[The undead weren't very discriminating with who they went up and tried to be 'courteous' to, and this ended up being a mistake. Because there was another undead near Diana who made a mistake and chose to try and touch someone who had no qualms about swinging his tonfa around and caving the creature's face in.
It also had the unintended side effect of slamming into the undead bothering Diana and cascading them both into a wall, probably leaving a dent. Hibari didn't care, it wasn't his property. Instead he was looking smug at the mess he just made.]
If you're going to be so cowardly about striking back, nothing will get solved.
courtly cadavers/ let the asshole brigade begin
