Fist of the North Star: Ken's Rage

Rei, Shin, and Thouzer are the main users of the Nanto Seiken fighting style, though any other character can use it once they've learnt the Extrinsic Skill "Nanto Seiken Wisdom" and equipped it. Normally, as any of the 3 characters mentioned above, for a kill to count, you must kill an enemy with a combo that ends with . The enemy will die with a slashing effect if done right.

Using Rei, the best way is to spam after a successful Timely Strike. GenocideHeart adds that Thouzer is also a good character to use for this. For any character (including the 3) that equips the Nanto Seiken Wisdom skill, any attack they use to defeat an enemy will count towards this trophy, including regular attacks. For now, Dream Modes are the best place to farm this.
