S1·E22 The Profiler

The second round of the finals pits Akiza against Commander Koda. Koda has been ordered by Goodwin to expose Akiza as a signer, which didn't work on Akiza's last duel. Furthermore, Koda can expose his opponents' past to disable them. He doesn't take long to expose Akiza's troublesome reputation as the Black Rose, awakening painful memories to Akiza.
