How many chapters is this in total?

You will have to wait for years. Even the novel is not completed with already 4 volumes. There is no signs of the story ending anytime soon either.

Do you know if the novels are translated or not?

The translation is up to all the published volumes and chapters.

Thank you so much for the novel translation! ε=ε=(ノ≧∇≦)ノ

Thank you! It sounds kind of weird to say that mangas introduced me to novels but its true lmao. Im so addicted to novels lately
