What Masamichi Yaga feared most finally happened.
Yes, Satoru Gojo was ultimately corrupted by that humanoid thing, Sherlock!
After the investigation team led by Masamichi Yaga submitted a report stating that "there were no traces of Time Vessel Association activity in Okinawa Prefecture," Tokyo Jujutsu High's fifteen-day "investigation" officially came to an end.
