Catgirls And Dungeons (Yuri)

I was on my way home with my friend when suddenly, I spotted a catgirl cosplayer who made my heart skip a beat.But something felt offI couldn't recall seeing her in any anime, manga, or games I had ever come across. Confused, I asked my friend standing next to me.To my shock, his response sent chills down my spine:"Huh? What catgirl? What are you talking about?"Suddenly, a truck came barreling toward the girl. Without thinking, I rushed to save her. In the end, both of us were hit by the truck.Now, I find myself reincarnated in another worldin the body of the very catgirl I had seen.But... who is this girl?How is she related to the dungeons that keep popping up in this new world?
