0:12 = 4P6P, 0:25 = 6PPP, 0:17 = H+K, 0:33 = 3KP6P, 0:55 = 3PP. 0:57 = 16P. These are the main moves to look out for and a few others. Punish 6PPP, 3PP, 3KP6P, 16P & H+K whenever you can.
When you fight GenFu with Hitomi, don't stay in his face unless you have the advantage to apply pressure with the 6T Reset Throw and free-cancel mix-ups. GenFu's close range offense is beastly and can overwhelm even Hitomi. Try to play a keepaway game with him to limit his offensive momentum since Hitomi's ranged game is quite strong. GenFu also has an overreliance on punches compared to most characters so you can use Hitomi's 9H Punch Parry against his 3PP, 6PPP & 4P6P spam.
On a different note, I know this is online, but Throw punishment was definitely needed in this match. Don't worry, you'll improve in time.
