I don't think this is it? There must be more chapters?.....(It only said end of chapter 1)

Yup! You're completely right, there's a total of 30 Chapters + epilogue. Everyone, for more information about the series, please go here: https://www.mangaupdates.com/series.html?id=142626
Who's the real Karoku? Or are they both the real Karoku? I thought they were twins.... gosh now this reminds me of what happened to Kuroshitsuji :/ still not over that yet....
Yup I'm still wondering who is the other karoku. I thought he is his mother who has been modified (?) or smth like that, but idk that's just the feeling i get
That's a possibility. 'coz we never really witness the mother died. Hopefully next chapter will explain this...
