The Voynich Hotel, a really fun manga about a very interesting hotel. It’s definitely up there in myv list regardless of it’s anime status (which is currently nill)

Spirit Circle. I don’t feel like I can describe it in a way that does it justice. There’s past lives, some of which are actually in the future. There’s a tsundere antagonist trying to murder the MC. Some asshole is trying to philosopher stone the world. Just go read it, it’s great.
