I think that too. And, if that's true, it was a nice turnaround in the end. My only question is with Yuma. Maybe it was Hajime in that part, since Yuma was the first to suspect. But the Rei may have killed Kaoru for discovering his secret. Ohh, it's kind of confusing, but at the same time it makes so much sense. I will watch it again, but this time more slowly.
Me too. I was confused about his secret. Maybe he created the game to reveal the truth about Hajime? Perhaps Hajime is the assassin and the Rei is the creator. Ohh it was kind of confusing for me.
