Mashiba's flashback continues with him being released from prison to see his probation officer. He's taken to the location that he and Kumi will now live in, and he's introduced to boxing.
We see the time when he fought Miyata, and that his murderous impulses were taken down when Ippo defeated him. We also see that his probation officer passed away from health issues.
Mashiba thought himself alone, but now he has a crowd of people cheering him on. It's time to try being the champion, but it's also looking to be 50/50.
