Sigh~ I felt like I read this new chapter too fast or something.. It's so short 😆. It's an Omake after all, huh. I miss all of them so much~ Time to re read, I guess 🤣. Thank you so much, bakagaijin and Admirers of Miss Bertia team!
As a Spirit of Darkness, Kuro has the particularity of being more powerful at night.
Among other things, it means that, while she looks like a one way ticket to jail during the day, she is an adult at night (wow, that sounds bad now that I reread it)
So, guess her and Zeno's relationship.
