Terra Breaker
The punch didn't throw the oni as far as she thought it would, with the oni having time to wrap her arms around Terra. The oni was stronger than she thought. It was all for naught however, there were other magical girls there just dying to take its head off, even if she was stuck in this stupid brute's arms.
As expected someone threw a spear at the oni, though the strange rabbit doll that appeared out of nowhere was highly unexpected. It was akin to waking up to get a glass of water and suddenly finding yourself having breakfast with two velociraptor. And one of them was speaking English with a heavy British accent.
A powerful aura was permeating the air... power so oppressive that even the most inexperienced magical girl would be able to feel it. A demon of almost imaginable might was here. That.. thing was the one who blocked that attack. Even the usually brash and idiotic oni was retreating as it appears, leaving Terra there as it escaped through a portal. That demon lord certainly didn't look like one, but from the aura it was exuding and the brief display of power just now, it would be miles ahead of the oni.
Terra grabbed her sword, as if to draw it and finally use her magic. But... that scene, that memory came again to her mind, the familiar feel of the worn cloth around the old hilt bringing back memories of her old friend. That unfamiliar sight of her friend crying, the warmth of her blood oh her hands, and her relieved expression as she finally promised.
She closed her eyes for a moment, letting go of her sword, sheathed still in the scabbard.
This was a chance she, or any of the magical people who had fought against these demons, could not pass up. A demon lord was before them, in the flesh and out in the open. What sane person would not kill the very source of the demon plague right then and there? What sane person would let this abomination walk free and unscathed? What sane person would tolerate this heresy upon this earth? Even if the demon lord was stronger than any of the demons they have faced so far, they had no excuse not to try taking it down now.
Terra flew upwards, level to the demon lord.
"Oi." She swung at the demon lord's head. " We're not interested."
