In the five-minute video, the singer-performer ranted about why she thinks Duterte, whom she referred to as "Digong-gong," should not be elected as the next president of the country.
Mystica is against the possible curfew "The Punisher" may enforce if he takes the highest position in the land, warning that this could turn out to be another potential martial rule.
"Mismo nga ang Diyos binigyan tayo ng freedom to do everything we want," she argued. "Hindi nga tayo kino-control, siya pa kaya na hindi Diyos mako-control tayo?"
She also dropped the mayor's favorite expletive at the 2:56 mark and continued to reason out how a Duterte leadership would end in violence and bloodshed.
Supporters of the tough-talking public servant did not take this sitting down, and started posting their own video reactions to Mystica's tirade.
One that stood out was a reaction from an overseas Filipino worker from Davao, who referred to her as "Mistake-ka."
