Minamino turned out to be pretty pitiful. I assumed she had some substance and had earned her place next to Fuwa, who was the previous toughest fighter, but it seems like she's basically just a gold digger. Not even a proficient one, either, to misjudge Kanzaki so badly.
Good thing he's not so easily accepting that reality. It seems like another game world, after all. That being said, he will need to make the giant decision of either accepting it and living his life there "normally" or trying to get out, once again. He can't choose both.
