This is when Strike ninja well struck throwing a dagger at the butterfly in the hopes of hitting it. 

"Well I guess there really is nothing else to but to see if we can find the couple weather they be alive or........dead" Crimson said hoping no one had seen Stroke ninja just yet. Soon enough he would find out if this 'butterfly' was abnormal or not. Part of him thought it was normal but the other part was preparing to feel pain if Strike ninja gets destroyed.
