Draw Slasher

Demon Samurai is the boss at the end of Chapter 7, and is the last boss you face. This boss is quite unique in that you do not attack him directly. Instead, he throws up waves of ninja icons on the screen, and you have to slice them all before they go red. You deal damage to him for each icon you successfully slice, but take damage for each one that you miss. During this fight you will also periodically have to defeat waves of standard enemies. There is nothing overly difficult with these sections, and if you are efficient, you can actually regain some health during these parts. Fully upgrading your stamina bar helps during this battle as it allows you to trace longer slices over the icons.

Once the battle is done you move to an interactive cut scene. You will see a white slice mark that you can trace with your finger. Doing so will decapitate the Samurai, earning you this trophy.

Completing Chapter 7 will also unlock 1 more Challenge (19), and the Samurai alternative character.
