I'm at the part after you use the USB at the computer in the bathhouse's secret room. The game says to talk to Seryu.
I keep talking to him but he keeps saying "if you want to quit I'll take you into witness protection". He doesn't say anything else and I can't progress the game.
I've talked to him at day and at night, and after sleeping as well. The game doesn't continue, I think the flag for the next event isn't working properly. I've talked to every other NPC to see if I'm missing anything, but it doesn't change anything.
Suzaku and the note say to talk to Seryu so it must be what I'm supposed to do, but its not working . The game's basically softlocked now.
