Kaito said that he would die for his friends, and it wasn't a joke.

He was in an abandoned building, surrounded by two masked strangers that were pointing their gun at his face. He was tying himself to a wall, looking at the strangers. The masked men wanted to kill him, and he lets them do to protect his friends.

He didnt lie.

He was anxious and scared, looking around nervously.. until someone entered.. it was their friend!

How did they find him?
