It would make perfect sense. The Land of Black Leaves is pretty much Robert's The Path of Black Leaves. And The Rake has made an appearance and Dr. Corenthal has been mentioned. Really, all the framework for has been put in place.
- More or less confirmed as of Chapter 13. The Keepers outright mention a past experience with Reach and Thage, and called The Black King, Mr. Tall, Thin, and Faceless.
- And as of Chapter 20, Slendy's made his first official appearance. Wild Mass Guess confirmed.
Why not? She time travels and Luna's also had an encounter with a Weeping Angel.
Inspector Wakagi is a law enforcer thoroughly frustrated with Inspector Ishida's/ Artemis covering up of the truth surrounding the strange incidents happening all over the country and has recently been seen stealing the corpses of monsters from crime scenes and video taped a teleportation. These actions will lead to The Keepers being exposed to the world at large.
Even though The Rake currently can't get back to Japan, it's already been established that the girls can go on missions to other countries. So chances are if he starts causing trouble again, they'll be sent to deal with him.
Think about Buffy being the Slayer. It could be something similar, but worse.

- Mind=blown.
- Gargouille: gargoyle or weeping angel.
- Nephilim
- Thurs:
- Troll?
- A cyborg like Bunbo was in canon
