Can necrophilia or zoophilia/bestiality like in your hentai work, Japan? It's an option, right? Great content otherwise, Japan. I wonder what you'll give us next.
I like Nana's character, but her justification for killing isn't almost clear, meaning, the organisation explaining it in a few panels/pages? That's not enough. They could have done better than that.
I thought the girl was immortal, but she isn't if that's how her powers work. Her kill count would manifest through the talented she's healed (that's how I understand it).
