Early on, any time that Ayaka turned herself into fire resulted in a Curb-Stomp Battle against the Tower Witches. Even the older, more experienced witches approach her carefully. It also helps that she has effective immortality and a living, nigh inexhaustible pool of magic power in Takamiya Honoka.
If you think that Ayaka is badassed, wait until her mother, Kazane gets going. Since she is a BarrierMaiden, she doesn't get to use much of her magic in a fight. Instead, she settles for using her fists.
The Kaiju-sized battle between a giant bear and a giant bunny.
Evermillion's first seal is undone and we get to see just why the Tower Witches want Honoka so badly. Evermillion's first act is to knock Medusa out with a mere hand swipe! The resulting release of power completely annihilated the Kagari mansion and even a portion of the school.
Small one for Medusa as well for getting right back up, pissed off and raring to go again.
A villainous example: Weekend. The woman takes Kazane, the strongest known Workshop Witch in the series, out of the picture within ten minutes of her on-screen debut. How did she do it? She blew up the city. Her plan to acquire Takamiya Honoka is a massive combination of Batman Gambit upon Batman Gambit with healthy does of Crazy-Prepared and Stuff Blowing Up.
