"What? You killed all of them? You mean, each and every person?" Zero exclaimed.
"Yeah… I did. In my fight with the modified monster created by the demons, I broke through both of the realms. Both of us were insanely powerful and fought without any limiters," she said, staring down.
"First it was the demon realm that was destroyed, then at one moment our attacks clashed and tore through space again. Of course, it wasn't enough to lead us to Nihility, but it opened a portal between the demon and the human realm. It opened for just a matter of seconds, but in that time we got inside it in the midst of our fight.
"And there we fought more. Cities were destroyed with punches and humans fell like flies. I remember Leon, Ellyn, and the others came to stop me— of course, they didn't know it was me since my appearance had changed— but they were being a nuisance, so I killed them off too.
