Evidence, Proof
What I say is correct 100%! You may use it as evidence in this murder case.
You convince the officials questioning you that your evidence can be trusted and it's proof that you definitely didn't have anything to do with any law breaking or murdering.

None
The officials force you to present this evidence in front of the Shougun (しょう), himself. Your knees quake, you feel like you're gonna be sick, but you try to stand up tall and tell him everything. After all, you know your proof is correct, so you shouldn't be so scared.
You better hope the Shougun believes your evidence is accurate, because he's known to kill people willy-nilly when he thinks they're lying.
