For the trophy, Unlike the others, you need to complete a single level by pressing R2, which is the basic attack. That means that while it is possible to do that in a level of your choice, I don't recommend it as I tried 3 different levels, and due to different enemies, it cuts out some levels, in my opinion. Chapter 1, "Uninvited Guests," would be the perfect level. It's short and has fewer enemy types because it is the tutorial level. I will try to pass the information by text to help you the best way I can; keep in mind that you can die as many times as you like **AS LONG AS YOU DON'T PRESS R2.** FYI: Don't press R2 to destroy the walls, as it will count, and you will have to reload the level from the start; I will show an example of the said wall not to use the sword.  1. To start, throw a shuriken to the enemy while grinding on the rail to disrupt his barrage. 2. Parry the second as he is alone, and he will charge at you with his bat. 3. You can either throw 3 shurikens for the 3 enemies together, or you can parry, and when you see the next one coming, blow them away with Tempest to give you time for the next parry. 4. After you descend from the ventilator system, there will be 3 separate enemies, making it perfect for three deflect kills as all are blaster enemy type. 5. When you get to the cargo area before the train sequence, you can either ignore it, as it is not an area where you must defeat all opponents for a door to open, or avoid confrontation and head to the next area or fight the two melee and throw a shuriken to the blaster guy. The next steps are practically the same, so remember to SHURIKEN THE MINI GUN TYPES, DEFLECT THE RIFLE TO REDIRECT THE SHOT, AND PARRY THE MELEE GRUNTS. Last advice: equip the FLUX ability to clear quickly the two big arenas in the chapter. See the video to see what I mentioned in this post in action.
