"Thus Spoke Rohan Kishibe series may be considered canon, while others like Buso Poker are not related to the series at all" blatantly points out that not all the characters in the oneshots category will be related to the series. This wiki typically includes all works from Araki, so it's not really that much of an issue. It only seemed fair since Araki decided to combine it with two other JoJo one-shots in the Under Execution Under Jailbreak volume.
