First of all, thanks for your great job. Second, an advice: in episode 9, when Ogi is about to begin the pro test he is given the number four which, in japanese has the same pronunciation as "death". That would explain both his expression and Kenzo's in that moment. Adding a note to the subtitles would be convenient, I think.
What? Don't be silly. 4 was Ogi Shunsuke's number, which is why both Ogi and Kenzou were so surprised. Kenzou had already realized Ogi was still alive in Asahina, which is why they were both shocked that his number was given back to him.
Anyway, final episode:
[spoiler]COPOUT!!! But it was a happy ending, so that's ok GO GO SHUNSUKE! GAME SET![/spoiler]
