Clio Hera Vasilieva, a nineteen year old young lady.
An IT Major student at Gibson University by day.
And a part time barrista at a coffee shop near her apartment.
Who would've thought that this nice and pretty girl would be such a criminal when the lights are finally out?
As if there is a switch inside her that would automatically turn on when it is finally dark.
Clio's killings are somewhat modern.
She'll film every murder she would execute then will hack her victim's SNS account and would post videos of their horrifying death.
She's a verdugo. The modern verdugo.
What's her reasons? What could be done to her in the past for her to make such gruesome crimes?
Is it acceptable? Or is it unreasonable?
