I am convinced that Sekimukai isn't doing this at the government's orders... not that I don't believe a lot of politicians would be WET to have the power of a god, but... there is something strange here.
There is only so much you can do against another organization that refuses your requests when you and that org are technically aligned in your overall function, Tsuzura IS an essential pillar to protect society, there is no way the secret assassin org that has been hinted and a few psychotic mercs can be counted in keeping things under control.
Now... a rogue agent that represents a very confidential side of the government that much probably has few representatives because of the need for secrecy and specialized abilities, having practically total control over the flow of information, and being a greedy, depraved creep wanting to achieve godhood or whatever... that starts to make some sense.
I want that Nanao brat killed, traitors don't deserve forgiveness.
