This is a short anime clip, just over eleven seconds long, centred on the spoken phrase 'too close for', delivered in a tense, close-quarters moment. It carries a nervous, uneasy feeling, as if someone has stepped into space they should not have entered, and it lands best as a quick reaction rather than a long scene.
