Reimu's speedy attack took all four imps by surprise.  Her strike was true and the single downwards stab to the imp's back struck in a lethal place.  The other three imps were stunned for a moment as the fourth imp cried out then fell to the ground clawing at the ground as he bled a blackish red blood and quickly collapsed.  But the other three imps seemed to recover from the shock.  Gibbering in a language you couldn't understand, one fell back and began casting a spell as the other two stood between you and him and flexed claws, preparing to attack.<br/><br/>The surprise round went well, but now they were ready to fight back.
