Wow, there's no censorship at all in this manga. I thought the anime was pretty rough in that department already, but this is kinda refreshing. It's the least important thing though.
It might be just because I've already seen the anime, but manga makes it much less confusing as to if Maru and Kiru are from the nursery or not. I'm looking for hints and differences too. So far, I like how they made Maru's hand-to-hand skills a secret and that Tokio spoke out about the "additional question".
I don't mind nudity - it's not sexualized in any way tbh, it's just that readers are weirded out by naked bodies.
