Let’s start by making pairs to see what we are working with

96 7b 8b a9 af 88 8a 86 8f 7b 96 87 a8 ad af 7e 86

Look at where number positions should be, they all start with A. Use Hex atbash

0123456789abcdef
fedcba9876543210

69 84 74 56 50 77 75 79 70 84 69 78 57 52 50 81 79

Convert decimal to Ascii
