Reborn!: The Silent Tyrant

As for the blurb and all that,

It's basically the story of a female version of Xanxus leading twice as many Guardians to defeat the Mary Sues and Gary Stus who rule the world.

Character introduction: The Xanxus of this story comes with a Godfather's temperament and the ability to tame any "trash."

Xanxus (gender-swapped version) has this to say:

To 27: "A pretty little brat who thinks she's so refined."

To Reborn: "A brat who acts cute and young... ahem, Teacher."

To Dino: "The blondie with the shiny big front teeth and a leaf stuck to one of them. Ahem, Senior Brother..."

Then she lets out a sigh of relief and turns to snap at her poor, pitiful (?) parents

… (ellipsis)

Please forgive me, I'm hopeless at writing blurbs~!!!!!!!
