Kamui

Kamui, which is explained to be the northern tip of Nippon, is a frozen island.  Which is why you needed to take an underground tunnel to get there.  Find the nearby save spot.  Explore the field and beat off any attackers – they look like Tikis that go lost on their way to Hawaii.

Enter the hut.  Ammy relaxes by the fire when a man wearing a Gummy Bear mask flashes a sword.  The guy cautiously escapes and Issun admires his sword.  When you leave the hut, the Gummy Bear is waiting for Ammy.  Before the fight a picture is shown of Oki and I guess the brush adds 10 pounds because the guy in it is totally buffed out.

 BATTLE AGAINST OKI

•  Use a vengeance slip to deflect the icicles he shoots at you.
• Slow him down at every chance with mist.
• If you do get hit by an icicle and freeze, draw a flame line from the bonfires.
• Take steel fist sake to speed up the battle.

When you drain the masked man’s power, he will get into Michael J. Fox mode and turn into a wolf.

 BATTLE AGAINST WOLF OKI

•  Keep using Steel fist sake.
• Use mist constantly because he is fast.
• Attack with bombs – each one will take away about a fifth of his power.
• When halfway damaged he will split into three and attack even faster.
• Stop this threat with the mist technique and try to attack the main, colored wolf while avoiding his clones.

Cinematic: He turns back into a masked man name Oki.  I think Ammy got a little turned on by all this wolf transformation.  He is from the Oina tribe.  Is that the music from the opening credits of MASH?  Oni recognizes Issun and knows his back story.  He has armed himself because the demons Lechku and Nechku have infested their sacred mountains and killed his tribe.  His sword will glow when it is time to kill.  Note: the sword is not named sting.

He repeats a prophesy: “The wall of ice shall shatter and open the way to the heavens when Kutone, the guardian sword, glows silver.”
