You may be right but too bad this image wasn't drawn by nonco though, once Kashima gets better at boxing it would be Nagato who'll end up like this.
By the time Kashima get better at boxing Nagato would probably have master Karate, Kick-boxing, Muay Thai, Sambo, Krav Maga and halfway through with the Shaolin training though

Well, if only nonco draws two follow up 4-komas of Kashima training in boxing and ready to beat the living daylights out of Nagato but seeing Nagato so well trained in martial arts.
Then a follow up image by kinosuke or another artist drawing Kashima injured while wearing her boxing gloves would be nice so that we can discuss more on such images about what martial art Kashima would try to train for next.
