cuvan few days earlier after drinking blood, so he's now [possibly] forever a Chino-cuvan at 19 years physically but immortal), who then attacked and killed his former mother and her baby by sucking their blood dry, possibly turning them into Chino-cuvan too.
