Normally when a passive buff happens it'll show it on the left side of the screen. But for some reason this specific temari's buff isn't showing up. It also doesn't seem to be increasing anyones ninjutsu if it is working without showing up. I don't know if this is a mistake, but I've had this issue since she was first released. I included a screenshot of the buff on the ninja's tab, as well as in battle with it not appearing.
