Proton Jon plays Ninja Gaiden - Act 6, Part 2 of 2

Finally, we end this bad boy.

Once you snap your father out of it, Jaquio will try to kill you and your father. Ken sacrifices himself in order to save his son.

It's now a fight between Ryu and Jaquio!

vs. Jaquio

Leap off the wall and hit the Star of David in the middle of Jaquio. The fireballs will try to home in on you, but they don't do a very good job. If you can stay on the bottom as the fireballs come by, or if you stay on the opposite end of the screen from Jaquio, they won't really be able to loop back around to try to hit you a second time.

You'll save the girl, get a typo, and then find out you have to throw the statues from the top of the temple before the "black moon" shines. Unfortunately, you're too late, and now you have to use the Dragon Sword to take the demon down.

Stage 6-5

Hit the head until it falls, then take down its wagging tail. Then, take down that purple orb of a heart until it's dead.

All the while, you'll be avoiding the fireballs that come out of the top of the demon. Just be careful and be patient.

After you destroy the demon, Ken Hayabusa dies, and Ryu and the girl escape the temple before it crumbles. Foster orders the girl (code name Sea Swallow) to kill Ryu Hayabusa. Ryu overhears this and swears revenge against Foster, before taking the communicator out of the girl's hand and throwing it into the forest below. Ryu and the girl kiss, and we finally find out what the girl's name is: Irene Lew. They both stand at the end of the cliff and watch the sun rise.
