Description of the problem you are experiencing : Akatsuki Creation Hidan's chase applies the unavoidable tag as it's supposed to, however Ay (Fourth Raikage) doesn't interact with Hidan's unavoidable chase tag properly. Ay doesn't automatically target the unit affected with the unavoidable tag with his secondary standard attack, instead doing his default standard towards a random target and/or using his secondary standard attack to attack a unit afflicted with a normal tag. I also tested this interaction with Edo Tobirama's mystery which requires the target to be afflicted with tag in order to reduce the skills cd, and both Hidan's standard attack's tag application and his chase's application worked properly to reduce Tobirama's cd. So it seems Ay is bugged.
