UP THE RAINBOW PATH
Warning: If you save aboard the ark you can't leave again. If you want to do things anywhere else, do it before boarding, and/or save on a different save file.
He has three moves. When he doesn't shake and swords don't appear, slow down time, get out of his way and and hit him once he stops. Then (slow down time again and/or use Steel Fist Sake and) bash the sword.
Get three heads drunk twice and hit the bell. This time each of Orochi's heads takes different amounts of damage from slashes, fire and attacks, and once you have the fire head stunned do big damage with water!
Bash away until he loses his armor, and use wind to remove the flames. Then, I strongly recommend Steel Fist Sake and slowing down time when you attack; you can beat him in just one round.
Each time you deal enough damage the boss relinquishes another ability. Start by bashing him while he's not glowing. Restore the floor with Rejuvination. Slash him with Slash. With Greensprout, Bloom him and bash the little blue ball.
Now he's a slot machine. As always you regain an ability whenever you've damaged him enough. For the most part, slash back whatever he throws at you. When 5 ice crystals appear in a line, slash them all back!
This is the hardest form. He requires lots of damage. Hit him whenever you see the little blue ball. You can hit his missiles and (if you're fast) his fire back at him.
Turns out Issun is doing his part! It's amazing how much support he can rally in a short time. Call me fruity but this part gives me goosebumps, in a good way.
Draw the Sun right away. Then the little blue ball becomes exposed for a LONG time. Use Steel Fist Sake and slow down time at least twice for maximum damage as you bash it. Then attack whenever the blue ball is visible.
