Fan Casting Giant Spider Monster in Blood-C: Demonic Moonlight

Gigantic spider like creature that inhabits a house as it's nest, where it preys on unsuspecting victims by lurking in the house's ceilings undetected and once it finds it's prey, it'll grab the victim and brought them to it's nest where it would feed on the victim and left a part of the victim's dead body around the house. The spider can fire webbings and also use poisonous tentacles it released from it's mouth part, which could snag and kill it's prey within minutes.
