Read Rohan at the louvre. i enjoyed it. I liked the art but mostly the colors used. It's basically a little side horror story with Rohan thrown in so no stand battles or anything like that. There's one part in a flashback where Rohan had heaven's door when he shouldn't have but whatever. I know Araki didn't care/forgot but it wasn't really even necessary for heaven's door to be at that part. I wonder when they animate it if they will use the art style in the manga or just use what they're currently using.
