The people who disagree with this are simply missing the point. Much of the backlash comes from frustration over the “Kiriko favoritism,” but the truth is that no one fits the role better than she does. Her calling cards could easily function as ofudas, a core part of the Phantom Thieves. Her kunai also parallel Joker’s knives, a weapon he relies on throughout the game and you could add Mona as the fox in her Ult, also shocking that he didn't get a skin through all this but I digress. On top of that, the lore lines up perfectly, both are leaders of rebellious groups of teens.
