Unaware Of Danger

''Holy crap! Did you just see that just now? That pendulum was about to slice your head in half! What do you mean "what pendulum?"?''

When someone dodges a series of usually fatal attacks from a monster, death machine, or other thing that could either injure them seriously or kill them right then and there without even knowing it's there. This could be thought of as a form of Stupid Evasion to some extent, but it doesn't fit the definition of the UnTrash at all.
