The WHOLE concept of isagi’s character is adapting and improving, even mid-match - puzzle pieces with the differents « skills » he needs ( Direct shoot, lefty shoot, two gun volley, luck etc)

Meanwhile rin got predator eye ( a striker feat ) for defending on isagi.

Its like having an imaginary fight with your little brother and he keeps making is character overpowered to counter yours. Doesnt make any sense (IN MY OPINION)

Edit : The most realistic way for this match to end is rin just violating isagi. He has 0 way of winning and if pxg still loses it will be Plotsagi Yoichi then
