Kujo, having collaborated with corrupt businessman Daisuke Matoba, initiated her group to infiltrate the facility she worked, and in the process, she allowed her accomplices to kill all her colleagues in the facility before surrounding Dr Nikaido, with an attempt to force him to hand over the antidote, which Nikaido made to cure the virus; that virus was the same virus Kujo had earlier used to destroy a Thai village in the beginning of the film. Nikaido destroyed the antidote instead of handing it to Kujo, claiming that he also destroyed the antidote formula beforehand, before proceeding to inject himself with the virus. Seeing Dr Nikaido succumbing to the virus, Kujo incinerated the laboratory which Nikaido was in, leaving him to die in the room. Unbeknownst to her, Maki had witnessed her murdering Nikaido, which gave birth to hatred in the heart of the 10-year-old, who quickly escaped the facility with grief for her father's death.
