There's nothing I would call a proper "jumpscare" as such, as it's really not that style of horror -- the nearest is at the end of ep 21 and it's: someone unexpectedly runs into a room and another person accidentally knocks over a chair and yells because they've been startled.

Even counting stuff like that, I think the fan-sourced contents warning list found about three instances in 160 eps.

(I am hypervigilant and jumpscare-averse.)
