When a yukkuri attempts to attack a human, but the human is physically unaffected and unharmed.
Note1: Use this tag only then the yukkuri successfully lands an attack, but the human is unaffected. If the yukkuri's attack didn't land in the first place (e.g. a Marisa charges at a human but the human kicks her before she lands the attack, such as seen in post #66070) then it doesn't count.
Note2: Puffing up doesn't count as attempted violence even if most yukkuri falsely believes that it can deal actual damage.
If the yukkuri's attack managed to successfully affect the human physically, use yukkuri on human violence instead (read that wiki page for more details).
