Vol. 6 - Chapter 75

Keiko's sword continued to tear through demons, even as her eyes mostly remained watching over her back in case someone had any ideas. That "someone" who she was worried about, of course, was her grandmother who was currently doing the same just a few meters away. She could feel eyes landing on her, every now and then, though, every time she turned to see if anyone was looking to sneak in a stab in her back, she didn't see anyone. Most of the warriors were too busy either narrowly defeating their enemies or dying to them. 

... Maybe I'm just being paranoid,  Keiko thought for a moment, as she side-stepped a clawed hand that attempted to come crashing down on her from above. She retaliated by way of a horizontal slash across the demon's abdomen, which caused its monstrous guts to come spilling out onto the stone.
