Xinfu didn't die, just lost his left arm, just like his father (killed by Makishima Shogo).

Kougami Shin 'ya is free, right? He lives alone.

Tsunemori Akane is the same, only stronger.

Kagari Shuusei died in the middle.

Makishima Shogo was killed by Kougami Shin 'ya (crying)

Then the society is still like that, ruled by the system.

It means that you may be incompetent, and that's about it. I hope it helps you.
