[Pengu]

Spoiler for episode:

Yea, Takano sure is pure insane, she doesn't need a virus.
A totally different insanety all the others have suffered through the series.
It has happened once more or less for every main character, due to the virus and other circumstances but Takono is the same no matter what world, time etc. A extremely crazy, evil and dangerous person willing to kill thousands for her deranged satisfaction.
I do hope she dies painfully slowly, but going by this series so far I am not sure of a happy ending at all.
