As many of us thought, looks like it really is an attack by Valkyrja and Laughingcat. They mentioned that the purchase happened around the time when Koreeda was involved in the car hacking case, which is after Valkyrja and Laughingcat decided to take Sakai down and get Koreeda on their side, so it makes sense. I wonder if it just took this much time for the investigation to point the finger at Sakai naturally, or if they did this to his brother's account back then and only recently blew the whistle. Also, I remember Sakai and the team in the building figuring out that Laughingcat messed with their router, but did they ever find the backdoor he installed to watch Koreeda? If not, maybe that's how they somehow got into Sakai's account. Anyway, keep up the good work. Looking forward to the next release!
