Koji Haneda’s boss code was not left by Koji Haneda, but someone else

Everyone knows that the identity of the boss was discussed by Yusaku and Shuichi through the secret code left by Koji Haneda's case. I thought this code was left before Koji Haneda died, but the latest story The plot clue points to another person.

In the latest story, Amuro remembered a class at the police academy. As an unsolved case, Hiroshi Haneda mentioned that the shogi that Wakasa was carrying was Haneda. Koji's amulet will never leave that kind of death. Assuming that Wakasa and Haneda are a couple, how else would I leave that shogi for 17 years.

The editor tried to combine the wounds of Haneda Koji’s death with this shogi. The result was shocked. It basically matched exactly. Wakasa had a chance to put it before the police came. Shogi is taken away.

If this code is left by Wakasa, and Wakasa is the daughter of Karasuma Renya or an important relationship, in order to avenge rum, he left Karasuma Renya, others Haneda Koji How do you know that Karasuma Renye, who has been dead for many years, is that if Wakasa came back to Japan to avenge rum, the person who regularly uploads Haneda Koji may also be Wakasa. Why can Wakasa go straight to Conan? The current clues are still difficult to determine.
