* CompleteMonster: [[spoiler:[[MadScientist Kozou Osada]] is the leader of the mansion and the head of the ongoing government-funded "GU-L" project. Basing his experiments on the real-life research on Unit 731, Osada guides stray wanderers to rent out his mansion to experiment on them and creating the UltimateLifeform that is virtually unkillable, morphing countless victims into [[BioweaponBeast monstrous and violent experiments]], and is not above using his own co-workers to further his research. Presumably coercing a maid into giving him children named Takaya and Takashi, Osada forcibly [[AbusiveParents experiments on both]] for the same reasons, even reviving Takashi from his stillborn death from his experiments. Noticing Azumi was planning to betray him to save Takashi, Osada {{Brainwashed}} her with a parasite to follow his every command, such as poisoning the young Tsutomu. With his most recent experiment being subjecting young students into a DeadlyGame to see if his experiments were deadly enough, Osada ultimately fuses with his own son's remains to create the so called "GU-L" to kill them, and even when he's defeated, he proclaims that he's unkillable and immortal.]]
