Koichi had not been by the shrine at the point of attack. However, je was making his way there. The peace of the town alone was unacceptable in his eyes to be ruined. But he'd be damned if he allowed anyone to ruin the shrine. His favorite spot to enjoy a peaceful quiet day. Not to mention he could pick up a few things in the base of the Foundation which was accessible through the Vongola base his father had shown him. He was the current head of the Foundation after all. There was no time to waste. As he approach he sighed seeing another group of men. Ten to be exact. "Fools. Only the weak group up like that." he said as he proceeded to dispatch each of them with relative ease. Now the question was would he meet with Ami's group first or would he get to the base. 

(I'll leave it to Jake to decide whwther or not Ami see's Hibari :P)
