This was the first "fun" boss fight. Just challenging enough to be enjoyable without being frustrating. It only took about 2 or 3 tries. Firecrackers can stun the boss for some extra hits. Use the grapple to close the distance when the green icon lights up on the boss. If you have the grapple strike type move unlocked you can come in with a free hit as well. I used the red sugar item at the end to do some extra damage.
This is your first Shinobi Execution and awards a memory which can be cashed in at a statue for an attack boost. Also you get the ability to upgrade prosthetics when you talk to the sculptor. I show some of that here.
So far the game has been very difficult and I am horrible at parrying, deflecting but love the game. All the different paths make it addictive since you can try 3 or 4 different bosses or routes often, if you burnout on one, get stronger come back and kill the boss you struggled with. Thats the main pace of the game so far.
