Like in the title.

Passive Courage for Asuma (Taisho Period) does not work.

Whenever he is hit with mystery skill (and I tried him on +1000% mystery infinite illusion), there is no indication about stat increase. I thought "ok, maybe it is just visual bug" and used my alt and then Kakashi to do some testing. Hit Asuma with 3 mystery skills and yet damage from his mystery (pure nin, which matters because that means he can't increase damage from it with his Fortune Prayer passive) did not increase at all, which shouldn't be possible considering Asuma's Ninjutsu should be up by 60%.
