The Master Ninja - Walkthrough

 

Jin is a rather challenging boss, and will punish overaggression harshly, debatably more harshly than any other boss in the game.
The key to this fight is spacing. The best way to beat him without cheesing him is to keep him at mid range, and move forward to bait a combo from him. Wait for his combo to finish and punish before he recovers. Attack until he blocks (two, at most three successive swings), back off to recover your own Ki, rinse and repeat.
Keep your guard up in case he chucks Storm Kunai or Fire Shuriken at you - damage from his Fire Shuriken can be negated by blocking when they explode if you are stuck with them.
Jin utilizes a rather familiar ranged attack at range, and sometimes up close as well, that attack being the Art of The Inferno. Erm... "Flame Dragon," as its called here, that being him swathing himself in fire and then throwing a fireball at you after a two to three second windup, you can avoid this attack be either sidestepping or just jogging to the left or right.
Be wary as well of his charged attacks, one of which is the Izuna Drop. All have similar windups and will likely oneshot you; retreat to mid range when he stops moving and places his sword behind him to wind up.
Jin has two highly punishable jumping attacks, one of which is a double overhead swing in the air and the other is the Flying Swallow from NGO; a jump and midair lunge forward straight at the target's face, that target being you. This attack should be dodged or interrupted before reaching you, as it will instantly drain most if not all of your Ki to block and he will be more than happy to follow up his jumps with a light combo and a haughty comment about pride being your downfall. That said, to those of you who are feeling brave and have throwables at your disposal: if Jin is hit at any point in the air he will flop neatly to the ground and be open for a Final Blow, much like Saika Magoichi. You can even use the Flame Dragon scroll or windup knockbacks for Living Weapon to catch him in the air. However, melee strikes against these attacks are at best unreliable seeing as both of Jin's midair attacks are faster than and outpriority your own.
He is fair but requires near perfect awareness of spacing and a thorough understanding of his patterns to beat, so you will likely die quite a bit trying to learn him.

Fortunately this mission has next to no consequence for dying considering the mission is literally just Jin and nothing else.

So. As for the cheese? Jin doesn't like rocks. Specifically the rock to the left of the arena, putting this between him and you will confuse him and buy you time to safely charge up an Iai Quickdraw or start the windup of Renegade Dragon or similar attacks while he walks around the rock. It's that simple, but be warned ye who run the Abyss: there are no rocks to save thee.
