Indicators: >!startled, followed by, leader jumping forward from own seat (one of those is an anagram indicator, the other is a linking word telling us how the parts of our answer will be arranged, and the last one is a selection indicator paired with a special technique in order to alter selected fodder)!<

Fodder: >!shogun, samurai (these words or parts of these words will help us construct an answer)!<
