-->'''Light''': All those people fighting for justice, they lose. You want a world where people like that are made to be fools? Look at yourself, Miyako. You just made yourself a fool. Unlike you, who constantly denied her best friend is a thief because of the similarities, I immediately knew she's the thief we've been hunting down because of the similarities. You are a useless detective, Miyako. Do you hear me? Useless! Useless because you refused to believe your best friend is the thief we've been hunting down. If you want to be useful, kill the others! Shoot them! Shoot Maron and Chiaki!
